Does anyone use GMRS radios for communication, or does everyone use marine VHF exclusively? I'm wondering, as there are limitations on marine VHF communications and use on land, and limited channels. If people use GMRS, I'd be curious to know how they compare to marine VHF for range, interference, and general usefulness. Any model; recommendations would be appreciated.
