Personally, I swear by Rino GPS/Radios combos. They are a little steep in price, but you only have to lug around one piece of eqpt, instead of two and if you and a hunting pertner have them (up to eight) you can see where they are on your screen and vice versa. Check out the Rino 530 for the top of the line model. I hunt with Rino 130s and use them a bunch at work They actually saved one of my troops not too long ago. He rolled a Polaris Ranger 6 wheeler and got pinned under it. He was able to radio us and "beam" his location to get us to him to pull it off of him. GREAT product.
