Part Number: 010-00092-00


GPSMAP 135 Sounder is an innovative combination of a complete depth sounder and proven Garmin® GPS chartplotting. This ideal sounder/GPS combination will give you the advantage and convenience you want on the water without a stiff price.

The GPSMAP 135 Sounder sports features you won't find in any other depth sounder. Its four level grayscale display presents a crisp picture and unparalleled separation of fish, thermoclines, underwater structure, and the bottom. A variable zoom window allows you to view deeper or shallower water instantly. You can even mark underwater objects like stumps, dropoffs, or hazards, for future use. Take advantage of our first-ever split screen display. This useful feature gives you the advantage of viewing GPS cartography and sounder data at the same time.

If having the best depth sounder on the market isn't enough, add second-to-none navigational guidance. The GPSMAP 135 Sounder feature's the unmatched accuracy of Garmin's high performance 12-channel GPS receiver and digital G-chart cartography for chartplotting on inland or offshore waters. With Garmin on board, fishing will never be the same again.
