This is a great computer. I bought a second Cobalt2 as a backup computer. I still wear a wrist computer but the display is brighter and easier to read in all lighting conditions than any wrist computer. While I would prefer to have replaceable batteries versus rechargeable models, the only problem I ever had with my original Cobalt2 was with the charging adapter plug, not the computer. The computer uses a quick disconnect cable and logs many dives. I have over 100 dives on my first Cobal2. I highly recommend this computer.

Did my homework and selected this unit. Its not my first one. Went on a cold water dive and when I surfaced noticed that water was inside the unit. Sent it in to my dive center and it was sent to the company. I actually received a phone call from the technician working on it and he stated that he had never seen a malfunction like this. I had had the unit for 2 years without an issue. Obviously it was out of warranty but since it was definitely a first for the company to see something like this, they replaced the whole unit without questions.

I've had the computer for about 20 dives now and it has worked flawlessly. It's very, very easy to setup and use. Easy to understand, intuitive nature, you barely have to read the instruction booklet. My only concern is that some of the smaller info on the screen is a bit difficult to see underwater, but not a real concern; otherwise I would have given it a 5 star review. I have a lot of equipment from Atomic Aquatics and this is just another example of their extremely high quality work.

I bought the atomic because I wanted to buy a backup computer to dive watch. It worked flawlessly. I like that it is probably the easiest computer in the world to use. It has all the features almost any diver can need. My only complaint would be the compass is too small. I am a 55 year old guy and it was hard for me to see. In all fairness I have only had it diving for one week and I will post a long term review once enough time has happened.

I love this computer! It was an open box deal and I feel like it was a steal. Since using the dive computer I have becom nitrox certified it is so easy to switch! Thank you LeisurePro for the recommendation.

I'm a marine biologist and spend a lot of time underwater, day and night. I've used this computer throughout the Pacific with only occasional rinses and it has worked perfectly as advertised. Probably the best feature is the 4 button nav system, and extremely well designed software. Without using the manual at all you will be able to set this computer up in a few minutes, and reconfigure, switch units, switch gases etc underwater once again simply and without a manual. I design computer interfaces- the Atomic crew has done an amazing job here. The screen is bright with large digits, which I need as I use reading glasses on land. The quick disconnect is an exceptional piece of engineering. It takes a while to charge, and does not do that many dives on a charge (10 or so?), but it is trivial to plug in and charge after each days diving, either to a socket or a laptop USB port. You just give it a rinse and a shake and plug it in. Best computer I've owned, and over my professional career I've owned a lot.

This computer would be amazing if it worked. It completely died after less than ten dives.

My original unit had a pressure sensor issue in that it showed the pressure 400 psi low. Replacement unit (different serial number) came with no firmware on it. I had to download and install. It worked for ~100 dives and then went dark again. After reloading firmware again, now the BACK button will not work so I cannot get past time/date screen.

I've owned my Cobalt 2 for 20 months. During this time, I sent the computer back to Atomics twice for failure of the pressure gauge. I now need to send it back again, since it now sounds the low air alarm after the dive on the boat. Very embarrassing, since it goes on for a good time.

I have had 2 different Cobalt 2's in the last 17 months. Both have been sent back to the factory and needed to be replaced. I don't trust my 3rd one and I am currently working with my local dive shop to return it with the suppliers agreement for credit to the shop. Software is difficult to print as you can only get the profile and not all of the personnel added info that you add to each dive. I've read many other reviews with the same issues. DONT BUY!

Easy to See, Simple to Use, Brilliant LCD Display:
The Cobalt 2 is the newest release of Atomic Aquatics new generation of dive computers that are easy to use, easy to read and totally intuitive. The Cobalt 2 features a newer more powerful microprocessor, faster compass response and new user options such as auto screen brightness. User selectable gas switches are increased from 3 to six mixes. The menu driven display is self-explanatory at every level and can be mastered in just a few minutes. This simplicity is in contrast to its powerful capabilities and the many advanced user functions available to those who wish to use them. In addition, it uses a rechargeable lithium ion battery that will give the diver between 40 and 60 hours of dive time per charge and a charging adapter that gives the user the option of USB or AC sources.
Brilliant full color Organic Light-Emitting Diode (OLED) display provides the high contrast, sharpness and brightness that can be viewed at almost any angle. The upgrade for smoother more responsive on-board 3D digital compass makes underwater navigation simple. Set a course and go, unlike most digital compasses, it will remain active until you choose to turn it off. The Cobalt includes a high-pressure quick disconnect that allows the Cobalt to be removed and carried separately from your regulator system. The Cobalt is a multi-gas computer that can be set for any Air/Nitrox mix to 99% O2. Up to 6-mixes can be preset for easy switching, including gas switches underwater. The dive log and planner are powerful tools that allow the easy interactive planning of almost any dive, including repetitive and multi-day diving. The logbook will store up to 600 hours of detailed dive profile's in memory. The algorithm used in Cobalt is the recreational RGBM (Reduced Gradient Bubble Model) created exclusively for Atomic Aquatics by Dr. Bruce Wienke. The RGBM is designed to cover a wide spectrum of diving activities such as bounce, altitude, decompression, repetitive and multi-day. RGBM is a dual phase model that combines the dissolved phase (Haldane) and free phases (bubble). physiological factors such as age and exertion level may be input by the user. Additional settings are also provided to set the conservatism level.
The OLED display measures 2.4" (61mm) with overall dimensions of the computer (L x W x D) 6.5" x 2.6" x 1.4" (16.5cm x 6.6cm x 3.5cm) and weighing 11.2 oz. (317 g) making for a lightweight, sleek compact design. The computers quick-disconnect hose is a 5/8" (8mm) Kevlar reinforced slim-line design with 7/16" threaded end. The Cobalt Computers operational depth is 330' (100m) with an air pressure display of 5,000 psi (344 bars). Computer has a 12/24-hour time display with date function, temperature function, is automatically altitude adjustable to 10,000' (3,048m) and can be set for imperial or metric measurements. The Atomic Aquatics Cobalt Air Integrated Air/Nitrox Dive Computer comes with a full color comprehensive owner's manual, AC charger, USB cable, USB/charger adapter and compass calibration tray.
