* NOTE
Data refer to calculations performed with
the following parameters:
• Average length of every dive 45 min
• 12 months of Off-Mode
• Use of the alarm every day.
• Battery life is affected by the operating
temperature.
• At lower temperatures the battery life
decreases.
• The life of the battery will vary
depending on use.

Algorithm
• RGBM Mares-Wienke, the result of a
collaboration between Dr. Bruce R. Wienke
and the Mares Research and Development
Center.
• 10 tissue compartments
• Reduction of permissible gradient
(M factors) in case of repetitive dives, deeper-
than-previous dives or multi-day diving.
• deep decompression stops
• safety stop
• ascent rate: 10 m/min
• altitude programs:
• P0 from 0 to 700 meters ASL (0-2296 ft);
• P1 from 700 to 1500 meters ASL
(2296-4921 ft);
• P2 from 1500 to 2400 meters ASL
(4921-7874 ft);
• P3 from 2400 to 3700 meters ASL
(7874-12139 ft).
