Mares Puck Pro vs. Mares Puck

Comparing the Mares Puck Pro with the Mares Puck

Mares Puck Pro - White

When Mares introduced the Puck dive computer, it rocked the boat. It was an affordable and delivered all the necessary functionalities that are expected from an entry level model.

The outstanding feature of the Puck was its single button navigation. It made it very simple to use even when diving in cold surroundings and wearing thick gloves.

The Puck Pro was the logical successor which had to follow one of the best dive computers on the market. Mares was able to keep all the great things of the Puck and added some elements to make it indeed even a better computer! Check out our detailed review on the Mares Puck Pro!

However, are these improvements worth the additional price? Does it make sense to upgrade?

Design Differences

At first glance both devices look rather similar. They both are roughly the size of a hockey puck (hence the name). The button on the Mares Puck Pro has been moved out of the display area to the bottom of the case. This allows for more display area without compromising the ease of use coming from having a single button to navigate the different functions.

The diameter of the Puck Pro is slightly larger. On the other hand it is less high than the Puck. This makes it overall more comfortable to wear and less clunky. The larger diameter combined with the different positioning of the navigation button provides a significantly larger display area on the Pro compared to the original model.

The display on the Puck Pro is also somewhat better to read without backlight in semi-darkness. This can at times be helpful but it is not a huge factor when deciding which dive computer to buy.

Features and Functions

There’s not a ton of functional differences between the Puck and the Puck Pro. The most talked about difference is that the Firmware of the Puck Pro can be upgraded.

This at first sounds like a great feature. Realistically it’s probably not that big of an issue. A firmware update will typically not include an upgrade to the decompression algorithm or any other necessary software in the computer. Having said that, the feature comes in handy if there was an programming issue with the firmware that would require updating.

The other big difference is that the Pro can handle two different gas mixes while the original Puck can only handle one gas mix. This is a great feature if you have different mixes you use during a dive to optimize bottom time.

The algorithm in the Puck Pro got a minor update and seems to be slightly more conservative. The changes do not seem to be significant though.

There are no significant differences in most of the other functions including the log book. The logbook is sufficiently large but seems rather small compared to other dive computers like the Suunto Zoop Novo.

Mares Puck Pro - Lime

Conclusion

The most visible improvement of the Puck Pro vs. the Puck is the larger display. The different placement of the navigation button increases the available display space significantly. The Pro also feels more comfortable as it is less thick.

Under the hood the most significant improvement is the ability to work with two different gas mixtures. This can become more important for more experienced divers which means that the Pro is a device that a diver can use for a longer period of time.

Do these two features mean that you should drop your Puck and run to get a Puck Pro? No, not at all. However, if you are looking for a new dive computer then spend the extra bucks and go for the Puck Pro instead of the Puck. Over time, the additional investment will be well worth it.

Suunto Zoop Novo vs. Suunto Zoop

Comparing the Suunto Zoop Novo with the Suunto Zoop

Suunto Zoop Novo - Yellow

Early in 2016 Suunto introduced the Zoop Novo as the successor of the very successful Zoop. The Zoop itself had been on the market since 2010. Since then it became one of the best-selling dive computers in the entry-level segment. The Zoop Novo has big shoes to fill if it wants to become as successful as its predecessor.

You can read our review of the Suunto Zoop Novo to learn more about its overall features and capabilities.​

Will the redesign to the Novo continue the success story? Is it worth upgrading?

Design Differences

The looks are overall very similar. The Zoop had three buttons while the Novo has four. This does help with cleaning up the overall navigation and actually making it easier to use the different functions.

Suunto Zoop Novo - Black

Suunto Zoop Novo in black

Suunto Zoop Dive Computer Black

Suunto Zoop in black

The Novo has a slightly larger diameter than the original model. On the other hand it also is a little slimmer. It actually nearly doubled in weight to 120 grams (4.23 oz). This overall indicates that the Novo is built more robust. Not that the Zoop had any problems in that area though.

Suunto did improve the display quite significantly. Not only does it offer two backlight options now but it also features a similar dot-matrix screen like the higher end models from Suunto do. This allows to display pretty much any sort of information without having to use abbreviations or other display mechanisms to get the data across.

The backlight options now include an active backlight that is activated by pressing the menu button down. The screen is also phosphor-luminescent which makes it glow in the dark when you shine a dive light at it. That’s a convenient method to be able to view the data while not having to burn through the battery using the built-in backlight!

The Zoop Novo also uses the cable port that is similar to the D-Series and allows an easier connection with the cable than the clamp style connector that the Zoop used.

