Diveplanner Tec & Rec
Decompression dive planner and logbook
Diveplanner Tec & Rec is a complete decompression planner for recreational and technical divers. Build multi-level, multi-gas dives in open circuit or closed circuit rebreather (CCR), down to 300 m, and get a clear runtime with every stop, gas switch and warning.
Plans are computed with the Bühlmann ZH-L16C algorithm and your own gradient factors, in salt water, fresh water or at altitude. Contingency plans (deeper, longer, lost deco gas, GF 100, CCR bailout) are generated automatically, so you can brief and dive with confidence.
The Rec version is free, with one gas (air or nitrox up to 40%) to 66 m. Tec Basic and Tec Advanced licences unlock trimix and more gases, and every licence can be tried free for two weeks.
