The deco planner built for technical divers, plus eleven free tools for everyone on the boat. Dive Kit is a scuba deco planner for open-circuit, trimix and CCR dives on Bühlmann ZH-L16C with your gradient factors. It shows what every what-if costs: deeper, longer, a lost gas, a bailout from any point in the dive. Big type for direct sun, big targets for wet hands, routine tasks in seconds. Deco Planner (Pro) - Multi-level profiles with the deco woven around your levels: stops between levels when the plan needs them, gas switches placed where the PPO₂ allows - Gradient factors, last stop, ascent rates, air breaks, stop rounding (1 min, 30 s or 1 s) and PPO₂ bands per gas, all set per plan - Contingency tabs: deeper, longer, lost gas, or build your own. Each shows the extra run time, TTS and CNS against the base plan - Modifiers: working and deco SRMV and a delay at depth, on the base plan or on one contingency - CCR: setpoint schedules by depth, diluent switches, dilout, and open-circuit bailout from the end of the profile, after any level, at a run time or on ascent - Gas per cylinder: remaining pressure at each stop, a reserve per cylinder, ascent pressure, and what happens when a cylinder runs dry - Live warnings with the number and the limit: PPO₂, END, gas density, CNS, OTU, hypoxia, reserve - Repetitive dives, with tissue loading carried over the surface interval - Plan variants, overlaid on one graph - Share by QR code or link, no purchase needed to read it. Export the table or a slate image Eleven Free Tools No ads, nothing behind a sign-up. - Best Mix: nitrox and trimix by MOD, helium picked by END, with narcotic and density limits - Gas Specs: EAD, PPO₂, END and gas density with color-coded warnings - Gas Usage: multi-level consumption, turn pressure, thirds to sixths - SAC/SRMV: your real breathing rate from a dive; for twinsets and sidemount, enter the combined cylinder volume - Buoyancy: weighting from suit, body, gear and water, with lift and overweighting advisories - Blender: partial-pressure and continuous blending with real-gas corrections and expected analyzer readings - Mix Result: what a top-up or a decant actually gives you - Checklists: your own pre-dive routines and rebreather presets, with timers that survive closing the app - Cylinders, Converter, Signals. Cylinders named the way you buy them: AL80 at 3000 psi, or litres Reference & Learning - 90+ illustrated, searchable dive signals and 35+ cylinder specifications - Tutorials on gas physics, decompression theory and trimix, and help on key results Certification Wallet 25+ agencies, 190+ certifications, and a diver profile that holds your dive insurance details. Built for the Boat - Fully offline, on phones and tablets - Eight languages: English, German, Turkish, Swedish, Russian, Polish, Simplified Chinese, Korean - Light, dark and automatic themes No account. Your dive data stays on your device. Usage analytics and crash reports are optional and can be switched off in Settings. Pricing The Deco Planner is the only paid tool: a one-time lifetime purchase or a subscription. Everything else is free, for everyone. Warning and Disclaimer Dive Kit is a reference and planning aid for trained divers, and that covers all its tools. It is not a dive computer and not a substitute for training. The deco planner is for divers trained in decompression diving, and gas blending is for trained blenders. Results can be wrong, so check every result against a second source. Dive Kit is provided as is, and you use it at your own risk.
