MichiganMan: "I'll second the Motorola Talkabouts. See here: https://www.cabelas.com/SearchDisplay#q=motorola%202%20way%20radios
I spent a little more and got the waterproof ones. They've served us very well for several years."
After one of our radios got left in the canoe and it rained on it so it quit working, we started putting them in ziplock bags. Waterproof and you don't have to take the radio out to talk.
