compliance with EN 13319)
• Maximum depth of operation: 100 m/328 ft (complying with EN 13319)
• Accuracy: ± 1% of full scale or better from 0 to 80 m/262 ft at 20°C/68°F (complying
with EN 13319)
• Depth display range: 0 to 150 m/492 ft
• Resolution: 0.1 m from 0 to 100 m/1 ft from 0 to 328 ft
Temperature display:
• Resolution: 1°C/1°F
• Display range: -20 to +50°C/-9 to +122°F
• Accuracy: ± 2°C/± 3.6°F within 20 minutes of temperature change
Calendar clock:
• Accuracy: ± 25 s/month (at 20°C/68°F)
• 12/24 h display
Displays only in NITROX mode:
• Oxygen %: 21 - 99
• Oxygen partial pressure display: 0.2 - 3.0 bar, depending on the limit setting
• Oxygen Limit Fraction: 1 - 200% with 1% resolution
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
