If Your Computer Runs It,
DiveCommand Matches It.
Bühlmann ZHL-16C at GF 40/85 is the factory default on every major dive computer. DiveCommand uses the exact same constants, compartment half-times, and gradient factor implementation — verified using an independent Python reference implementation, not self-comparison.
12,067 test cases spanning every depth, gas mix, and GF combination. Agreement at Δ=0 at every single case. The validation harness is public — open it in any browser and run the tests yourself.
An Expert In
Every Panel.
Every calculation in DepthPlanner runs offline. The AI assistant is different — it’s a real-time expert you can ask questions in plain language. Why is my NDL shorter at altitude? What does 90% nitrogen load mean? Why does my Shearwater show a different number?
Included with DiveCommand Annual or Lifetime. Your dive data stays fully offline; the assistant only needs internet when you ask it a question.