Features and Functions

Suunto changed quite a few software related features with the introduction of the Zoop Novo. The overall software is similar to the one used in the D-Series. It splits the menu up into 4 easy to use sections.

The logbook functionality has been significantly improved. The original Zoop was capable of keeping a 50 hour logbook. The Novo nearly tripled that memory to a staggering 140 hours. Another new feature is that the sampling rate can be adjusted to 10, 20, 30 and 60 seconds and in freediving mode to 1, 2 and 5 seconds. The Zoop sampled at a fixed sampling rate of 30 seconds.

Overall, the algorithm in the Novo has slightly changed as it can handle Deep Stops now. The original Zoop was not capable of doing that.

The Zoop Novo also has more dive modes as it can handle gauge and free dive in addition to air and nitrox diving.

Suunto Zoop Novo - Blue

Conclusion

The most important improvements are clearly the better display and the simpler menu structure when you compare the Zoop Novo to the original model. The backlight has also improved a lot which helps when you dive in darker environments.

Having more memory is nice but not necessarily a big sales point. You can always offload your dive history to your computer and keep as much data on there as you want. The overall capabilities of the log book with adjustable sampling rates add more flexibility to the overall functionality.

Lastly, if you’re not only into air or nitrox diving but do some free diving then the upgrade is a significant improvement for you.

If you own a Zoop and are happy with it then don’t run out to upgrade to the Novo. If you’re looking for an entry-level dive computer and try to pick either the Zoop or the Zoop Novo then it’s worth the slightly higher cost to get the newer model. You will get a state-of-the-art entry-level dive computer at a great price! Click here to find the lowest price!

Mares Puck Pro Dive Computer Review

The Mares Puck Pro provides the basic features that are expected from an entry-level dive computer. This in combination of its cheap price tag make it a great choice for beginners as well as experienced divers that want a backup to their more sophisticated device.

Mares had introduce the Puck dive computer in 2008. It turned the market upside down with its simplicity. The concept of a single button to navigate all functions was new and specifically new divers loved it. The Puck Pro is the successor of this original device and it has some great improvements.


Review Summary of the Mares Puck Pro Dive Computer

Experience Level

Suited for the beginner or as a backup device for experienced divers.

STYLE

Oversized watch style. Cannot be worn as a regular wrist watch.

Ease of Use

Super-simple navigation with single button.

Price Level

One of the most affordable dive computers available.

We Like

  • Large and clean display
  • Simple to use
  • All features that an entry-level diver could need
  • Large log book to store dive information
  • Off Mode to take the computer out of dive mode completely
  • Personal dive profiles to adjust algorithm to be more conservative

We Don't Like

  • Too big to wear as a watch
  • Does not offer air integration

Summary:

The Mares Puck Pro is the successor of the very widely used Puck. It builds on the simplicity and easy of use of the original device yet improves where things could be improved. The simplicity is the outstanding feature of this entry-level dive computer. That, and the great price you can get it for. It doesn't have any advanced functionalities but none of those should be expected at this price point! Overall it's a great device for the beginner diver or if you're looking for a backup dive computer.

Mares Puck Pro - Black

The Mares Puck Pro is a quite large dive computer. Some compare it to the size of a hockey puck. This does have advantages under water as it's easy to read the information on the display. It does mean though that you can't use it as an everyday watch.


The Puck Pro is available in a variety of colors:

  • Black
  • White
  • Yellow
  • Lime
  • Red
  • Blue



Capabilities

The Mares Puck Pro might look like a wrist watch but it is a quite large device. It's over 2 inches in diameter and close to an inch thick.

The large size allows for a large screen that displays all important data without having to search for it. There are three different dive modes available:

  • Air
  • Nitrox
  • Gauge
Mares Puck Pro - Red

​The large size of the Puck Pro allows to display all necessary information on the screen while still providing a great fit on your wrist. The single button navigation works great even if you're wearing thick gloves. However, it can be a little tedious to having to scroll through all options as you only have a single button to move through the different functions.

The display comes with a sufficiently strong backlight. The backlight duration can be set from 1 to 10 seconds to preserve battery.

The Puck Pro features audible and visual alarms:

  • Ascending too fast
  • Exceed safety for ppO2/MOD
  • Nitrogen saturation equal to 100%
  • Decompression stop violation
  • Low Battery

Technical Capabilities

The Mares Puck Pro is capable of handling oxygen mixtures between 21% and 99% for Nitrox diving. You can adjust the pO2 levels between 1.2 bar and 1.6 bar. The max. depth is up to 150 meters (492 feet). Altitude adjustments can be made up to 3,700 meters (12,100 feet).

