The GPSMAP 235 Sounder really offers three products in one: a GPS receiver, a chartplotter, and a fishfinder. You won't need to duplicate technology to enjoy your sport to its fullest.

This unit features dual-frequency operation that provides a clear image in both deep and shallow water—1,200 feet in saltwater and freshwater—all from one transducer. Garmin's exclusive See-Thru® technology lets the GPSMAP 235 Sounder hear both weak and strong signals at the same time, giving it tremendous dynamic range. The result is a 4-level grayscale display that shows strong fish returns even when fish are inside structure and thermoclines. Over 25 square inches of active viewing area gives you sizable detail coverage. The backlit screen measures an impressive 7.25" diagonally, yet the unit itself is slim enough—a mere 2.57" deep—for discreet and easy bulkhead flush mounting. A variable zoom window allows you to view increased detail at the touch of a button. You can even mark underwater waypoints to capture the position and depth of objects like reefs, dropoffs, or hazards and permanently store them for future use.

The GPSMAP 235 Sounder: It's everything you need for fishing in any condition.
