Performing a Safety Stop

You should perform a safety stop during every dive to help reduce the risk of decompression sickness.

  1. After a dive of at least 11 m (35 ft.), ascend to 5 m (15 ft.).

Safety stop information appears on the data screens.

The safety stop timer.
When you are within 1 m (5 ft.) of the ceiling depth, the timer starts counting down.
  1. Stay within 2 m (8 ft.) of the safety stop ceiling depth until the safety stop timer reaches zero.

NOTE: If you ascend more than 3 m (8 ft.) above the safety stop ceiling depth, the safety stop timer pauses, and the device alerts you to descend below the ceiling depth. If you descend below 11 m (35 ft.), the safety stop timer resets.

  1. Continue ascending to the surface.