The underlying algorithm is based on the Mares-Wienke RGBM model. The conservatism of the algorithm can be adjusted through different settings. This increases the safety settings if you prefer to stay on more conservative and safer settings.

Dive Log and Connectivity

​The dive log has a capacity of up to 36 hours at a sampling rate of 5 seconds. This provides a reasonably sized log of your most recent dives. You have to wait until the data is overwritten as you can't delete from the dive log yourself. You need to transfer your dive log to a computer if you want to avoid data to be overwritten.

The USB connector is sold separately. It allows to transfer your dive data to a computer where you can analyze it further and use the data to plan future dives.

Missing Functionality

Any entry level dive computer like the Mares Puck Pro has features missing that are available in higher end devices. The Puck Pro is in line with pretty much all other basic devices and is missing capabilities like a built in compass and air integration.

Neither of these features will be missed by beginners and as this dive computer is designed for that group it's not an issue that the functionality is not there. Unfortunately, this also means that you can't expand the capabilities of this gadget and will then later on have to upgrade to a different device. You can always keep the Puck as your backup scuba watch though.

Features/Specifications

  • Simple single button navigation
  • Large display to show all important information on the screen
  • Three dive modes for Air, Nitrox and Gauge
  • Audible and visual alarms
  • Nitrox settings between 21% and 99% with PO2 settings ranging from 1.2 to 1.6 bars
  • Mares-Wienke RGBM algorithm
  • Maximum operating depth 150 meters/492 feet
  • Four altitude settings up to 3,700 m (12,100 ft)
  • Supports both imperial and metric data display
  • Dive log up to 35 hours with a pre-set 5 second sampling rate
  • User replaceable Lithium battery (CR2450)
  • Six different colors
  • 2 year limited warranty

Pros and Cons

The Mares Puck Pro is an excellent dive computer for a beginner or to use as a backup device for an experienced diver. It is built solid and will reliably work. Mares has done a great job improving on the already excellent Puck.

Pros

  • Great display to show all important data
  • Adjustable RGBM algorithm
  • Three different dive modes (Air, Nitrox and Gauge)
  • Easy connection to a computer
  • Simple navigation with single button interface
  • Easy to use even when wearing thick gloves

Cons

  • No built-in compass
  • Missing air integration
  • Too large to use as a wrist watch

​You get all functionality you would expect from an entry level dive computer. It's missing the bells and whistles that can be found in more expensive devices like compass or air integration. This missing functionality is reflected in the rather low price of this scuba computer.

The dive log can't be purged which makes the Puck Pro not usable for dive shops that rent out dive computers. This is not really a negative factor assuming that many beginner divers will probably want to purchase their own device in order to build up their dive logs, etc.

Where to Buy?

Lowest prices as well as fastest delivery in combination with the best service are usually found at Amazon.com. Ordering the Mares Puck Pro at Amazon is not exception to this rule. You can find all available colors and accessories at the lowest prices.

Customer Feedback

You can find many comments online from other divers that bought the Mares Puck Pro. Overwhelmingly, the feedback is positive. The only issue we found in the reviews is that you need to replace the o-rings when you need to change the batteries. You should be aware of that so you can order them separately beforehand.

One other review stated that the dust cap on the battery compartment was not correctly placed when they received the device. They didn't know that at the time and when they took the device under water the battery compartment flooded and rendered the gadget useless. They could return it but you might want to check that the battery compartment is correctly closed before using the Puck Pro!

Conclusion

To conclude this review on the Mares Puck Pro Dive Computer, it is a cheap yet reliable and efficient dive computer. While being an ideal choice for entry level divers, it could serve the purpose of a decent backup dive computer for professionals.

With such a low price, it would be a mistake to expect advanced features that are only present in high end dive computers. So before you make a buying decision, it would be a good idea to actually think about your requirements and then compare it with the pros and cons highlighted in this review. This will definitely help you in the decision-making process.

If you decide that the Mares Puck Pro is a suitable dive computer for your needs then you will definitely be satisfied with your purchase. It provides all necessary functions and works reliably.​

Whom is the Mares Puck Pro not for?

​If you gained more experience as a diver and require features like a compass or air integration then this is not the right computer for you. You will have to look at higher end devices like the Suunto D4i Novo to provide such features.

The Mares Puck Pro does its name justice. It's puck sized and as such not usable as a watch you wear every day. On the bright side, this does allow for a large screen to display all important information. If you are looking for an entry level dive computer you can use as a watch then have a look at the Mares Smart.

Suunto Zoop Novo Dive Computer Review

The most important aspect that you should be looking for in a dive computer is whether it is built for amateurs or professionals. As far as the Suunto Zoop Novo Dive Computer is concerned, it is built for entry level scuba divers.

