Oceanic OCi Dive Computer Review
This wrist watch style dive computer by Oceanic is great for new and experienced divers alike. The Oceanic OCi dive computer is a wristwatch style computer. It features 4 buttons that allow you convenient on-screen navigation. The display is large enough to be seen under water, and the backlight works well at depth to illuminate the display. Some may find the display is a little too small compared to the larger touch-screen style dive computers.
The optional wireless air integration makes this an excellent moderately priced dive computer. The wireless air integration limits the hoses that you will have surrounding you making your dive seem less cumbersome. With 4 air mixes and nitrox optional, this dive computer allows even those who prefer deeper dives or higher percentages of oxygen to utilize a moderately priced dive computer.
Has everything a new diver needs and everything an experienced diver wants.
Watch sized to be worn all the time yet a little bulky if you have a small wrist.
Ease of Use
Navigation through four buttons.
Moderately priced. Optional wireless integration adds to price if required.
- Can be worn as an everyday watch
- Hot battery swap, retains data
- Air integration optional
- Dual algorithm
- 4 air mixes
We Don't Like
- Battery replacement needs pressure testing by dealer or factory
- Small digital display
- Small log book contains only 24 dives
The Oceanic OCi scuba diving computer is a fantastic midpoint dive watch. It comes with almost everything that you would need including air integration and battery hot-swap. Though the watch may be a little bit bulky for small framed people, it can be worn everyday for those who prefer to wear only one watch for all purposes. This makes it very convenient when tracking altitude and flight times.
If you’re looking for a watch with a large memory, the OCi is not going to be the watch for you. It only stores 24 dives at a time before you need to upload your dives into your dive log. A long diving trip may require that you download your dives while still on the boat.
Altogether this device is perfect for the average diver. New divers are going to find that this has more features than they will probably use. More experienced divers are going to see that this watch by Oceanic has everything that they need. If you require an LCD screen or larger display you may want to look at a higher pricepoint watch.
While we overall like that a dive computer can be worn as a wrist watch, in this case we're not certain about it. The device offers so much functionality that it feels like a large screen would be beneficial.
However, the display is easy to read and clearly setup. The navigation is performed through four buttons and it's easy and intuitive to step through the menu choices to get where you want to be.
The OCi comes in a variety of color choices:
When looking at the Oceanic OCi, you’re going to find it has many features. Oceanic claims that the “I” stands for incredible. That’s not far from the truth considering the pricepoint for the watch and the features that are available.
It offers four different dive modes:
- Norm (Air and Nitrox)
- Free Diving
- Tech Free Dive
You can activate the watch with the push of a button or use the water activation system included on the watch.
The maximum depth for the Oceanic OCi dive computer is 180 m or 495 ft when working in the gauge or free dive mode. When working in the normal operating mode, the maximum depth is 330 ft or 100 m. There is a deep stop with countdown timer allowing you to see your multiple safety stop times without difficulty. The optional two countdown timer for deep dives is half maximum depth for dives 80 feet or greater.
There is both temperature display as well as compass included on the Oceanic OCi dive computer. The other displays include air time remaining, nitrogen tissue loading bar graph, oxygen loading bar graph, no decompression time remaining, air time remaining, and O2 times. This allows you to customize your display to your personal preference.
The backlight on the Oceanic OCi is automatic and uses the OceanicGlo backlight technology. The time that the backlight is on is adjustable by the user. This allows you to maximize the life of the battery by limiting the backlight time.
The OCi dive computer uses the CR2450 battery, and the transmitter uses a 3.6V CR2 battery. The battery life for the dive computer is 300 hours, and the transmitter has a battery life of 1500 hrs. Hot-swap is available on the Oceanic OCi dive computer allowing you to retain all dives when changing the battery. There is a low battery indicator, which is a graphic display on the dive watch. The only downside to the battery options on the Oceanic OCi dive computer is that the manufacturer recommends pressure testing by either the dealer or the factory when replacing the battery.
There are several alarms available on the Oceanic OCi dive computer. You can set:
- dive time remaining
- maximum PO2
- free dive elapsed dive time
- free dive countdown timer
There are also high O2 and high PO2 alarms as well as your normal alarm clock and safety stop alarms.
The Oceanic OCi dive computer allows you to display time in either 12 or 24-hour format. There is a calendar available on board as well as the 24-hour time to fly countdown. This easily allows you to track dates and times, especially when tracking flight information.
Oceanic uses exclusive dual algorithm technology to power the OCi dive watch. You can choose between the Pelagic DSAT (Spencer/Powell data basis) or Pelagic Z+ (Buhlmann ZHL-16C data basis) algorithms to get the most out of your dive.
The OCi dive computer has the capability to switch between four nitrox mixes. The mixes can go from 21 to 100% O2. The wireless transmitter has the capability to switch between four independent transmitters for the difference O2 mixes allowing you to easily swap tanks and dive without changing the settings on your transmitter or computer.
There is automatic altitude adjustments featured on the Oceanic OCi dive computer. The altitude algorithm basis is NOAA, as well as the O2 limit basis. The automatic altitude adjustment is 610 to 4200 m allowing you to rely on your Oceanic to safely prompt you for flight countdown and altitude adjustments.
Dive Log and Connectivity
The on-unit dive log of the Oceanic OCi dive computer has the capacity to hold 24 dives. Included with the dive computer is the Oceanic log computer PC or Mac download and upload settings.
The Oceanic download memory capacity is 1 MB total. You can connect your Oceanic dive computer to your Mac or PC with a USB cable.
The biggest feature that is missing from the Oceanic OCi dive computer is the lack of an ascent rate exceeded alarm. In addition to that, we also wish that the battery was user replaceable on this dive computer. Having to take the computer to a dive shop to be pressure tested to change the computer can be a hassle.

If you’re looking for a moderately priced dive computer that has everything you need to plan a dive, then the Oceanic OCi dive computer is going to be exactly what you need. It has all of the features you would expect from a more expensive watch like wireless air integration and battery hot-swap. But it doesn’t take up too much room because it still maintains the watch style wrist mount.
For being such a small dive computer, it has plenty of features. New divers are going to have everything they need and more. Experienced divers will probably find that this dive watch has everything they want. The multiple settings and display options allow you to program different dive settings for various dive environments. Making it easy for you to dive multiple locations without reprogramming your watch.
People who do not want to spend a ton of money for wireless air integration are going to really enjoy the Oceanic OCi dive computer because you can get a lot of features without spending a lot of money. The computer doesn’t take up a ton of space on your wrists, so it minimizes the bulk you carry around with you at depth. For the minimalist diver, this dive computer is going to be perfect.
Who wouldn't like it?
If you like to be able to view bar graphs and displays while underwater this watch is not for you. Those people who need larger LCD or OLED displays to be able to view their time at depth will dislike the small display on the screen. The four-button system can be frustrating for those who are used to touchscreen interfaces.
More technical divers may find that this computer lacks the appropriate displays they need or want. Without being able to display everything at the same time, like you would be able to do on a larger dive computer, technical divers may find that they just want a little bit more from the Oceanic OCi scuba computer. But for the pricepoint, it is exactly where it needs to be both in functionality and design.
