and the leading tissue compartments react to the 30% limit of M-value. At this depth the first
decompression stop takes place.
When the ascent continues, the GF moves from 30% to 70%. GF 70 indicates the amount of
supersaturation allowed when you get to the surface. The lower the GF High value is, the
longer shallow stop is needed in order to o-gas before surfacing. In the following illustration,
GF High is set to 70% and the leading tissue compartments react to the 70% limit of M-value.
At this point you can come back to the surface and finish your dive.
The default setting of Suunto's Bühlmann 16 GF dive algorithm is 30/70. All values other than
the default values are out of recommendation. If you modify the default values, the value
number turns red and a warning appears on the screen.
WARNING: Do not edit gradient factor values until you understand the eects. Some
gradient factor settings can cause a high risk of DCS or other personal injury.