As per the requirements of a beginner scuba diver, this computer comes with a big display screen so that the diver does not have to experience any difficulties in reading the information being displayed. Basically, the information can easily be read at a glance due to the size of the display.


Review Summary of the Suunto Zoop Novo Dive Computer

Experience Level

Designed for the new and less experienced divers.

STYLE

A oversized dive computer that can't be used as a daily watch.

Ease of Use

Easy to use navigation with separate buttons.

Price Level

Good value for the price. Priced as an entry-level dive computer.

We Like

  • Large and clean display
  • Simple to use
  • All features that an entry-level diver could need
  • Large log book to store dive information
  • Off Mode to take the computer out of dive mode completely
  • Personal dive profiles to adjust algorithm to be more conservative

We Don't Like

  • Too large to wear as a watch
  • No air integration

Summary:

The Suunto Zoop Novo is a great dive computer for beginners. However, that does not mean that an experienced diver couldn't use this computer. It is easy to use and has a whole list of functions that benefit the entry to mid level diver. Features that you would expect in a higher end scuba computer are not offered and there's also no possible expansion like air integration, etc. Needless to say though, for the price it is a great device.

Suunto Zoop Novo - Blue

You will notice that the display is quite clean as it is not stuffed or bombarded with strange abbreviations that beginners might have a hard time understanding. There are lots of dive computers with advanced information displays that are better suited for professionals.


The Zoop Novo is available in three different colors:

  • Black
  • Lime
  • Blue

​It is shaped like a regular watch but it is too large to be worn as a wrist watch. The large size makes it easier to read under water so it's a trade off that a beginner might not be too concerned with.




Capabilities

The Zoop Novo looks like a wrist watch but it is way too big to be used as one. The benefit of this large size is that the screen is capable of cleanly displaying all necessary data at a glance. It can work with five different dive modes:

  • Air
  • Nitrox
  • Gauge
  • Freedive
  • Off Mode
Suunto Zoop Novo - Lime

​The Zoop Novo is designed in the form of a wrist watch but is way too big to be worn everyday. The large size does allow for a very clean layout of the display though which makes it specifically for beginners very easy to read the information.

All important and necessary information is visible on the screen and the four buttons allow for easy navigation and adjustment. The battery level is clearly visible to prevent you from running out of battery while diving.

The navigation on this device is made as simple as possible for beginner divers. The buttons are ergonomically placed and allow to navigate through the different options even when using thick gloves. Compared to models with one button the navigation can be faster if using more buttons as you won't have to step through every screen option with a single button.

This device has audible and visual warnings for a number of conditions:

  • Dive Time
  • Max. Depth
  • Ascent too fast
  • High pO2
  • Decompression ceiling violation
  • Deepstop violation

Technical Capabilities

The Zoop Novo can handle oxygen levels between 21% and 50% in Nitrox mode. The pO2 limits for this device can be adjusted between 1.2 and 1.6 bars.

The maximum operations dive depth is 80 m (262 ft). It also features altitude adjustment settings up to 3,000 meters (9,843 ft).

As one would expect the algorithm is Suunto's own. It's an RGBM (Reduced Gradient Bubble Model) algorithm. It has been developed together with Dr. Bruce Wienke.

A really interesting feature of the Zoop Novo is its ability to allow the diver to adjust the conservatism of the algorithm. This allows to increase the safety levels for a dive if you want that extra level of safety. You can set the adjustment and this way set a more conservative dive profile.

Another cool feature is the off mode. This allows to prevent the dive computer from automatically switching into dive mode when it's taken into water. This can help to safe battery life if you wear the device without needing it.​

Dive Log and Connectivity

​The log in the device can hold data for up to 140 hours. For typical usage this should be enough for around 100 dives. The sampling time can be set at either 10, 20, 30, or 60 seconds. This provides a comprehensive logbook of your past dives.

With the separately sold USB connector and the software (for Mac and PC) you can easily analyze and alter the dive information. You can then upload the dive data to the Suunto Movescount portal. There all exercise data from all Suunto exercise and dive computers can be stored and retrieved. The portal allows to even add photos and videos to your dive data.

Missing Functionality

There certainly is functionality missing in an entry level dive computer like the Suunto Zoop Novo. The most obvious functionality missing is the lack of a compass. Typically, this can be found on higher end models.

