Use the 4" sunlight-readable dual-orientation touchscreen of the Garmin Montana 610 Handheld GPS guide you on your next excursion. You can choose between landscape and portrait modes for the best possible view of the map or data you are trying to interpret.

This unit utilizes both GPS and GLONASS satellites for quicker signal acquisition so you get a fix on your position approximately 20 times faster than GPS alone. The receiver also can interpret Wide Area Augmentation System (WAAS) signals so you can receive information from terrestrial antennas even when your view of the sky is obstructed. The WAAS system also provides greater position accuracy overall. HotFix satellite prediction cuts down on initial signal acquisition by approximating their positions.

The unit's built-in 3-axis tilt-compensated electronic compass shows your heading even while standing still, no matter how it is positioned. It also houses a barometric altimeter which tracks changes in pressure to pinpoint your precise altitude so you will know your distance from sea level. The GPS comes with a rechargeable battery, or you can use AA batteries.
