Oceanic Geo 2.0 Air/Nitrox Computer Watch

This dive computer is great for recreational diving! I am very happy with the purchase, and would gladly buy it again. I am a Rescue Diver, and do a lot of wreck and cavern diving down to about 130ft (many on nitrox). I dive 2-3 times per month, and have about 50 dives on this computer.I purchased this computer for its "Tec-reational" features, and because it is small enough to be worn as a regular watch. When I say "Tec-reational," I mean that you can set two different gas mixes, and switch between them underwater. This allows you to breath air or nitrox for your bottom gas, and then switch to an 80% or 100% O2 bottle on the way up. Also, the computer WILL NOT LOCK YOU OUT if it goes into decompression mode. Many computers will not allow you to dive for 24hrs after entering required decompression.My biggest gripe is that you cannot enter your nitrox mix, and then confirm that it was entered correctly. When you push "select" to save the mix, it takes you out of the nitrox menu. The only way to confirm your mix, is to go into a separate menu ("Dive Mode" > "Dive Planning") where the mix is displayed. This is actually a software glitch, because you can only plan a dive based on the mix that is currently set in the nitrox menu. I like that you can view your current PPO2 while in dive mode. Many computers do not allow you to do this.The menus are quirky to say the least! Many of the menus have a single letter for their title. For example, the title of the nitrox menu is "F." There is plenty of room on the screen to put a 5-8 letter title, like "NITROX" or "SET O2%", or anything. The menu to adjust your max allowed PPO2 is called "A". The menu to select the decompression algorithm and safety stops is called "U". I usually have to randomly try a couple of menus until I find the one I am looking for. Navigating the menus is actually quite simple (because of the 4 button design), I just with they had given them more intuitive names.The audible alarms are not loud enough to be heard underwater. I can only hear them if I bring the watch close to my head. But the red blinking LED alarm is a nice touch.This computer has a lot of features that are only found on computers twice this price. It is a great value purchase, and you can wear it as a regular watch to boot.

To be clear, this rating provided is more applicable to Oceanic and Huish Outdoors customer service, not the retailer or necessarily the operation of the Geo 2.0 dive computer. The retailer shipped the Geo 2.0 dive computer to me as advertised and in a timely fashion and after about 30 dives, I've had no basic operational issues with the dive computer itself. Although I have not yet learned or utilized all its stated capabilities.The problem I have is with product support from Oceanic (bought by Huish Outdoors in 217). I have requested product support from Oceanic sales and technical support on numerous occasions and again directly from Huish Outdoors more recently for the follow reasons:1) The user manual for the dive computer is for all intents and purposes is useless. You will find many such reviews on this. I typically do my homework before making a purchase online and I read the reviews about the poor quality of the user manual, but being a mechanical engineer that has been writing technical documents for almost twenty years, I understand that, on occasion, it can sometimes be a customers lack of basic understanding that contributes to their frustration. Not so in this case, the user manual is all but useless as training manuals go. I tried several time to contact Oceanic technical service through their web site as I had read that they would provide a code for access to free online training on the Geo 2.0 via divecomputertraining.com. Note its pretty telling that a third party has to offer basic training on how to use this computer. Oceanic has never responded any of my requests, not even to acknowledge they received a request, and that is what anyone researching dive equipment from Oceanic or Huish Outdoors needs to take away from this (also consider that under the Huish umbrella of dive equipment manufacturers is Atomic Aquatics, BARE, Liquivision, Stahlsac, Zeagle, Oceanic and Hollis). Some of these brandnames such as Zeagle have had a pretty solid reputation. But in this case not so much. So before you go out and spend hundreds of dollars on a dive computer (or anything else from Oceanic or Huish) you should consider that there may be no customer support if you have an issue. To me that is a significant consideration.2) Oceanic does not appear to have drivers for the Windows 10 OS, which are needed to install and use the Oceanlog electronic log book. There is no mention of Windows 10 drivers on the tech support page and, again, after numerous inquiries about where I could get up to date drivers, there has been no response at all. This I was not aware of this when I bought the dive computer and having the ability to use an electronic diving log is one of the primary functions I was looking for in the Geo 2.0. Also note that you will need to buy the USB cable separately and this is probably the most expensive USB cable you'l ever buy (about $100) for a USB cable, yes the very same cable you can get a Walmart for $5 but with the connector specific to the Geo 2.0. It is completely unreasonable to have to pay that much for a cable.So, consider these points before making your purchase. As for me, unless Oceanic/Huish does an about face on their customer service, I will not be buying any more equipment sold under the Huish Outdoors banner. To me, customer support matters as much as quality of the product.

The Geo 2.0 dive computer sits comfortably on the wrist, not bulky, can be used as daily wrist watch (comes with strap extender to use with wet or dry suit). The screen display does not have the same contrast as advertised in the product photo on website, it's bit dim and dark (see photo). The clear contrast, black lettering against clear white background, as advertised on the website was one of the main reason for me to choose this dive computer. I am not sure if this is the case in the unit I received or this is how all of them are, I am bit disappointed. However, optimum use of screen real estate, and relatively large display and lettering, make it easy to read, and four button operations is mostly intuitive. It took me about 10-15 minutes to set up the watch and dive mode with the help of few YouTube videos, but mostly common sense and familiarity with dive lingo. It comes with quick start guide, a CD, but I didn’t need to use either of them. It allows you to do some customization, e.g. selecting two air, nitrox settings, alarms, choice of two algorithms, conservative factor, deep stop, safety stop, and plan you dive, but nothing too complicated. Overall a good dive computer for beginners and probably advanced beginners. The strap & body is not completely black, but greenish. Considering the low price, features, and size, I’ll recommend it.
