Like the title say of this review the best handheld GPS navigator on the market and maybe the best GPS device that famous Garmin created. They really did a good job with this one. I us it for hunting and sometimes for recreational mountainclimbing and i must say that this navigator deliver with out any problem or lag whatsoever. Operating system is great plain and simple. GPS is really accurate and buttons easy to us. This GPS has a great feel when you hold it,it's not easy to break i guarantee that for you. finally i recommend it from bottom of my hart,it's great and gets the job done like it should.
