Oh yes, I definitely recommend them. We've been using them since back before these handy things now came out, when CB walkie-talkies were the only option. Of course the new radios are much, much better.
I have 5 of the radios, ranging from the 2-mile radios up to the 10-mile Cobra models. We always have them on. They're a very handy in case of emergencies, or if someone has a deer on the ground and needs help getting it out.
The Cobra model has the built-in weather band. I used it one day a couple of years ago when severe weather was moving into the area. I learned on the radio that tornado warnings had been posted for neighboring counties. We decided to leave the woods early. Shortly thereafter, tornadoes swept through the area. Also it has a built-in compass, which I have found very handy a time or two also.
I certainly recommend them for anyone. One of the GPS companies makes a model that is a GPS unit/GMRS Radio. If hunter #1 starts talking to hunter #2 on the radio, hunter #2 can see where #1 is at, and vice-versa. That would be very handy in the case of an emergency and I plan to upgrade before next year.
