I have 2- Handhelds radios that I always keep charged- one we take out for the day and leave on channel 16 or 14 if you are near a L/D. The newer radios have weather channels w/alerts so you can keep-up with the weather. The range can vary, out in the wide out pools(lakes) you can get 3-4 mi., around the bends with the high bluffs, maybe 1-2 mi. Or, if you have an emergency you can use 16 and call for help. We don’t go out on the water without one. Hope this helps. – John oh, yes, the second radio we use if we are fishing with another boat and as a back-up.
