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. Every number is explained, every setting travels with the plan, and your buddy opens it free in the app or in any browser. Everything runs offline. Big type for direct sun, big targets for wet hands, routine tasks in seconds. DECO PLANNER (PRO) The one tool you pay for. - 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 (minute, 30 seconds or exact) 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 limit, the number and the fix: PPO₂, END, gas density, CNS, OTU, hypoxia, reserve - Repetitive dives, with tissue loading carried over the surface interval - Plan variants side by side, graph overlays included - Share by QR code or link, no purchase needed to read it. Export the table or a slate image - Cross-checked against reference planners, stop for stop 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, doubles and sidemount included - 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 - 35+ cylinder specifications from manufacturer data - Tutorials on gas physics, decompression theory and trimix - Tap any result for what it means and why it matters CERTIFICATION WALLET 25+ agencies, 190+ certifications, and a diver profile with insurance and emergency contacts. BUILT FOR THE BOAT - Fully offline, on phones and tablets - Exact decimal math in every gas number - Eight languages: English, German, Turkish, Swedish, Russian, Polish, Simplified Chinese, Korean - Light, dark and automatic themes No ads. No account. Your dive data stays on your device, and the optional usage analytics can be switched off in Settings. Dive Kit helps you plan and check your numbers. It does not replace training, certification or your own judgment. Analyze your gas, dive within your limits, plan conservatively. PRICING The Deco Planner is the only paid tool: a one-time lifetime purchase or a subscription. Everything else is free, for everyone.
