With routable mapping for roads and trails, the Montana 700 handheld brings advanced outdoor features into a sturdy 5 format that's ideal for navigation on foot, bike, kayak, ATV and more. Access to GPS, GLONASS and GALILEO satellite networks enables Montana 700 to track in more challenging environments than GPS alone. The LiveTrack feature lets you wirelessly connect your device with other compatible Garmin GPS users, so they can follow your tracks, routes, waypoints and adventures. An internal, rechargeable lithium-ion battery pack provides more than 18 hours of battery life in GPS mode. It can also be powered with traditional AA batteries.
