HLPlanner is completely FREE mixed gas decompression software utilising the VPM-B algorithm. HLPlanner’s “engine” is loosely based on Erik Baker’s Fortran 77 code, available in the public domain. The program has been entirely rewritten in C# and optimised, the core of the algorithm however remains identical and therefore produces (or at least that’s what we observed so far) closely matching results.
Main program features:

• Easy to use and highly functional user interface
• Support for full range of gases and profiles
• Full support for both imperial and metric units
• Automatic selection of gas mixes based on depth
• Calculation of gas mix usage in bar/psi and ltr/cuft depending on cylinder size
• Customizable level of safety
• Professional quality printouts
• Easy range planning with O2 bailouts for “loss of deco gas” scenarios
• Full support for repetitive diving with no limit on the number of dives per mission
• and more...
