AERIS Dive Computer Algorithm
Decompression theory can be trusted only as far as it has been demonstrated by actual test dive data. In 1987 a unique series of experiments were conducted by Diving Science and Technology (DSAT). Commissioned by the Professional Association of Diving Instructors (PADI), these Doppler ultrasound monitored human experiments conducted by Dr. Michael Powell produced the most comprehensive data set that exists for recreational divers to this day. These data were used to validate the PADI Recreational Dive Planner and are the basis of the algorithm used in all AERIS Dive Computers.
Diving By The Colors
AERIS Dive Computers are designed with color-coded bar graphs; green, yellow and red. These graphs monitor three very important diving parameters; nitrogen accumulation, oxygen loading and your personal ascent rate. Pixels build up in each of these color-coded areas to give you a quick, easy reference of these perameters. Proper monitoring of these graphs allows you to select the personal degree of conservatism you wish to build into each dive, putting you in control of your margin of safety.
*Battery Life: Battery life estimates are based on full-capacity batteries, and continuous usage as described.
- 7 days per week
- 2 dives per day
- 1 hour dive time
- 2 hour surface interval
- 18 hour interval from last dive to the first of the next day
**AERIS 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, and other variables also effect the number of dives that can be stored. Although as many as 150 dives might be stored for consistent 60 foot dives with the Sampling Rate set for a 10 foot rate, as few as 3 may be stored when the profiles fluctuate and the sampling rate is set for a 2 second rate.
