Fishfinder 400C Dual Frequency

The versatile Fishfinder 400C has a super bright, high resolution 4-inch display and is great for finding fish in both freshwater and saltwater.

Use in Freshwater and Saltwater

The 400C is available with a choice of dual beam or dual frequency transducers, so it's readily adaptable for both freshwater and saltwater fishing. With the 500 watt (RMS) dual frequency transducer, you can reach a depth of 1,500 feet.

Connect with CANet

Fishfinder 400C features a crisp, ultra-bright 4” QVGA color display, plus UltraScroll for screen updates at live-action speeds. It's also CANet-compatible, so you can share sonar information with plotters located elsewhere in your boat.
