Best Dive Computers for Beginners – Buying Guide and Reviews

One of the first pieces of equipment that a beginner diver nowadays needs to get is a scuba diving computer. Not too long ago it was getting printed dive tables but as capabilities have increased and prices have decreased, a solid dive computer has become essential for a new diver.

How to find the best scuba diving computer for a beginner diver

We’ll guide you through the considerations you need to keep in mind to find the best dive computers for beginners and show you our best choices.

Best Beginners Dive Computers – What a Beginner Diver needs to know!

Eager, first-time divers, want to know everything about their newfound hobby.

We’ve got the scoop for you on everything you need to know about dive computers. A dive computer is your digital lifeline, allowing you access to real-time information for the perfect dive.

In a hurry?

Here are our suggestions for the best dive computer for beginners:

  1. Cressi Leonardo
  2. Suunto Zoop Novo
  3. Mares Puck Pro Plus

When you are looking to buy a new dive computer that is suitable for beginners then you should be aware of the features that these dive computers should offer.

These standard features include

  • Depth
  • Time
  • Emergency decompression
  • Ascent rate
  • No stop time remaining
  • Previous dive information
  • No stop limits
  • Low battery warning
  • Enriched Air/Nitrox compatibility

There are a number of features you will not find in a dive computer for beginners. These range from a digital 3D compass to Trimix/Air/Nitrox gas switching while diving, etc. Having said that, these functions are also not necessary and will only make it harder to work with the dive computer during your first years of diving.

Quick tips for purchasing a dive computer include:

Navigation is Critical

When going diving you need to have a good idea where you are and where you’re going underwater. Having supporting equipment to help with navigation is important for your safety.

The more pressure you find yourself in, the more disorienting it can be. No matter how much you think you know, under the water is another story.

Navigation is critical and owning a dive computer with an old-fashioned compass is pivotal in your safety. Without this, you may not know how to get to shore, or back to your boat for safety.

Life-Saving Depth Gauge

Without the life-saving component of a depth gauge, you may wander a little too far down to where you’re too disoriented to function and ask for help.

A depth gauge works hand in hand with your decompression stops and calculates how much time you spent at a particular depth. If you’re left guessing, it will negatively affect your calculations for decompression stops.

The Perfect Calculations

When you’re at a low depth, it can be hard or near impossible to make any calculations yourself while functioning in the water world around you.

A beginner diver will not dive with enriched air anytime soon. However, eventually, you might come to the point that you will do that and it’s definitively an advantage if your dive computer can handle air/nitrox gas mixes.

Dive computers take out this stressful aspect for you and perform the calculations for you. These life-saving calculations work alongside decompression calculations, decompression stops, and specific dive computers that offer calculations of no-fly times for those who are diving on vacation.

It sounds morbid, but when you ascend in a plane after diving into a certain depth, the nitrogen in your body will expand because of the pressure. You may explode! (No, seriously, it’s a thing and you need to adhere to some safety precautions). Some dive computers will let you know when you can safely fly again.

On-Board Memory

Most modern dive computers will have an onboard memory feature for you to review all the information stored away during your ascent into the aqua world. It’s a nifty little feature and can help you predict and plan for future trips down.

Activation of Your Dive Computer

Any dive computer bought will have to go through an activation process, much like a phone. Thankfully, you don’t have to activate your phone with water, though!

Automatic Activation

There are two ways to enable a dive computer for beginners including manual or water activation. The manual option requires the diver to press a button on the dive computer before going in the water.

If you’re new, I should forewarn you that many divers FORGET this aspect of preparation, causing companies to come up with a solution that allows instant water activation on their dive computers as soon as divers are in.

Best Dive Computer for Beginners

Now that you’ve got the scoop on the different life-saving and data recording components, we’ll go over our top three picks (and our top recommendation!) for the best dive computers for beginners.

#1 – Cressi Leonardo – Beginner Scuba Computer from Cressi

Not overly clunky and super fashionable, the Cressi Leonardo dive computer is one of the best on the market. Its design is sleek and not bulky/heavy, so you won’t worry about it in the water constantly, with features that include:

  • Audible alarms
  • Easy on button
  • Dive modes Air/Nitrox
  • Large digits for better reading underwater
  • Backlit screen for night dives

Not only does this dive computer give you a readout for the different depths during your dive, but you can also read these numbers with no issues at night. The backlit screen on this dive computer function allows for safe tracking during dangerously dark dives.

Data Reset for Rental Shops

Diving with the Cressi Leonardo or the Suunto Zoop Novo

This dive computer also has a data reset feature, which is perfect for rental companies working with beginners. This may be the only downside, as beginners may accidentally stumble into this section and delete their hard-earned data.

