Public Land Boundaries
Optional display of federal public land boundaries on topographical maps helps you know that you’re venturing where you’re supposed to be.
Use direct-to-device downloads of BirdsEye Satellite Imagery (no annual subscription required) to see photo-realistic views and create waypoints based on landmarks.
Navigate your next trail with ABC sensors, including an altimeter for elevation data, barometer to monitor weather and 3-axis electronic compass.

For hunters and trainers, this Montana syncs with compatible Astro® or Alpha® series handhelds (sold separately) to help track sporting dogs in the field.
Access to both GPS and Galileo satellite networks enables Montana 750i to track in more challenging environments than GPS alone.
Using your web-based MapShare™ trip-sharing page, followers can see your progress, ping your device to see your GPS location and exchange messages during your trip.
