4.27. Personal setting
Suunto Fused™ RGBM 2 algorithm provides 5 personal setting options (+2, +1, 0, -1, -2). These
options refer to decompression models. +2 and +1 can be considered conservative, while -2
and -1 can be considered aggressive. 0 is the default setting and is neutral, for ideal
conditions. Generally speaking, conservative means safer. In practice it means that a dive at a
given depth is shorter due to the decompression obligation (the no decompression time is
short).
Conservative also means that the time the diver needs to spend on decompression is longer.
For recreational divers, a conservative model means less time in the water in order to avoid
decompression requirements. For technical divers, however, conservative means more time in
the water because of the longer decompression requirements imposed during ascent.
Aggressive models, on the other hand, increase the potential health risks of a dive. For
recreational divers, an aggressive model allows more time at depth, but may significantly
increase the risk of decompression sickness (DCS).
The default setting for the Suunto Fused™ RGBM and Fused™ RGBM 2 is to use a compromise
(0 setting) between conservative and aggressive. With the personal setting, you can select
gradually more conservative or more aggressive calculations.
There are several risk factors that can affect your susceptibility to DCS like your personal
health and behavior. Such risk factors vary between divers, as well as from one day to
another.
The personal risk factors which tend to increase the possibility of DCS include:
exposure to low temperature – water temperature less than 20 °C (68 °F)
•
below average physical fitness level
•
age, particularly over the age of 50
•
fatigue (from over exercising, lack of sleep, exhausting travel)
•
•
dehydration (affects circulation and may slow down off-gassing)
stress
•
tight fitting equipment (may slow down off-gassing)
•
obesity (BMI that is considered obese)
•
patent foramen ovale (PFO)
•
exercise before or after dive
•
strenuous activity during a dive (increases bloodflow and brings additional gas to tissues)
•
WARNING: SET THE CORRECT PERSONAL SETTING! Whenever it is believed that risk
factors that tend to increase the possibility of DCS exist, it is recommended that you use this
option to make the calculations more conservative. Failure to select the correct personal
setting will result in erroneous dive and planning data.
The five-step personal setting can be used to adjust the algorithm conservatism to fit your
DCS susceptibility. You can find the setting under Dive settings » Parameters » Personal.
