Suunto Fused™ RGBM 2 algorithm tissue calculation model

  • 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.

Bühlmann 16 GF algorithm tissue calculation model

  • Developed by Swiss physician Albert A. Bühlmann, M.D.
  • Suunto has used Bühlmann ZHL-16C version as a basis of the development
  • 16 tissue compartments
  • Tissue compartment halftimes for nitrogen: 4, 8, 12.5, 18.5, 27, 38.3, 54.3, 77, 109, 146, 187, 239, 305, 390, 498, 635
  • The model assumes perfusion limited gas exchange and multiple parallel tissue compartments and uses an inverse exponential model for on-gassing and off-gassing, both of which are assumed to occur in the dissolved phase (without bubble formation).

Battery

  • Type: 3.7 V rechargeable lithium-ion
  • Charging: USB: 5 Vdc, 0.8 A
  • Battery life: fully charged, min. 20 hours 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:

Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. Do not try to replace the battery by yourself! It should always be replaced by an authorized Suunto Service Center.

NOTE:

Low temperature may activate the battery warning even though the battery has enough capacity for diving in water with higher temperatures (40 °C or less).
