Hi, heard a little bit about tracking people/GPSs using SPOT, and looking at the PBW double attempt thread there's a link to the SPOT website and the GPS log.
Can this work on any GPS (I have a crap Magellan thing that seems incompatible with any software), or do you need a specific SPOT enabled GPS? Or is it not GPS at all, but phone or something else based?
Anyone got some easy to understand guide to SPOT that they can post on here?
Do I need to use SPOT to justify a new GArmin 800 GPS?
