I have a Garmin Rino 110 FRS/GMRS w/ GPS I carry on hunting trips. One of the features I have yet to use allows another Rino user to read your GPS coordinates on their unit while you are transmitting. If I were lost while hunting, I would hope the authorities would be monitoring all those channels. I wonder if they have specialized equipment that allows them to receive my signal at a greater range than another Rino user would?
