Going Diving

The dive computer turns on automatically when it detects water (Disabling the Auto-boot When Wet Setting). If you start a dive without turning on your dive computer, the dive computer uses the most recent surface pressure to determine depth. For the most accurate depth information, always power on your dive computer manually and wait at least 10 minutes before beginning a dive, especially after traveling.

If you store the dive computer while it is still wet, it may inadvertently turn on and drain the battery.

If necessary, select Dive Mode, and select a dive mode.
Select Start Dive With.
Review the dive setup options, and if necessary, select View All Setup to edit the dive settings (Dive Setup).
Wait with your arm out of the water until the dive computer acquires GPS signals and GPS turns green (optional).

The dive computer requires GPS signals to save your dive entry location.
Select Confirm.
Descend to start your dive.

The activity timer starts automatically when you reach a depth of 1.2 m (4 ft.).

NOTE: If you start a dive without selecting a dive mode, the dive computer uses the most recently selected dive mode and settings.
Select an option:
- Press NEXT to scroll through the data screens and dive compass.
  
  TIP: You can also double tap the device to scroll through the data screens.
- Press ENTER to view the in-dive menu.
When you are ready to end the dive, ascend to the surface.
Keep your arm out of the water so the dive computer can acquire GPS signals and save your dive exit location (optional).
Wait for the DIVE END timer to count down.

NOTE: When you ascend to 1 m (3.3 ft.), the DIVE END timer begins counting down (Dive Setup). You can press ENTER, and select Stop Dive to stop the dive before the timer elapses.

The dive computer saves the dive activity.

TIP: You can view your diving history in the dive log app (Viewing the Dive Log App).

Dry off the dive computer.
