DecoPlan is a universal dive planner for open-circuit and rebreather (CCR) divers, built around two published decompression models: VPM-B with the critical-volume algorithm and Bühlmann ZHL-16C with gradient factors. NO-DECO PLANNER • No-decompression limits for air and nitrox, safety stop, gas needed • Repetitive dives with surface intervals, altitude and fresh water • NDL table for every mix at a glance TECHNICAL PLANNER • Multi-level profiles, any number of gases (nitrox, trimix, oxygen) • Automatic deco-gas switches by ppO₂, last stop at 3 or 6 m, air breaks on O₂ • Runtime table with ppO₂, END, ceiling; depth profile with the ceiling band • Tissue loading graph, CNS/OTU, gas consumption per cylinder, minimum gas, turn pressure • Model comparison: the same dive through six model settings side by side • Contingency grid: what happens 3/6/9 m deeper or 5/10/15 min longer • Lost-gas scenarios, wet-notes text export REBREATHER (CCR) · PRO • Setpoints for bottom and deco, setpoint switching by depth • Diluent plus up to ten bailout cylinders with their own mixes • Open-circuit bailout: a failure at the turn point (half the bottom time) with the swim back, or at the end of the bottom time • Bailout advisor: how many cylinders, which mixes, switch depths and sizes for the planned depth TOOLS • MOD, END, EAD, gas density, best mix, partial-pressure blending, SAC calculator Six languages: English, Russian, German, Spanish, Simplified and Traditional Chinese. Free, with no time limit: the no-deco planner, open-circuit technical planning on ZHL-16C with gradient factors (one level, any bottom gas including trimix, up to two deco gases), every safety warning, minimum gas and the gas tools.
