DSAS supports six calculators useful to divers: Diver Safe Distance, Underwater Pressure, Blast and Frag, Cube Root, Unit Converter (with support for converting between different units for water flow) and a standard calculator. The Diver Safe Distance calculator lets a user enter an explosive weight, select an explosive type (such as dynamite, ANFO or C-4) and select a PSI value (such as threshold lung damage or 1% lethality). The calculator will then compute the safe diver distance.
