If we compare Oceanic Geo and Geo 2.0 dive computers we may notice major updates, which Oceanic made to its new dive computer that do not exist in Geo. They include:
As was mentioned above this dive computer has 4 buttons on the user's interface: Mode, Select, Light, and Advance.
I couldn’t say that buttons are very small, but sometimes you may find it difficult to press if you wear 5 mm thick gloves – I needed to bend my wrist a bit down to make it easier.
Oceanic Geo has 1 bar graph and it is shared either to display nitrogen loading or oxygen accumulation:
Before jumping into water you need to set and customize your Oceanic Geo, and first thing you will surely do – setting up parameters for digital watch functions, like:
All customizable parameters 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.
Below is a summary of what you may set for Normal (Air/Nitrox) and Gauge Modes:
Oceanic GEO: Diving With Air & Nitrox
As a dive computer, Oceanic Geo operates in 3 modes:
When you set Wet activation to ON and get into water, wet contacts of Geo get bridged and if it senses depth of 1.5 meters for 5 seconds, it activates the No-Decompression dive mode.
Depending of what dive option you set – air or nitrox, you will be presented with main and alternative displays with all related information on them, considering your no-decompression and decompression conditions, safety stop and any violations that you may do during the dive.

During No-Decompression dive, Geo may give you Safety Stop prompt upon reaching certain conditions. Besides to all values displayed at No-Deco dive, it will show you required depth for Safety Stop and Countdown Timer. If Safety Stop option was set to OFF – Safety Stop automatic prompt will not appear.
Oceanic Geo will activate Decompression mode if you exceed No-Decompression Limits (NDL) – No-Decompression time and depth. During this mode you will need to ascend to certain depth, displayed on the screen, and stay at this depth required time that is shown on display in order to decompress.
Decompression Mode is presented by main, secondary, and two alternative displays to keep you well-informed about current situation. Below is a summary of the information shown up on these displays:
You will easy swap between displays by pressing Advance button.
Also, if you make any violations – Geo will show information related to each kind of violation with appropriate values, Bar Graphs, icons, and graphics.
Oceanic GEO: Diving In GAUGE Mode
If Oceanic Geo set for Gauge Mode – it will work as a depth gauge and timer and do not perform calculations for nitrogen and oxygen accumulation.
When you perform a dive in Gauge mode – Geo stays locked for 24 hours, and you need to wait 24 hours before you may set Geo for Air, Nitrox, or Freedive modes.
Below is a representation from main, alternative, and secondary displays of what you will see during Gauge mode:
You can swap between displays by pressing Advance button.
Oceanic GEO: FREEdiving
In a Freedive mode Geo works as a depth gauge and calculates nitrogen based on the default FO2 of Air and the amount that you may have after previous dives from the last 24 hours.
Again, you will have an access to few displays with all information related to freediving. Below is the summary from main and secondary displays:
Freediving has its specific displays and set of alarms, like:
After the Transition Period you will have access to following modes:
