I have a 60csx and it is a good unit. I mostly use a Rino 655T. The radio has come in handy a few times. If I'm hunting near the house, I leave a radio with my wife. If she needs me for something urgent, she can get me. And vice versa.
It has been very useful for keeping track of my hunting buddy, especially if we are hunting in the same vicinity. We can keep tabs on each other, primarily so we can stay out of each others way. And, when one of use needs help dragging something out, we don't need to walk a mile back to the truck.
