I’ve had a couple different Inreach’s and I’ve always had good luck with them I currently have the 66i it’s nice having good maps and a functional gps on it. I’ve never had any problems sending and receiving msges
I’ve been using these radios the last 2 years for snowmobiling and hunting and have been able to communicate from the sled parking lot to the cabin which is 12km away and this fall hunting I was on top of one Mtn and my buddy was on another 16.4km away and we were able to talk with no problems...
