The last locked bearing is stored and available the next time the
compass is activated. In DIVE mode, the locked bearings are also
stored in the log. To lock a bearing:
1. With the compass active, hold the watch in front of you and turn
yourself towards your target.
2. Press [SELECT] to lock the current degree displayed on the watch
as your bearing.
3. Press [SELECT] to clear the lock.
If, at any point, your bearing moves outside the compass display,
right or left arrows appear to show turn direction.
Suunto Vyper Novo provides help for navigating square and
