I see SPOT just a new device for Marine Anti-Theft & Detection. I suppose this could be used on any vehicle, though.

"UNAUTHORIZED MOVEMENT NOTIFICATION
By establishing a virtual security perimeter around your boat, SPOT HUG detects Unauthorized Movement when your boat moves more than 500 meters without your authority and the key FOB is not present. A notification with the GPS position is automatically sent to the Asset Monitoring Center who alert local authorities (where available)."

This does not seem to be an anit-theft device, more of an alert system. In my case, when my plane moved more than 500 meters it was in the air and going someplace unknown without me!! Now, if the device could track the vehicle and enable lawenforcement to arrest the pricks and return the plane, that would be worthwhile.

Now there's a good story worth a post... go on with the details on how you had your bird fly on its own!
