1. Turn the compass dial/bezel to the heading you want to "aim" 180.0° for Ontario, Canada or 111° for Ontario, California (not 100% sure where you are) it makes a HUGE difference so my numbers before were just to teach you how to use the compass.
2. Then rotate the entire compass FLAT in your palm until the floating colored North Arrow lines up to its marked North Indicator.
3. Your heading arrow at the front/top of the compass is now pointing toward the set heading; in this case, AMC-5.
See attached example shows how the compass would look if your were aiming to 250°w. Practise doing that and you should get the hang of it in less than 5 mins.
