and after changing a tank, make sure that each gas mixture is set to the correct value for the corresponding tank.
Predictive decompression prognosis
The calculation of decompression data is based on the assumption that the SP1 / SP2 change(s) will
be performed at the previously selected switch depth(s) (setpoint 1/2). If a diver ignores a required
change or changes the SP1 / SP2 belatedly, Subgear XP-3G will readjust the decompression calculation
accordingly. In case of an ignored switch the dive computer will then base its calculations on the
assumption that the diver will ascend to the surface with the currently selected SP1 / SP2.
