How Do I Prevent My Dive Computer From Going Into Dive Mode After Rapid Descent in Altitude?

Garmin® dive computers are designed to initiate a dive activity when the device notices a significant change in pressure. This can happen when sky diving or when rapidly descending in a plane among other circumstances. When this happens the watch will be stuck in dive mode. To prevent this, we recommend starting an activity on the device, powering off the device, or adjusting your auto dive settings prior to beginning an activity that can cause a rapid change in pressure.

Adjusting Auto Dive Settings

Some dive computers offer the ability to snooze or turn off the auto dive setting on the device. If you know that you are going to be in a situation when the watch might enter a dive, such as swimming without starting a swim activity or flying in a plane, you may want to adjust the auto dive setting to avoid the device erroneously starting a dive.

Select one of the dropdowns below for specific steps to adjust your auto dive settings.
