Oceanic Geo 2.0 Computer Watch
The Oceanic Geo 2.0 is the first dive computer we'll explore in this guide.
It has a neat interface that offers a ton of features for beginner and intermediate recreational divers.
You'll also love the built-in dual-algorithm that is quintessential to all Oceanic devices.
Overview of Features
Some of the most outstanding features of the Geo 2.0 include:

With the NORM setting, you can opt for air and nitrox, while GAUGE features an additional run timer.
FREE is a popular option, which helps track important calculations and allows divers to switch to NORM seamlessly.
- User-Friendly
As mentioned, one of the central objectives of these dive computers is to ensure they are user-friendly.
Beginners and advanced divers will love the interface design, which allows you to navigate through menus quickly.
Unlike other dive computers, you can cycle forward or backward through all of the settings.
- Two Nitrox Settings
In addition to the user-friendly menu cycling, divers can also choose between two Nitrox mixes.
You can customize the values up to 100% O2 with zero restrictions.
- Minute and Second Displays
There's nothing more important than having the most accurate data at your fingertips.
The display on this dive computer offers both minutes and seconds and a countdown timer for deep stops.
You'll be able to turn the stops on or off while setting two-minute countdowns when you reach half of your maximum depth.
- Easy-To-Read Display
Have you ever used a dive computer that required you to go through different menus before seeing essential data?
Fortunately, the easy-to-read display in this unit shows all relevant information without scrolling.
Divers will have immediate access to depth, temperature, and time with a single glance.
With that said, since this is a beginner-friendly model, the Geo 2.0 doesn't have higher-end metrics.
For example, you won't have access to air integration or a compass.
There is a low-battery indicator that lets you know when to replace your battery before diving as an added benefit.
- User-Changeable Battery
It's often that divers prefer batteries that they can change themselves with their equipment.
If you use a faulty battery in your device, it's easy to remove and replace with a newer version.
Rechargeable built-in batteries, on the other hand, require service centers for any repairs.
With the Geo 2.0, you have full control over replacing your battery whenever you desire to ensure it's always packed.
- Audible and Visual Alarms
You can guarantee you will always be apprised of any changes in your dive data while underwater.
With the combination of audible and visual alarms, divers will be alerted quickly to hazards and changing conditions.
Many find the combination of these two alerts to be preferable to one or the other.
There are several types of alarms that you can customize and set before diving, including:
- PO2 limit violations
- Ascents that are too fast
- Exceeded dive times
- Decompression violations
- Deep stop violations
- Gas switches resulting in PO2 > 1.6
- Basic Dive Log
Compared to some of the more expensive models, the dive log in the Geo 2.0 is somewhat lacking.
You can save up to 24 dives worth of data with samples at two to 60-second intervals.
Once finished, you can then transfer the dive data to a computer using a connector that you purchase separately.
- Dual Gas Mixes
With this unit, you can use two gas mixes that fall between 21% and 100% oxygen levels.
You can also set specific PO2 limits, ranging between 1.2 and 1.6 bar.
- Auto-Updating Firmware
Making sure you always have the latest technology in your dive computer is essential to meet modern demands.
With the Geo 2.0, you'll have automatic firmware updates when connecting the device to a PC.
This feature helps ensure you're always equipped with full functionality while adventuring underwater.
- Build Quality
This dive computer doesn't have a ton of unique materials used in its design, which speaks to its beginner-friendly nature.
The majority of the case is constructed from rubber, which is comfortable to wear and resistant to salt and freshwater.
There is also a stainless steel accent ring that leads to the stainless steel buttons for menu navigation.
Compared to other dive computers, this model is somewhat sleek and stylish.
It indeed has one of the more low-profile designs that you'll find in wrist dive computers.
It also weighs in at approximately 0.55 pounds, which will add very little weight to the rest of your diving gear.

Oceanic Pro Plus 3.0 Dive Computer
The Oceanic Pro Plus 3.0 Dive Computer is a significant upgrade from the basic Geo 2.0.
This model isn't a wrist computer but is a console computer for a more traditional appeal.
There are many modernized features built into the unit that helps bring a more seamless experience.
Overview of Features
This Oceanic computer watch has a lot to offer, including:
- Quick Disconnect
Connecting and disconnecting your dive computer is substantially more comfortable with this model than others.
It features an optional quick disconnect that allows you to twist the locking ring to remove and lock the computer.
When the ring is twisted, you'll have extra security to ensure the dive computer doesn't inadvertently disconnect.
- Large Display
One of the more notable visual features of this dive computer is that it boasts an extra-large display.
The wide viewing screen is essential for seeing all of your relevant data straight away without any confusion.
The screen has an extensive font that is easy for anyone to read while underwater.
Compared to other dive computers, the numbers are up to 22% larger, making it very clear.