There is also no air integration capability. Recreational divers will not really miss this feature but more experienced divers will miss it. It does unfortunately mean that the scuba computer will not fit your future requirements. Assuming that it will take the average diver a few years before needing a feature like that it's in reality not that big of a concern.​

Features/Specifications

  • Easy to learn 4 button navigation
  • Alarms both audible and visual
  • Large and cleanly divided display that provides all important information at a glance
  • Five dive mode settings for Freedive, Off mode, Air, Nitrox and Gauge
  • Nitrox settings between 21% and 50%
  • Limits for PO2 between 1.2 and 1.6 bars
  • Suunto full continuous decompression RGBM algorithm
  • Maximum operating depth 80 meters/262 feet
  • Three adjustable altitude settings up to 3,000 m (9,843 ft)
  • Imperial and metric display options
  • Dive log up to 140 hours
  • User replaceable Lithium battery (CR2450)
  • Available in three different colors
  • 2 year limited warranty

Pros and Cons

The Zoop Novo is a solid dive computer for the beginner to mid level diver. It features a sturdy build and has a great display. Suunto is the market leader so you know you get a great dive computer for the money. You won't find some higher-end features that you might miss when you are a more experienced diver. However, the Suunto Zoop Novo is a solid choice for a beginner or even for a medium experienced diver at a very reasonable price.

Pros

  • Easy selection through 4 different buttons
  • Suunto's proven RGBM algorithm
  • Four different dive modes (Air, Nitrox, Freediving and Gauge)
  • Can connect to the PC/Mac through USB connection
  • Great entry level product that delivers all needed functionality

Cons

  • No compass
  • No air integration
  • Not a wrist watch

The functions offered by this computer are in line with what one would expect considering that it targets the entry level market. It covers the bases without adding features that higher end devices require, e.g. Compass, etc. Unfortunately, it also does not allow to later on be extended with air integration. At that time it simply can't grow with the diver's additional needs and would have to be replaced if air integration became a requirement. However, that is a big 'if' and as such we think that it's not that big of a deal that this capability can't be added later on.

Where to Buy?

You can find the best price and service when buying the Zoop Novo from Amazon. They have all the available colors and also have bundles with the USB connector if you're interested in that. You also can be certain that you do get the genuine product and not some knock-off from Asia!

Customer Feedback

Checking the customer reviews and star ratings of the Suunto Zoom Novo quickly shows that everybody who purchased it is very satisfied. There's not really any complaint to be found.

Conclusion

This device is equipped with all the features and capacities that are essential for making the diving experience easy and safe. The necessary data is very easy to read and is readily available with this diving computer. With a bright and easy to read interface, it displays all the key information in a very simple manner. More importantly, unlike other beginner level diving computers, it has five operating modes which is a huge improvement if we compare this product with other similar product offerings in the market.

It does not pack all the features one would expect from a high end scuba computer. If you need the bells and whistles then you want to look at other, more expensive devices that suit your need.

Whom is the SUUNTO Zoop Novo not for?

​A more experienced diver will need more features than the ones offered with this dive computer. It will make more sense in that case to look at dive computers like the Suunto D4i Novo. This dive computer is a mid-level devie that can grow with your requirements as you gain experience.

The Suunto Zoop Novo has all the features you want in an entry level dive computer. The only issue might be if you want a device that can be used as your day-to-day watch. In that case you might want to have a look at the Mares Smart.

Cressi Leonardo Dive Computer Review

​Dive computers are used by many or nearly all scuba divers today. They replaced the complicated dive tables through the years and gained capabilities with every new model coming out.

The Cressi Leonardo is no exception to this. It's a powerful dive computer in a watch casing that is targeted mostly at the beginner market. It is designed and produced by Cressi, an Italian dive gear company that's been around since the 1930's.


Review Summary of the Cressi Leonardo Dive Computer

Experience Level

Targets the beginner level diver.

STYLE

A stylish dive computer designed like a wrist watch but it's too large to be worn every day.

Ease of Use

Simple to use, one-button navigation.

Price Level

On the lower end of the price spectrum as expected for a entry-level product.

We Like

  • Great display
  • Ease of use
  • All dive modes required for a beginner.
  • Reasonably sized log book

We Don't Like

  • Too large to wear as a watch
  • Backlight could be stronger

Summary:

The Cressi Leonardo is a fantastic entry-level dive computer. It offers many features that are sufficient to beginner and medium experienced divers. It is missing, as to be expected, features that can be found in dive watches that are targeting the experienced divers.

Cressi Leonardo Dive Computer - Black/Orange

The Leonardo is the first dive computer that is completely designed by Cressi. Evaluating the device shows that Cressi designed a great entry-level dive computer.


It comes in a variety of color combinations: black/grey, black/orange, black, black/blue, black/pink, blue, black/green, black/yellow, white/black, white/pink and white/lilac. It is however too large to be worn as a casual watch. You might be able to us it as a wrist watch if you have a large wrist.




