Beartooth has been trying for 2-3 years now. First it was going to be frs/gmrs. Then there was also going to be an amateur radio version. The fcc shot them down on the frs/gmrs because of the antiquated rules stating analog communications only. (Garmin got a variance allowing digital location information on the rino.) So, now beartooth is in the 900mhz band and evidently claiming 10mi. I dont see getting that kind of range in the backcountry. And having it bluetoothed to your smart phone? How does that work? Do you have to use it as if you are making a phone call? No option for a speaker mic.
My sled location/communication is, smart phone in airplane mode running backcountry navigator and a cheap chinese radio (baofeng) on an frs channel, in my pack with a speaker mic on my shoulder strap. If it gets bad enough that I have to use gps to find someone, he better be able to read his coordinate to me over the radio.....
Having said all that, there is a radio that will send gps info everytime it transmitts audio. But, all it gives is coordinate. If it would display direction and distance, I'd be all over it. Tyt md-380 gps. It is digital and will be some difficult from a radio neophyte to setup.....
