I've used the Rinos with my two hunting partners for 5 years now and they have worked great. The GPS and particularly the buddy location feature on the map screen is terrific. Easy to go straight to your partner to assist with their downed animal or pick a location for everyone in your party to meet at. That being said, we all have found the radio feature to be VERY LACKING. So much so, that this year, we ended up buying the new Midland waterproof 26 mile GTX-850 radios, just for radio communication. Perhaps the new versions of the Rinos have improved their radio reception, but our (the 130s I believe) were all very difficult to communicate with. Just my .2 cents.
