The Fishfinder 340C has 12-square-inches of brilliant color. For nighttime viewing, the 340C features an ultra-dim backlight mode. It’s available with a dual-beam transducer for freshwater use or dual frequency for saltwater applications. The 340C works with the Garmin high-speed sonar network, which means you can connect it to a Garmin plotter to view data and adjust settings from the plotter. Enhanced software features include drift alarm, timers, and a temperature log that graphically records water temperature data.

The Fishfinder 340C is also enabled with Garmin’s new CANet™—a one-megabit Controller Area Network that allows users to connect their unit to one of the new GPSMAP®-series chartplotters. This allows boaters to read sonar displays on chartplotters located elsewhere in the boat. The Fishfinder 340C is offered in either a dual-frequency configuration or, for inland anglers needing a wider fish-finding cone, a dual-beam model. Water temperature, a round flasher-style display, and an A-scope display also come standard on the Fishfinder 340C.
