I buy this unit for hike and hunting in the Rockies . like other reviewer have say there be alot to like about it . Garmin do a great job of packing 10 lb of stuff in a very small package . but , there be some negative to point out . the button and user interface software be the weakest point . because the unit be small , the button be on the side except for the `` click stick '' . I have a hard time use the `` stick '' with glove on and invariably push down when I mean to push to a side as a example . I also have a hard time press the small side button with glove on . I find some of the screen and menu option counterintuitive but learn to navigate they after several mis-step . battery usage be high . screen size be small so this probably be not a unit you want to use in a vehicle .
