View Full Version : magnetic north vs true north

Should my GPS be set to MN or TN or does it make any difference? I know that is does when using GPS with a compass and topo map, but what about just simply using the Go To feature. Will either one throw you off any??

The GPS will point in the right direction no matter what you set the GPS to display. From there I guess it's personal preference.

For me, I use true north, since that's what most of the maps I use are oriented to.

I have in the past on some caches where it is hard to get a signal under trees set it to magentic. Then I can go out into a clearing and read the bearing and distance from the GPS, then use a real compass to see just what direction that bearing is.
