DecoPlan

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…
