I just received my GPS! It is the Spot Gen3. This GPS is simply a tracker and will allow me to share my location whenever I wish. I have set it up to post to this blog with my location whenever I set up camp or whenever I hit a town to pick up a resupply. There's also an SOS feature in case my life is in danger- when pressed it will send my location to the GEOS International Emergency Response Center. Glad to have this thing!
