Safety stop time
A safety stop is always recommended for every dive over 10 meters (33 ft). You can adjust the safety stop settings as follows:
3 min: The safety stop is always a 3-minute stop, even after the last decompression stop. The safety stop time is not included in TTS (time to surface).
4 min: The safety stop is always a 4-minute stop, even after the last decompression stop. The safety stop time is not included in TTS (time to surface).
5 min: The safety stop is always a 5-minute stop, even after the last decompression stop. The safety stop time is not included in TTS (time to surface).
Always OFF: No safety stop is shown during the dive.
Adjusted: A 3-minute safety stop is added after decompression, but the duration of the stop is adjusted based on the dive profile. This means that it can be shorter if the time is spent in the shallow. The predicted time is included in TTS (time to surface).

Ascent speed violation during dive does not make the safety stop time longer.
