I checked with the local sheriff's station and was told they have no preference. They did warn that a false sense of security comes with those devices. I agree. We did look at onstar but it's part of the car - even the type you purchase and add on and we're looking for something more independent. I changed my original post as I went back and looked at the SPOT reviews. Even went further online and read some more about it. I may give it a try after all. It offers the chance to send my position to loved ones as I travel and that seems nifty.

Thanks all for your input. I'll update once I make the final decision and try whatever it is out in the woods.
