Check out the "Rino" Along w/ the gps it has the 2 mile and the 5 mile 2 way radio in it. Waterproof in case yer digging yerself out of a waterhole and drop it and has a auto locator of other people who have "Rinos", so you and all yer buds who have them can keep track of where the hell ya lost eachother at and can find each other so yas can be lost together then drink more beer till u don't care :drinkbud . (Where the hell did all that come from?) :wtf :shrug You can do all sorts of neat things w/ them. l think you can do all the computer down loading stuff also.Thought l'd put in my 2 denars..
