GPS 120

Part Number: 010-00084-00


Whether you've been waiting to replace your fixed-mount loran or just want to outfit your boat with the best full-sized value in GPS, there's some good news waiting at your favorite marine dealer: the GPS 120.

The GPS 120 features a large, 4.25" diagonal backlit display and the same friendly operating software as our popular GPS 45. Take advantage of 250 waypoints, 20 routes, and a graphic highway to guide you back to the dock. Just add a differential antenna for better than 15 meter accuracy. And it's all packed in a rugged case with common-sense design and an easy-to-use button configuration.

With large, easy-to-read navigation displays and a dedicated Man Over Board (MOB) function, the GPS 120 is an ideal navigation solution for mariners who want more than a handheld—without the cost, complexity, and excessive size of typical fixed-mount units.
