A dive plan that flags its own gas problem
An interactive open-circuit decompression planner using the Bühlmann ZH-L16C model, with controls for dive profiles, gases, cylinders, and ascent settings.
- For
- Technical divers reviewing decompression scenarios
- Worth noticing
- Its sample scenario flags a 12-liter air cylinder as insufficient: 449 bar required versus 232 bar available.
Field notes
The planner exposes editable dive depth and bottom time, gradient factors, descent and ascent rates, gas mixes, cylinder size and pressure, and diver gas-consumption assumptions. Its displayed example uses a 40 m, 20-minute air dive and calculates a 53-minute runtime; it then flags the listed 12 L cylinder as insufficient and the 6.43 g/L gas density as above its 6.20 limit. The page labels the tool educational and warns against using it in place of training, a dive computer, or team-validated planning.