Capabilities

The Leonardo comes in the style of an oversized wrist watch. Due to its size it can display a lot of data at one time on the screen. It is capable to work with three different dive modes:

  • Air
  • Nitrox
  • Gauge
Cressi Leonardo Dive Computer - White/Pink

​The display on this scuba computer is oversized and this allows to see all necessary information like time, mode, etc. The only downside is that the backlight is unfortunately is not that great which makes it hard to read the information when it gets murky and dark.

It will supply any wanted information on depth, dive times, decompression status, ascent rate and surface interval times between dives. In addition it displays the battery status to ensure that you can switch out the battery before you run out of it.

The one-button menu navigation is simple — press to toggle or advance; hold to enter menus or select. Since it moves in only one direction, you sometimes have to do a fair bit of pressing, but even the newest diver won’t get lost in the menu.

There are audible and screen warnings for deep and safety stops (although no safety-stop timer) and for approaching deco. An ascent-rate indicator uses an ascending stack of arrows to get the point across, and there’s an oxygen-toxicity bar graph and alarm. The audible alarms are designed to be loud enough to ensure that you can hear them.

Technical Capabilities

The nitrox levels for this dive computer can be set for oxygen levels between 21% and 50%. The PO2 limits can be set between 1.2 bars and 1.6 bars.

The operational maximum is 120 meters/393 feet. The Leonardo is capable to be adjusted to altitudes up to 3,700 m / 12,139 ft.

The algorithm is Cressi's own RGBM (Reduced Gradient Bubble Model) and is based on the Haldane model. Cressi modified the Haldne and Wienke algorithm as a basis of their own.

This algorithm allows for safe decompression calculations for multiple dives spread out over multiple days. Nitrogen absorption and release is continuously processed by its sophisticated software, taking into account the quantity of inert gases in the different mixtures which can be used. The Leonardo in addition allows to set safety factors to make the algorithm even more safe dive experience.

The Cressi Leonardo can be completely reset after each dive. This makes it a great choice for dive shops that rent it out and need to completely reset the data after the computer comes back.

Dive Log and Connectivity

​The built-in dive log is capable of recording data for 60 dives (75 hours). The data during a dive is sampled every 20 seconds to provide a solid record of your historic dives.

The dive log can then be easily transferred to your computer with the help of a connection device. This device has to be purchased separately and allows to download all dive data to your computer. You can then alter that information to run dive simulations to plan for future dives.

Missing Functionality

As to be expected from an entry model like the Cressi Leonardo does not have all the functionalities like a higher end dive computer has it. One item that is missing is for example that there is no compass.

In addition the Leonardo does not have an ability for air integration. This will not be a big issue if you are a recreational diver or just beginning to dive. However, it will not allow to have the computer grow with your experience and increased functionality needs.​

It also would be nice to have a safety stop timer. Even though it features a safety stop alarm, it doesn't come with a timer to guide you in how long the safety-stop should last. Overall, not the biggest of issues but a nice-to-have.​

The last downside (not really a missing functionality) is that the back light of the display is not light enough. While diving in clear waters this is not really an issue but if it gets murky and dark you will need to have a strong backlight to see the data on the display.

Pros and Cons

The Leonardo is a good entry-level dive computer. To be honest, it's one of the best. It's well-built and it is reliable. It doesn't have all the bells and whistles you'll get when you buy a higher end model but if you are a beginner or you want a backup for your more expensive wrist computer then the Cressi Leonardo is a great choice.

Pros

  • Super-simple one button navigation and selection
  • Cressi's own RGBM algorithm
  • Safety factor settings which add to overall safety when diving
  • Multiple modes (Air, Nitrox and Gauge)
  • Easily connects to your computer (PC or Mac)
  • Solid product that is reliable and adjustable
  • Can be completely reset after each dive - making it perfect for dive shops

Cons

  • No compass
  • Backlight is not very strong
  • No air integration
  • No safety-stop timer

There's not much bad to say about this scuba computer. The only thing that could be better in this price range is that it could have a better backlight. The other two listed missing features are in all honestly nothing you could expect from a dive computer that is aiming the entry-level diving market. You'll have to raise your sight to the higher end models which are several times over the price of this gear.

Where to Buy?

One of the best places to purchase the Leonardo is at Amazon.com. The most  variety of colors can be found there. It's the leading online retailer in the world and you can trust that you get the real product at the best price.

It's also easy to return items to Amazon if they don't match or work for you. Smaller retailers and outlets often will also charge more than you'll pay at the largest online retailer.

Customer Feedback

Most customers that purchase the CRESSI Leonardo do not regret it at all. It's one of the highest rated and most sold dive computers available today.

