My old man and I have a Garmin Rino. They are awesome because not only do you get the gps but you get the radio function is well. It is also nice when you can send each other your locations so that you can find each other. During late bow season I got pinned down by a few cows that we feeding in the open and was able to send my location to him without having to sit and try to describe where I was. They are spendy but well worth it!
