Our dive computers are designed to automatically turn off 2 hours after activated if they are not dove. No manual shut down feature is available or needed.
Once the dive computer is taken to a depth of 5’ to 8’ and enters dive mode, it will remain on for 24 hours from the time the last dive was completed. After 2 hours the computer will enter sleep mode to reduce the power requirements. However, it will still monitor the oxygen and nitrogen loading, as well as display the saturation time and time to fly for 24 hours.
