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