There are rarely any complaints to be found. The few you can see are related to the backlight not being strong enough and that you have to get used to the single button navigation.

In low-light conditions the backlight is simply not what it could be. Typically, a diver that is new to the sport will not dive in dark and low-light conditions as you're probably better off doing that when you have gained some experience. However, it would be nice if this could be improved.

Using a single button to navigate through all the display settings might take some getting used to. When you get the hang of it, then it becomes super-easy to use. But initially you might have to take a few minutes to figure out how it all works in order to get satisfied with the usage patterns.

Conclusion

The Cressi Leonardo is a great choice for an entry-level dive computer. You might want to look at other models if you are an experienced diver as it covers the basics but doesn't come with all the bells and whistles.

Besides the missing functionalities it does what it's supposed to do. It helps you dive safer and within the limits. It is compact enough to be packed in your travel back but it's not small enough so it could be worn as a wrist watch.

The Leonardo might be too basic for some divers, and we wish it had a safety-stop timer and a stronger backlight. But it delivers what it promises at a modest price for new divers or those who want simplicity. The Cressi Leonardo is our best buy in this category.

Whom is the CRESSI Leonardo not for?

​As an experienced diver you might want and need more capabilities than the ones offered. You want to look at models like the Suunto D4i Novo instead which offer those features and are capable to grow with your needs.

Besides that there's not much to complain about with this scuba wrist computer. You'll be hard pressed to find a better entry level computer. If you prefer a watch sized device then you want to consider the Mares Puck Pro as an alternative.

Suunto D4i Novo Dive Computer Review

Since dive computers were introduced they gained more and more popularity. There are many models out there targeting all levels of different divers with regards to their experience.

The D4i Novo is a mid-range computer with all the features you’d expect as a medium experienced diver. It is made by Suunto which is known to produce high-quality dive equipment and personal dive computers. Suunto was founded in 1936 and makes a range of dive gear.

Summary:

The D4i Novo is a great every-day dive computer that can be worn as a dive watch. It offers everything you can ask for in a mid-range diving computer except for a compass.

Suunto D4i Novo

The Suunto D4i Novo is the follow-up model of the successful D4i dive computer. Looking at the technical specifications shows that there’s basically no difference between the two models.


Its updated design allows to wear it as a dive watch. It comes in a multitude of different colors: black, white, blue, grey, lime, ocean, pink, sakura and sun. It can be worn as a casual watch.


Besides the different colors, the biggest difference to the D4i model are the soft silicone straps and that the buttons are made of metal instead of plastic. The new straps ensure superb comfort and ensure a perfect fit.



Capabilities

The Suunto D4i Novo is a compact and lightweight dive computer. If features four different dive modes:

  • Air
  • Nitrox
  • Free-Dive
  • Gauge
Suunto D4i Novo Pink

Additionally, an optional wireless air transmitter can be purchased and connected to monitor the tank pressure and keep track of air remaining on the display. This air integration has to be purchased separately and the transmitter is added to the regulator first stage. The optional integration will typically not be necessary for an entry level to medium experienced diver. It does however provide the ability to increase its capabilities to grow with the experience level of the diver that owns it.

The display on the D4i is sufficiently large. It is a dot matrix display with a strong backlight. The watch screen shows the essential information including current and maximum depth, dive time, decompression time and current time as well as the temperature. It’s not a color display and it certainly doesn’t have to be!

When using the dive computer in free diving mode, it will sample the depth three times per second to provide an accurate real-time depth reading. This allows to store and track a free dive in the computer.

To keep the diver safe, the dive watch offers both audible and visual alarms for safety stops and depth as well as for time. This provides clear signals when to start the ascent.

Technical Capabilities

The computer allows to program nitrox mixes with oxygen levels between 21% and 50%. The PO2 limits can be set between 0.5 bars and 1.6 bars at the same time.

Its operational depth display ranges from 0 to 100 meters/0 to 328 feet. In Gauge Mode it will display and function down to depths of 150 meters/492 feet. The D4i is also altitude adjustable up to 3,000 meters/10,000 feet.

The algorithm used is based on the Suunto Reduced Gradient Bubble Model (RGBM). It is based on laboratory data as well as diving data. Suunto developed it together with Bruce R. Wienke and it is one of the best and most modern algorithms available. It allows for safe dives as it predicts dissolved and free gas in the blood and tissue based on depth and time under water. It’s a reasonably conservative algorithm that makes sure that recreational divers stay within their limits.

Dive Log and Connectivity

The D4i has a built-in dive log that is capable of recording up to 140 hours of dive information. It can be exported to your computer (both Mac and Windows) and then can be uploaded to the Suunto Movescount portal where you can track all your exercising from all Suunto watches including their dive computers. You can even add photos and videos of your dives to the uploaded log books to share with others.

