[QUOTE="casper, post: 58463, member: 562"] Beware that in flat feature less scrub country (ie no landmarks to triangulate your position off) simply taking a compass bearing when leaving your car is only useful in finding your way back to it if you intend to walk in dead straight line out and back because any deviation from that bearing will affect your easting and/or northing and more so the further out you go from your start point. So returning on your back bearing would (if you were counting your paces) bring you back to a different location to the one that you left from. If you're super lucky you might be able to see your car in the distance - but because nobody counts their paces you'll probably walk straight past your car having missed it by 500 metres....... and you're lost!! However a compass and can GPS compliment each other. Learn how to orientate a map with a compass, and find your position on that map using triangulation, or find your position on that map using GPS coordinates from your favourite device and you'll feel much more confident about venturing into the bush or the outback. casper [/QUOTE]
