Compass, Map, protractor, parachute cord, ahh the memories of navigation in desert's,jungle's, wood's, calling for fire. Yes Land Navigation is a great skill and one that once mastered like shooting a bow will stay with you forever. I served as an 03 in the Marine Corps for 9 years. And tried some of the first GPS's, and to double check used my Lensetic compass. In Desert Storm had one and after batteries did slid it in my cargo pocket and used the compass and map (only thing I trust). some basic rules, one a good compass is never wrong, plenty of young LT's and attest to this. Two, Orientate your map and use declination diagram, then get a resection. Three a ten digit grid will get you anywhere. Four, one often overlooked, know your pace count and keep tract (parachute cord for knots every 100 meters/yards).
