Oceanic Geo 2 is a further development of well-known dive computer Geo. After 3 years from launching Geo, Oceanic came up with the upgrade to this dive computer. New dive equipment was named Geo 2 and came out with refined design, Dual Algorithm, Dual gas mix, Switch gas options and several other improvements, which made this scuba dive computer really unique among dive computers of the similar class.
If we classify all dive computers as an entry, advanced, and high-tech dive equipment, we my place Oceanic Geo 2 very close to high-tech line and it doesn’t need to be hoseless air-integrated in order to be perfect – because it already is!
This computer may be successfully used and satisfy needs of the beginners, can be recommended dive computer for technical divers, and freedivers too. Even though it has manuals that is hard from the beginning to figure out all buttons combos and what to expect, but after couple of times running through it and playing with Geo 2 at the same time – there will not be any difficulty whatsoever!

After comparing Geo 2 and Geo dive computers, we may see major updates, which Oceanic made to its new dive computer that do not exist in Geo. They include:
As was mentioned above Oceanic Geo 2 has 4 buttons on the Interactive Control panel: Mode, Select, Light, and Advance.
Geo 2 has two bar graphs to display nitrogen loading and ascent rate:
Oceanic Geo 2 has Dual Algorithm feature – it means that you may choose between more liberal and conservative diving. And you may add even higher conservative factor by setting Tissue Loading Bar Graph (TLBG) alarm and Personal Conservative Factor. Algorithms are listed below:
Before diving you need to set desirable parameters before going underwater, of course. As this dive computer made with digital watch functions, so the first parameters you will probably want to set – is your digital watch parameters. It is really easy, just follow the instructions - when and for how long press certain button! Digital watch parameters listed below:
All parameters in Oceanic Geo 2 are divided into certain Groups where you may set FO2, variety of alarms for Normal and Gauge Modes (for freediving you will set alarms separately and they are accessible from Freedive Mode menu), and number of utilities. Here you will really need to practice with the manuals to get familiar with buttons combinations, because it may be confusing since the beginning!
Below is a summary of what you may set for Normal (Air/Nitrox) and Gauge Modes:
To assist us during diving, Geo 2 dive computer has main and alternative displays with all information related to type of dive, No-Decompression or Decompression conditions, Deep and Safety Stops, and any violations you may have. Also you may switch between gas mixes during the single dive.
Oceanic GEO 2: Diving With Air & Nitrox

You need to press Advance button with certain duration of time to access alternative displays, Deep Stop and Safety Stop displays. To switch gases you need to use Mode button and for Backlight – Light button.
If you need to switch between gases – it is easy to do – just use combination of Mode and Select buttons. Just remember, that dive begins with Gas 1 and switching is blocked when you are on surface, except during first 10 minutes of the Transition Period when you resurface after the dive.
Decompression mode starts when you exceed theoretical No-Decompression limits of time and depth. If this happens – Oceanic Geo 2 activates an alarm, all 5 segments on TLBG are filled up and flashing and UP Arrow icon will flash too.

At that time you need to ascend to required Stop Depth that is shown on the display or slightly deeper and stay for decompression for certain Stop Time, which is displayed too.
Also, if you make any violations (ascending shallower than required and stay there for some time) – Oceanic Geo 2 will show information related to each kind of violation with appropriate values, Bar Graphs, icons, and graphics. And, of course, you will not be given any off-gas credits if you ascent shallower, and moreover you will be given penalty minutes and it is your obligation to fulfill you decompression correctly to stay out of Decompression Sickness (DCS).
Oceanic GEO 2: Diving In GAUGE Mode
If Oceanic Geo 2 set for Gauge Mode – it will work as a depth gauge and timer and do not perform calculations for nitrogen and oxygen accumulation, and it will be locked to this mode for 24 hours if dive in Gauge mode was completed.
Below is a representation of information from main and alternative displays, related to Gauge Mode:
Oceanic GEO 2: FREEdiving
As Oceanic Geo 2 may be used for freediving activities, you need to set some specific parameters for this sort of diving:
In a Freedive mode Oceanic Geo 2 dive computer works as a depth gauge and nitrogen calculation is based on the default FO2 of Air and the amount that you may have after previous dives from the last 24 hours.
Below is a representation of information from main and alternative displays, which you will certainly have during freedive:
Freediving has its specific displays and set of alarms, like:
After the Transition Period you will have access to following modes:
Oceanic GEO 2: What Divers Say
As you may see, Oceanic Geo 2 may be recommended dive computer for the beginners, technical and free divers. It offers great range of features, like Dual Algorithm, Dual Gas; Gas switching, improved and user friendly interface – these features may easily satisfy the most demanding divers, and it’s all in one small package of the size of wrist watch – and that is the main benefit for us!
And it looks just "cool" on you wrist, as you may wear it as a watch – I got few nice compliments of people from the office about it!
Even though you may find difficult following manuals; pressing buttons while diving in cold water and wearing thick gloves; or difficulties of seeing digits at the sharp angles – these cases do not depreciate great features and benefits that this dive computer may give you during all term of its exploitation.
Another main thing about this dive equipment – it is the price!
If you want to have reliable, friendly and flexible dive computer that will cover wide range of your diving activities and allow you to grow as a diver without needing to buy additional dive instruments and pay for the pack so low price at the same time - Oceanic Geo 2 is for you!
