Where does one get one of these? I take it they are small enough to fit inside, and innocuous enough that the thief (and or buyer) is unlikely to notice it....or at least notice it quickly? I lost an 8 horse Yammy a couple years ago, and now have several "security devices" attached to my new one, and a light and trail cam for when the inevitable low lifts come by to take a look in huge middle of the night, but the GPS tracker is a fabulous idea.
