I’ve had a Uniden Atlantis handheld for years and it’s worked great. I can’t see spending a lot more on a handheld because the limiting factor on all of them is going to be the range.
Whatever radio you get, you have to study how to use it so you know what you’re doing. What channels do you need to use for what purposes, etc. This is NOT a free for all like a CB and no, channel 19 is NOT a generic frequency everybody uses.
Write the frequently-used channels on the back of the radio with a sharpie.
