What I am looking for are some neat little tricks to land navigation to enhance my SAR training classes. Some of the ones I have picked up are: calculating distance to an object just using a compass. Navigating using a compass without a map. modifying a military lensatic compass for night use.<br><br>Any tips will do, for use with compass, gps, map, etc.<br><br>Thanks<br>Ted Fisher<br>Vermilion County Search and Rescue
