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

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.
