Safety stops

A three (3) minute Safety stop is always recommended for every dive over 10 meters (33 ft). When a safety stop is required, the minimum ceiling value (3 m) appears in the switch window.

The time for a safety stop is calculated when you are between 2.4 and 6 m (7.9 and 20 ft).

This is presented with up and down arrows on the left side of the stop depth value. Safety stop time is shown in minutes and seconds. The preferred safety stop time can be set in the Algorithm menu under Safety stop.

saftey stop2

Ascending shallower than 2.4 m will trigger an alarm in the window indicator. Please descend below the 3m ceiling value.

saftey stop3

If the depth goes below 6 m (20 ft), the safety stop timer will stop and resume counting once you are again inside the safety stop window. Once the timer shows zero, the stop is done and you can ascend to the surface.

NOTE:

If you ignore the safety stop, there will be no penalty. However, Suunto always recommends that you perform a safety stop for every dive to minimize the risk of DCI.

NOTE:

If you set the safety stop setting to off, there will be no safety stop indications when you arrive to the safety stop window.
