I have a Spot trace 100% gps. Cost 119.00 for the device and 99.00 per year contract. It sends it location every 5 minutes to a gps sat witch sends your position to a comm sat then to your cell or internet. The spot does not need cell service and will track all north america and in many other countries. I just made a long trip in my car, had the device fall upside down in the back under a blanket and it still tracked my trip. 185 grams is considerable and I use it on my P4 when I feel the need. I modified a trakimo holder to mount on my bird, so far so good. I plan to use it on my snowmobiles next winter so my kids will know where I am, I live in northern Ontario and cell service is not all ways available.
