Garmin Fietssteun Montana/Monterra

As a powerful "handheld" GPS unit — that is likely more useful mounted on a vehicle than actually in your palm — the Garmin Montana 700 is an investment for the serious backcountry sportsman. A high resolution, 5-inch diagonal touchscreen offers superior display quality and easy access to a highly customizable set of preloaded maps, additionally supported by an unlimited subscription to Garmin's database of satellite imagery. All of this is backed up by exceptional satellite reception, a fast processor, and precise altimeter, barometer, and compass sensors. But for all of its capability, the Montana 700 is the largest and heaviest unit of any in this review, making it less versatile for backpacking or hiking. This highly capable GPS is most suitable as a mounted unit, one that will likely appeal to hunters and others who traverse the backcountry in lightweight vehicles.
