As an all-purpose dive computer, you can wear it as a watch as well without any issues. Inside, it uses Oceanic’s proprietary Dual Algorithm. The configuration allows for you to choose decompression settings that fit your personal level of expertise.

Oceanic Geo 2.0 Dive Computer?

The Oceanic Geo 2.0 Dive Computer tracks your dives for up to 24 hours. If you’d like, you can transfer the information to your PC via the optional USB cable that is available for purchase. 

You can also see the stats from your last dive if you take advantage of the “last dive” function on your Geo. The dive computer also has a backlight that makes it easy to read as you become familiar with how the thing works.

The materials that make up the computer are clearly durable and still look nice, too. You may or may not have issues with reading the manual, but the Geo 2.0 is user-friendly, so it won’t take long to figure it out. The crew over at Scuba Living Dreams agrees that the menu is easy to navigate.

There are four different operating modes. They are Watch, Norm, Gauge, and Free Diving. Under the watch mode, your computer acts as a watch. Under the norm mode, you can adjust your air mix and monitor from there. The gauge mode runs with a timer in place to let you know how long you have been under water. Lastly, the free dive mode monitors your dive time and is an appreciated feature that not all dive computers have.

What Makes the Oceanic Geo 2.0 Dive Computer Unique?

The design of the Oceanic Geo 2.0 Dive Computer is fantastic, and it looks just like a watch, too. As a scuba diver, you can wear it with pride, and other people that know what it is will absolutely notice. As such, your dive computer will function as an equally impressive conversation piece.

The algorithm that the dive computer runs off of is only available on Oceanic computers. It is easily customizable for even the most conservative of divers. There are four modes available, too, for you to choose from.

Oceanic also provides firmware that can be updated which will keep your dive computer up to speed at all times. These updates also mean that you shouldn’t have to replace the computer anytime soon after you invest into the Geo 2.0.

The price point is also appropriate for an entry-level diver as well as advanced divers. By being able to select whether or not you are more advanced, this computer is an excellent choice for any diver.

You can find the Oceanic Geo 2.0 dive computer on Amazon.

You can also find it over at Leisure Pro for anywhere from $280-$350 depending on whether or not you can find it on sale.

There are two color choices that you can choose from, too. The first is black with the sea blue accents on the face. The other is white also with the sea blue accented face. 

The white one with the blue accents is a little more challenging to find, but if you find it, you can expect to pay the same price as the black one.

Real Reviews from Real People

If you go check out Amazon, you’ll find that there are plenty of positive reviews written from happy customers. There are some negative reviews, too, but you’ll need to decide if their reports make a difference in how you view the dive computer.

“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 (sic) 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 24 hours after entering required decompression. My biggest gripe is that you cannot enter your nitrox mix, and then confirm that it was entered correctly.”

“I love my diving computer…It has great algorithms and settings to tweak them for more conservative or less conservative no decompression times according to conditions (such as cold water, strong current or feeling tired that day). The light works well when diving at night and it feels sturdy and resistant to small bumps here and there. I’me a divemaster and I used to use this computer to work, doing 3 dives a day on high season. I trust it because I’ve felt good with it. It does sound the alarm quickly if you raise your arm to hold the anchor line or something like that which is annoying and also is annoying that the alarm doesn’t sound loud enough when actually ascending too fast. If I’m wearing a hood I can barely hear it. Also the size of the computer is not as small as I thought. It looks good on my arm when I have the neoprene suit on but it looks too big if I’m not (I’m 5’7”). It’s somewhat bigger than the Suunto D4.”

Also had positive things to say more recently on June 25, 2018. “Fantastic watch. Lots of great features and works as advertised. A lot of the reviews say that this watch it too complicated, however, if you understand Nitrox, PO2 and O2 saturation, everything makes sense. The menus aren’t that hard to navigate, however, I am a rather tech savvy person.”

There is one review in particular, from Ray, that has a few things to make you question as to whether or not this is the dive computer for you. “After spending almost $500, you need to pay another $100 or so for a USB cable to connect your watch to a PC. This left a really bad taste in my mouth. When I bought my Suunto Vyper (roughly $300) it came with a cable to download log data and such. I never considered to check to see if a device comes ith the necessary connector to use it fully – this is quality stuff, right? At the very least, if you’re going to nickel and dime your consumers, be like apple and charge a reasonable $20-30 for your $0.75 Chinese fabricated USB cable, but $100?”

“I generally don’t care about my no decompression time when doing 1 minute free dives – I guess if I was an idiot and was mixing freediving and scuba the same day I might. Regardless, what I want to know 905 of the time during a dive is 2 things: how deep (most important) am I and how long have I been under water. Things are more cluttered in the display than I’d like when working in a stress environment (as all free dives are) and everything on the display pretty much the same size and boldness – no call outs.” He has a lot more information in his very detailed review that is definitely helpful and worth taking a few minutes to read.


How the Oceanic Geo 2.0 Compares with Other Dive Computers

The dive computer is an excellent mid-entry level option when it comes to dive computers. It’s also easy to read the display and has a countdown timer to indicate when it’s safe to stop.

The design is also entirely intuitive, so it doesn’t take long for you to get to know how it works. It’s also durable, as would be expected for a dive computer that is capable of going as far as 14,000 feet down.

You may not like the bar graphs, though, because they can be a little on the small side. Although the user manual isn’t too great when it comes to explanations, it’s not that big of a deal because the dive computer is easy enough to use without it.

Looking at the face of the computer, you’ll compare it to the likes of the Cressi Leonardo. The Geo 2.0 has a screen that is easier to read numerically along with an indicator light when the alarm goes off.

Other dive computers that compare well to the Oceanic Geo 2.0 include the Mares Nemo Wide Dive Computer wrist watch, the Aqua Lung i100 Dive Computer, and the Suunto Zoop 2.

The Nemo Wide Dive does not compliment the wrist quite as well as the Geo 2.0. It looks like a dive watch and is probably not something you’d want to wear when you’re out of the water. It is, however, a bit less expensive than the Geo at $205 over on Amazon.

If you’re looking at the Aqua Lung i100 Wrist Computer as an option, this looks like a stop watch. It’s not very sleek looking, but it is under $200 and has the same four modes that the Geo 2.0 does. It is easy to use, but you’ll likely only ever wear it when you go diving.

The Suunto Zoop is another option, but only if you want something that is attached somewhere other than your wrist. It is an online dive computer that would be connected to a hose and keeps an eye on your pressure and act as a guide as you dive.

What We Think

If you’ve been diving for a while or you have a higher budget to play with, then the Oceanic Geo 2.0 Dive Computer is an excellent choice. Being able to adjust your dive computer individually is fantastic because it means that if you’re more advanced, you can make your computer your own.

If you’ve had a beginner dive computer in the past, then you’ll know a little about what to expect if you choose the Geo 2.0 is the next one in line for purchasing. It’s an upgrade from basic dive computer and has some great features to consider when you’re deciding on which dive computer you’re going to buy.

You can be the king or queen of the deep with this dive watch if this is the way you want to go. We think it’s an excellent choice because of all of its capabilities and the way you can customize it to meet your needs.

As always, do your research and compare different models to figure out which one is going to be best for you and your diving needs, but we think you can’t go wrong with this one.
