Logbook/dive profile memory:
•
Recording interval: 20 seconds adjustable (1,10,20,30,60s).
• Memory capacity: approximately 42 hours of diving with 20 second recording interval
• Depth accuracy: 0.3 m/1 ft
Operating conditions:
•
Normal altitude range: 0 to 3,000 m/10,000 ft above sea level
• Operating temperature: 0°C to 40°C/32°F to 104°F
• Storage temperature: -20°C to +50°C/ -4°F to +122°F
It is recommended that the instrument be stored in a dry place at room temperature.
NOTE Do not leave the dive computer in direct sunlight!
Tissue calculation model:
•
Suunto Deep Stop RGBM algorithm (developed by Suunto and Bruce R. Wienke, BSc,
MSc, PhD)
• 9 tissue compartments
• Tissue compartment halftimes: 2.5, 5, 10, 20, 40, 80, 120, 240 and 480 minutes (on
gassing). The off gassing halftimes are slowed down
• Reduced gradient (variable) "M" values based on diving habit and dive violations. The
"M" values are tracked up to 100 hours after a dive
• The EAN and oxygen exposure calculations are based on recommendations by R.W.
Hamilton, PhD and currently accepted exposure time limit tables and principles
Battery:
•
One 3 V lithium battery: CR 2450
• Battery storage time (shelf life): Up to three years
• Replacement: Every three years, or more often depending on dive activity
