Here’s How the Montana Models are Different

The Montana series are large, dual-orientation touchscreen GPS navigators good for hunting, hiking, boating, ATV and other outdoor adventures.

The new Garmin Montana 700 series was released in August 2020 and features rugged military-grade construction, TopoActive maps, direct-to-device downloads of BirdsEye Satellite Imagery and dog tracking.

The Montana 700i and 750i also adds two-way messaging via the global Iridium satellite network (subscription required). If you are looking for a smaller, lighter device that also accepts AA batteries on the fly, consider the Montana 610 or 680.

If you are looking for a larger screen, preloaded TopoActive maps, Expedion mode for an ultralow-power GPS reference, consider the Montana 700.

For two-way satellite communication capabilities, the Montana 700i and 750i (with 8MP camera) are your choices.
