NOTE: If GF Low % value is too low, some tissues may still on-gas when the first stop
occurs.
GF High % eect on the dive profile is illustrated in the following picture. It shows how GF
High % determines the decompression time spent in the shallow phase of the dive. The
higher the GF High % value is, the shorter the total dive time is, and the less time the diver
spends in shallow water. If GF High % is set to a lower value, the diver spends more time in
shallow water and the total dive time gets longer.
The default conservatism setting in Suunto Ocean is 40/85. You can adjust the settings to
more aggressive or conservative than the default value. For recreational divers, more
conservative values mean a lower NDL value to avoid decompression requirements. In
technical diving, conservative values mean longer decompression requirements. More
aggressive settings significantly increase the risk of decompression sickness (DCS).
There are several risk factors that can
aect your susceptibility to DCS, such as 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 the following:
•
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
(aects circulation and may slows down o-gassing)
