3.7.4 Setting bearing lock

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.
The default bearing is North.
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 a reef
before leaving the boat.
