It calculates best mix, for Open Circuit dive or CCR diluent, Bailout best mix, by setting END or PpN2, and PpO2.
Gas fills are calculated for Partial Pressures fill, continuous flow ( stick ), Banked EAN fill, giving you Filling costs.
For continuous flow ( stick ) trimix fill, the software calculates and shows you the state of the two O2 sensor, to obtain desired trimix.
Top-up function let's you calculates the mix you obtain by filling a thank, with given pressure and mix, with the content of another tank ( other mix ). You can repeat to recuperate gas from multiples tanks residual gases.
What-if function, calculates the obtained mix by filling a tank with given pressure and mix, with certain amount ( bars or Psi ) of O2, He and Air.
The software supports meters, feet, Psi, Bars, °C, °F, cubic inches
