I recently purchased a compass, and I want to learn how to use it to its full potential. The main reason for this is, 1) I need to get my buddy from point A to point B to point C, then back to point A without getting lost next weekend, and 2) we're going to be doing some night dives next weekend where this will come very handy. I know how to do the straight forward and back compass use, but my question is how to go from one straight point to another, make a turn, and go to another point, make another turn, and eventually backtrack my way. I know there is a way to adjust the compass on each turn, but unfortunately I don't know how. I tried googling it, but nothing came up with great detail. The compass I use is Suunto SK7 which has a spot to read your position on the side. If anyone has any suggestions or links to anywhere that will explain the techniques in detail, I would really apprecaite it. Thank you all for your help in advance.
