A bearing is the angle between north and your target. In simple terms, it is the direction you want to travel. Your heading, on the other hand, is your actual direction of travel.
You can set a bearing lock to help you orientate yourself underwater and ensure you maintain your direction of travel. For example, you can set a bearing lock for the direction to the reef before leaving the boat.
You can reset the bearing lock at any time, but you can only clear a bearing lock while at the surface.
To set a bearing lock:
Once you have a bearing locked, the lock position is indicated on the compass rose, as shown below.
Below your heading (large number in center of compass), you also see the relative difference between your bearing and your heading. So, for instance, when you want to travel in the exact direction of your bearing, the lower number should be 0°.
If you want to set a new bearing lock, just repeat the same procedure above. Each bearing lock is recorded in your dive log with a time stamp.
To clear the bearing lock from your compass view, you need to return to the surface.
