Dive Ascent Rate Safety Stop Calculator

Calculate required ascent time and safety stop schedule based on depth, bottom time, and breathing gas. Identify whether a safety stop or mandatory decompression stop is needed

Each component has a specific meaning:

• Depth — The depth recorded for the scenario being assessed.
• Bottom time — The bottom time recorded for the scenario being assessed.
• Breathing gas — The breathing gas recorded for the scenario being assessed.

Note: Interpret the dive ascent rate result against the thresholds and context described above.

Enter the depth, bottom time, breathing gas for the scenario you are assessing. Calculate required ascent time and safety stop schedule based on depth, bottom time, and breathing gas. Identify whether a safety stop or mandatory decompression stop is needed. Use the dive ascent rate result to inform your calculation.
