The Oceanic Geo 2.0 dive computer is perfect on its own or as a backup to any dive computer. With Dual Algorithm and optional conservative factory settings, the Geo 2.0 may be programmed to provide no-deco and deco profiles similar to virtually every computer on the market.
The 5 year warranty is unique to Australia.
Powered by Oceanic's exclusive Dual Algorithm™ - your choice between Pelagic DSAT (Spencer/powell data basis) or Pelagic Z+ (Buhlmann ZHL-16C data basis)
4 Operating Modes: WATCH (Alternate Time, Chrono, Daily Alarm, Countdown Timer), NORM (Air and Nitrox), GAUGE (with run timer) and FREE (tracks calculations to allow switching between NORM and Free)
User-friendly Interface with "Step Back" - allows forward and backward navigation through menus and settings
Switch between up to 2 Nitrox mixes to 100% O2 with no restriction (Gas 1 may be up to 100%, and may be less or greater than Gas 2)
Stop times <3 minutes - displays minutes & seconds
Deep Stop with Countdown Timer - maybe turned on or off. 2 minute countdown at half your max depth, for dives greater than 80 ft / 25m
Single button access to "Last dive" display (max depth & bottom time)
Data Retention - maintains calculations indefinitely when the battery is changed
Audible Alarm with flashing LED light
24 dive on-unit log book
History Mode includes total number of dives, max depth, total dive hours, and lowest temp
Optional PC Interface with OceanLog Download and Settings Upload
Firmware Auto-Update: download and install the latest firmware - these may be operational improvements or even new features
30-DAY SATISFACTION GUARANTEE: We guarantee that at any time during the first 30 days of purchase, your Oceanic product fails to meet your expectations, that product may be exchanged by a participating authorized Oceanic Pro dealer. No questions asked.
Choose Pelagic DSAT for:
Liberal Recreational Diving
The Pelagic DSAT Algorithm safely maximizes dive time for repetitive, multi-level recreational diving. This algorithm relies on the human Doppler studies used to develop PADI’s Recreational Dive Planner (RDP), and has been the basis of Oceanic's and other manufacturer's computer algorithms for many years.
To add additional conservatism, you can also adjust the:
Choose Pelagic Z+ for:
Conservative Recreational Diving
When applied to standard recreational diving, the Pelagic Z+ Algorithm basis increases the conservative factor of the GEO 2.0 by 15-20%.
Liberal Repetitive Deep and Decompression Diving
The Pelagic Z+ uses the Buhlmann ZHL-16C database, which was conducted to meet the more rigorous demands of repetitive, cold-water decompression diving at altitude. The Pelagic Z+ mode maximizes dive times at depth without penalties.
Dive in sync with any buddy, anywhere
Because the GEO allows you to adjust the algorithm basis and its conservatism, you can adjust to closely match just about any other dive computer on the market, allowing you and any buddy to always dive in sync. Diving the same profile increases safety for both divers, and eliminates the need for one person to conduct a much longer or deeper stop when buddying with someone wearing a more liberal dive computer. On repetitive dives, there is no more waiting for the more conservative dive computer to clear. Both buddies will be ready to enter the water at the same time and can continue to dive the same profiles. You can’t control which dive computer your buddy wears, but you can control your ability to dive the same profile.
A note about deep stops:
Both algorithms allow (user ON/OFF option) credit for deep stops for No-Decompression dives in keeping with the data of Morroni et al (2004) and Bennett et al (2007). No penalty is given if the diver skips the deep stop, but it is strongly recommended that a shallow safety stop be made with or without the deep stop in keeping with the experiments of Pilmanis (1975).
It is important to note that neither algorithm provides deep stops for decompression dives since there is ample experimental data [Blatteau et al (2005), Gerth et al (2007), and Gutvik et al (2007)] that indicate that this practice often produces an increase in the risk of DCS.

** Oceanic Personal Dive Computers have user selectable Sampling Rates that determine when data is sampled and stored for subsequent download to associated PC interface programs. More frequent sampling provides more data per dive yet results in storage of fewer dives for download. Use with Air or Nitrox, with or without air integration, dive profiles, Free Diving activities, and other variables may also affect the number of dives that can be stored.
