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).
Wireless Air Integration
Our Sophisticated Personal Dive Computers feature Wireless Air Integration technology.
A transmitter threaded into the first stage high-pressure port continuously sends cylinder pressure data to the dive computer. Frequencies are individually coded to allow multiple divers to swim side by side without interference with other units. Because the transmitter and display module are independent and separately powered units, the dive computer may also be easily used as a stand alone, non-air integrated dive computer.
Patented Air Time Remaining Algorithm
You're at 80 feet with 1300 psi remaining in your cylinder - how long before you need to begin an ascent to a shallower depth?
Our patented Air Time Remaining feature calculates your current depth, breathing rate, cylinder pressure, ascent time, and decompression status to tell you exactly how much time you can remain underwater.
Download and Settings Upload Interface
The PC Interface is an exquisitely detailed digital dive log. It allows you to easily transfer dive data from your Dive Computer to your PC via a plug-in USB cable.
Following download, your dive data is automatically formatted for easy viewing, sorting, analysis, and printing. Enter location, dive buddy and your notes and you've instantly created your own digital logbook. In addition to detailed dive analysis, the dive computer PC Interface also allows you to quickly and easily set most of your user settings and options through your PC.
Automatic Altitude Compensation
Selected Personal Dive Computers automatically compensate for altitude dives up to 14,000 feet, giving adjusted no-decompression times and depths.
Our Dive Computers even automatically recalibrates the depth displays for freshwater instead of seawater above 2,000 feet.
