Twelve square inches of brilliant color — with the Fishfinder 340C's bright color display, finding fish is easier than ever.
See Fish in Bright Color
The Fishfinder 340C has a brilliant color TFT display and ultra-dim backlight mode so you can see the screen clearly, in bright sunlight or after sundown. Choose from a dual-beam or dual-frequency transducer to optimize the 340C for freshwater or off-shore fishing. And, the 340C records water temperature data and lets you set multiple alarms, including drift alarms and timers.
Connect to Another Plotter
The Fishfinder 340C can connect to Garmin's CANet® — a 1 MB Controller Area Network that allows users to connect to one of the new GPSMAP®-series chartplotters. Once connected, you can read sonar information on the 340C from from plotters located elsewhere in your boat.