The portal also allows to plan future dives based on historic data. Dive data from the log can be analyzed in depth and displayed in charts. This allows to make better choices and adjust alarms and dive times for future dives.

Missing Functionality

What is missing in the Suunto D4i Novo is a digital compass. This is provided in the next model up, the D6i Novo. It’s one of the features that can rarely be found on any mid-level dive computer so it’s not like the D4i would be the only mid-range model that doesn’t have it.

Another small downside is that the buttons can be hard to handle when diving in cooler water with thick gloves. This is overall an issue with any watch-style dive computer. Due to the size of the computer the buttons can simply be too close together when trying to press them while wearing thick dive gloves. This issue typically is not an issue when wearing no gloves or thin ones or when you have small hands.

Features/Specifications

  • Easy to use with only 4 buttons
  • Adjustable alarms for ascent rates and maximum depth and time
  • Free diving mode sampling depth information 3 times per second
  • Clear and precise dot matrix display with backlighting
  • Four dive mode settings including Air, Nitrox, free dive and gauge
  • Adjustable Nitrox settings between 21% and 50% with PO2 limits between 0.5 and 1.6 bars
  • Maximum depth display to 100 meters/328 feet
  • Adjustable Altitude
  • Both imperial and metric display options
  • Built-in dive log up to 140 hours
  • Lithium battery (CR2450)
  • RGBM (Reduced Gradient Bubble Model) algorithm
  • Built-in dive planner
  • Available in different colors
  • Compact design to be worn as an everyday watch
  • Optional wireless air integration
  • 2 year limited warranty

Pros and Cons

No product is perfect and the Suunto D4i certainly isn’t either. However, it is a great dive computer for the money and suits entry level as well as medium experienced divers well.

Pros

  • Compact and light design which makes it easy to use and wear even when used as a day-to-day watch
  • Multiple modes (Free Dive, Air, Nitrox and Gauge)
  • Optional wireless transmitter to measure tank pressure and display remaining air time on the screen
  • Simple 4 button usage with clear and backlit dot matrix display
  • Easy connectivity to computer through included USB cable and extensive upload and log capabilities when using in conjunction with Movescount.com
  • Safe and reliable RGBM algorithm
  • Easy adjustment of the strap to ensure a tight and safe fit

Cons

  • No digital compass
  • Not easy to use when thick gloves are worn
  • Battery has to be changed in a Suunto service center

The pros and cons clearly show that there’s not much negative to say about the Suunto D4i Novo. It has a lot of features for a mid-range dive computer and anything more than that would actually put it into the high-end category.

Where to Buy?

The easiest and typically cheapest way to purchase is through Amazon.com. You will find the widest variety of colors and prices there and you can trust the largest online retailer. If the dive computer shouldn’t suit your needs then it’s easy to return at Amazon.com. Smaller retailers and dive shops might charge more in the first place.

Customer Feedback

The overall feedback that can be found online and in forums is absolutely positive. People that purchased the SUUNTO D4i Novo are happy with the product and there’s barely anybody who has a complaint besides what was already mentioned in the cons above.

Besides that the only other complaint is that the battery can’t really be changed without bringing or sending the dive computer to a service center. This can be a major hassle when you want to use the dive computer just as the battery warning comes on.

Many people use this dive computer as their day-to-day watch. It’s compact enough and comes in such a large variety of colors that anyone can use it exactly as that.

Conclusion

The D4i Novo is a well-rounded dive computer that provides nearly every capability you might need. There's only one functionality you might be missing which is the compass but that will not necessarily be a problem if you are a recreational diver.

Other than that it simply fits the bill of what the beginner to medium experienced diver would need and expect from a dive computer. It is a reliable piece of dive gear that can easily be worn as an everyday watch.

One big plus is that the dive watch can grow with you. If you’re a more experienced diver and you’re going to do more sophisticated dives that require air monitoring. Adding the optional wireless transmitter allows to do just that. At that time the D4i Novo basically upgraded to the semi-professional level.

Whom is the D4i Novo not for?

If you are already a truly experienced diver requiring more capabilities of your dive computer then you should consider the Suunto D6i Novo instead.

Suunto is one of the leading manufacturers of dive gear and dive computers. They also have a wide range of exercise watches and a stellar reputation.

The D4i Novo is the redesign of the D4i and Suunto did a great job with it. They improved on the straps and made it overall more modern looking. If these are things you don’t put any value on then you might want to check out the D4i itself. You can get it cheaper and with basically the same capabilities.
