>>1013922Other compasses often have a view port on the compass housing. You look along that like pic related and can see the bearing, works fine.
Flipping 180 (3200mil) you would only do if you want the back bearing from the feature to yourself, rather from yourself to the feature. Useful when finding your position. You get the back bearing from 3 features you can identify on both the map and the ground, convert the mag back bearings to grid back bearings by adding the current MV of the map you are using, then draw these lines from the features on the map. They'll meet in a small triangle which is roughly your position.
