RDNEK brought up the use of radios for backcountry travelers in the "Backcountry Rescue" thread.
Does anyone use them on the river? If so, does anyone have a suggestion for a waterproof radio that has a long battery life?
I am teaching my kids how to kayak. They are 7 and 9 (6 and 8 last season). We kayaked the Roaring Fork and the Grizzly section on the CO a bunch last summer. My youngest is a boy with a mind of his own. A few times his sister would swim, I'd be helping her out and he would be headed downstream oblivious to what was going on.
It would be nice if I had a radio in his life vest so I could tell him instructions. Sometimes the noise of the train, highway or river make it hard to yell.
Any radio users out there?
