Compass Declination for GA - WhiteBlaze
2009年8月29日 · If the map is oriented to magnetic north, declination is automatically accounted for when measuring bearings, etc., with the compass. If declination is not listed, measuring the angle formed by the MN and GN pointers will provide that information. Declination is "West" if MN points to the west of GN. And vice versa with regard to East.

2015年9月19日 · If I get to the point where I have to do some declination correction with a topo map, I'm probably tired &/or confused. To avoid error, I write on my topo maps what the declination adjustment formula is: East declination correction; Map Bearing = Magnetic bearing + Declination; Magnetic bearing = Map bearing - Declination.

2016年3月17日 · Just a small tag type compass and some idea of the local magnetic declination. In Maine, for instance, Magnetic North is about 20° West of True North. For people who are really into precise navigation with compass and map, magnetic declination drifts over time and the declination printed on old maps can be off by a few degrees. Current ...

2015年2月20日 · You are wrong on one thing: adjusting the compass' declination for running an orienteering course. Orienteering (the sport) maps typically have multiple lines pointing to (current) magnetic north. So, you wouldn't need them for that either. That's why orienteering compasses, like the Suunto arrow 6, don't have any declination adjustment.

2013年3月22日 · Since the magnetic declination is always changing, the older value printed on maps can be wrong by several degrees. I also updated my links page to show (1) reviews of Gmap4 and (2) sites that are already using Gmap4 to produce online interactive maps.

2015年9月24日 · So, you adjust your compass bezel (the declination) so that when the needle is pointing 13* east of true north, the compass itself is pointing at true north. So, ignore everything else. If declination is 13* east, you adjust your compass declination setting so the red pointy arrow thing (that you line your needle up with) is 13* east of true north.

2016年10月7日 · Seems to me, and I've seen demonstrated, that Maine is way harder than Georgia for someone without 2000 miles of practice and the Whites under their legs. The trail evolves constantly. Magnetic declination has nothing to do with terrain difficulty. Hike every incline/decline both ways then make your decision.

2008年5月25日 · Skids magnetic windscreen got me to thinking. Wonder if a pair of craft magnets could be used at both sides of the bottom of a bugnet door to secure it to a tent? I'm thinking that if a magnet was on the outside of the bugnet and the inside of the tent, it would hold the net close enough to deter bugs.
