I have myself a Garmin xTrex GPS. So far so good. No complaints.
But I have been wondering - If I am going on a trip and start marking waypoints, should I set my GPS compass to point to True North? Or should I leave it to the default setting of Magnetic North (with 0 declination/variation)?
I am not into mapping but I do mark out trails for jungle hikes for my colleagues and friends to follow subsequently. We do not have topo-maps (the availability of such maps in our country is severely limited) so I suppose unless we are doing orienteering or surveying, True North setting will be more appropriate?
Advice on this is appreciated. Thanks.
