Dual Algorithm Technology
Choose the one dive computer that’s liberal, conservative or middle-of-the-road.
Dual Algorithm™ technology lets you choose the decompression algorithm that best suits your diving needs without compromising safety.
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 our Dive Computers and other manufacturer's computer algorithms for many years.
Choose Pelagic Z+ for:
Conservative Recreational Diving
When applied to standard recreational diving, the Pelagic Z+ Algorithm basis increases the conservative factor of the OC1 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 Dual Algorithm 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).
Quality, Function and Style. The GEO 2.0 has an upgraded look with a stainless steel accent ring and new color combination and now includes Dual Algorithm, Deep Stop option and a redesigned user interface with "Step Back" which allows forward and backward navigation through menus and settings. Additionally, a second Nitrox mix (both programmable to 100%) is available, as well as Firmware Auto-Update which allows the user to download and install operational improvements or even future new features through the PC Interface (with optional cable).
