Tissue calculation model

  • Suunto Fused™ RGBM algorithm (developed by Suunto and Bruce R. Wienke, BSc, MSc, PhD)
  • 15 tissue compartments
  • Tissue compartment halftimes for nitrogen: 1, 2, 5, 10, 20, 40, 80, 120, 160, 240, 320, 400, 480, 560 and 720 min. The on-gassing and off-gassing halftimes are the same.
  • Tissue compartment halftimes are divided by a constant factor to obtain helium halftimes.
  • 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 exposure calculations (CNS% and OTU) are based on recommendations by R.W. Hamilton, PhD and currently accepted exposure time limit tables and principles.

Battery

  • Type: rechargeable lithium-ion
  • Battery life: fully charged, min. 20h dive time

The following conditions have an effect on the expected battery lifetime:

  • The conditions in which the unit is operated and stored (for example, temperature/cold conditions). Below 10°C/50°F the expected battery lifetime is about 50- 75% of that at 20°C/68°F.
  • The quality of the battery. Some lithium batteries may exhaust unexpectedly, which cannot be tested in advance.
NOTE:

Low temperature or an internal oxidation of the battery may activate the battery warning even though the battery has enough capacity. In this case, the warning usually disappears when the dive mode is activated again.

Radio receiver

  • Bluetooth® Smart compatible
  • communication frequency: 2.4 GHz
  • range: ~3 m/9.8 ft