Another significant aspect of this computer dive watch is the audible and visual automatic safety stop countdown at 15 ft or 3 minutes. A wrist-held safety buddy, there’s no real reason you shouldn’t purchase this as a beginner! This dive computer has a 24-month limited warranty.

#2 – ​Suunto Zoop Novo – Suunto’s Entry-Level Scuba Computer for Beginners

The Suunto Zoop Novo is the successor of the Suunto Zoop dive computer. It’s gotten a little bulkier and has several added features and functions compared to the first version of entry-level wrist-mounted scuba dive computers by Suunto.

Easy Navigation

The size of the dive computer is overall easy to manage and navigation is super easy with four dedicated buttons placed around the display.

Both other dive computers we listed in this guide, the Mares Puck Pro Plus and the Cressi Leonardo, have a single button for navigation. At first glance, this is an easier design, but it has a disadvantage.

Single-Button Navigation – Not on the Zoop Novo

If you page through the different menu options with a single button you have to step through each option as you cannot go back and forth with a single button. A dive computer design with multiple buttons lets you go back and forth as needed.

It can make it easier to get to where you want to be in your menu options. Having a single button simplifies the overall handling but can make it a lengthy process to get where you want to be in your navigation options.

The Zoop Novo is the entry-level dive computer for beginners by Suunto. It comes in different mounting options with the standard variant being a wrist-mounted design but there are also versions where you can get it as a console-mounted device. The overall features are targeting divers that only need the basic set of features and functions:

  • Air/Nitrox/Gauge/Freedive/Off modes
  • Audible and visual warnings and alerts
  • Four-button navigation
  • Large display with all data at-a-glance
  • Large log book with up to 140 hours of data

This is a no-nonsense beginner scuba dive computer with all essential features and functions for a new scuba diver. It’s easy to use and makes it easy to read the information on the display. The backlight is strong enough to allow you to read the data on the screen in dark and murky waters.

Conservative Algorithm

The computer uses Suunto’s own RGBM algorithm. This specific algorithm is seen as rather conservative. You can adjust the algorithm if needed, but that only allows you to make it even more conservative.

Suunto DM5 Software to analyze dive data

The Suunto Zoop Novo is a great scuba dive computer, and it’s hard to find real negatives about it.

You won’t get all the bells and whistles of a higher-end scuba diving watch but that’s what you’d expect from an entry-level device for a beginner. It offers all the required basic features and you’ll be diving for a while before you look at any higher-end functions in your dive computer.

#3 – Mares Puck Pro Plus – Bluetooth for Divers

The Mares Puck Pro Plus is the latest rendition of the original Puck scuba diving computer. In case there’s any confusion about the name, it refers to a hockey puck regarding shape and size.

Wrist Mounted – Puck Sized – Mares Style

You can find many other wrist-mounted scuba dive computers that are smaller or that you can even wear as your daily watch. If that’s your criteria then the Puck Pro Plus is not the best dive computer for you!

Features of the Puck Pro Plus

It’s designed as an entry-level scuba dive computer for beginners that provides all the basic features you would expect and need:

  • Dive modes Air/Nitrox/Gauge
  • Visual and audible alarms
  • Single-button navigation
  • Clear and easy to read display
  • Bluetooth connectivity

Bluetooth connectivity

The biggest improvement Mares had in store for the Pro Plus dive computer is the Bluetooth connectivity. No more cables required to exchange dive data with your PC!

Diving with a wristwatch sized dive computer

The display received a few minor changes and is as excellent as it has been on the Puck Pro. Large numbers that make it easy to read combined with a strong backlight so you can still see all information in dark environments.

The Mares Puck Pro Plus is a solid choice for beginner divers with all the necessary features and functions like air and nitrox handling you’d expect from an entry-level scuba computer!

Best Beginner Dive Computer – Final Thoughts for Divers

We think the best dive computer for beginners is the Cressi Leonardo.

While the version with the stand and USB connector is nice, it’s not a necessity. You might as well save yourself some money and go with the basic model without all the connectivity items.

You’d thought we would recommend the last of the dive computers listed above? While the added features are helpful, they aren’t essential to most dives and scuba divers, and you can get those higher-end features with a more complex device at a later time.

For beginner scuba divers, it’s important to feel out the piece of equipment instead of splurging on the biggest package possible. If you enjoy this watch and want those added features of a download cable and stand, those accessories are available online.

For beginners, this watch is fantastic. With large fonts, sounds, and all the readings you can hope for no matter the time of day, the Cressi Leonardo hits the nail on the head.
