I have a Magellan 315 and suffered exactly the problem you describe.To the best of my knowledge there is no way of 'calibrating' it as such. To check you have the correct Datum set do the following: Press 'MENU' button Select 'SETUP' Select 'MAP DATUM' Select 'PRIMARY' Ensure that WGS84 is highlighted. Hope this helps you. motley. adj. varied in appearance or character. crew. n. group of people. To start with... this MAP DATUM was somehow set to the value "KKJ" which is a system used in Scandinavian charts. We'll see if this helps.

To "jtice"... I followed very thoroughly all "best practices" advice given out for newbies in this racket. Staying put over 5 minutes was one of them, machine claimed to be on 2M accuracy, procedure was repeated several times and so on... With my Magellan 320 I can find the spot just the place i left it, but nobody else can and I cannot find anyone elses caches without help of "luck-extreme". My place is not off by 100 feet but more than 100 meters (about 300 feet). To "Motley Crew" I don't know if this MAP DATUM setting is set to the value you mentioned but I'll check it. To All I'm not quite sure what "re-innicilized" mean, but if there is some method of calibrating the unit, I'll be thrilled to learn about it.

Is there any possibility to calibrate a Magellan 320 unit to give me readings that can be shared with other unit owners. So far I have hidden one cache upon which several others have complained that the coordinates I've put out lead into middle of a lake. With my unit the readings are ok and I can find the place correctly. Me and my family were looking for a cache that had several "legs" with hints that required some maths from one place to another. From that we discovered that a known starting points coordinates read out quite different with my GPS unit. Both longitude and latitude were well of the mark by more than 100 meters. Is there any way of mending this behaviour of my GPS unit or shall I toss it into river and never buy Magellan (Thales) product again?
