ZHL-16C + gradient factors and VPM-B. Trimix, multi-gas, runtime & stops.
MOD, EAD/END, best mix, gas density & ppO₂ — nitrox to trimix.
Partial-pressure & real-gas (Van der Waals) blends, top-off, cost.
Diluent limits, loop END & density, OC bailout, scrubber estimate.
Full logbook with SAC/RMV trends, gas cost & equipment hours.
CNS & OTU, ICD on gas switches, fly-after-diving, altitude.
New to the theory behind the numbers? Start with the guides — gradient factors, VPM-B vs Bühlmann and more — or read how we validate the engines against reference software.
DecoLog grows with you — the same tools that plan a 12 m nitrox dive scale to closed-circuit trimix.
MOD, EAD, best mix, NDL tables (PADI/SSI/NAUI/Bühlmann) and your logbook.
ZHL-16C gradient factors, VPM-B, multi-gas runtime, END & gas density.
Setpoint loop gas, diluent limits, OC bailout schedules, scrubber time. See the CCR dive planning guide.
