Garmin Fishfinder 400C Dual Beam Transom Mount Transducer

You'll spot the big ones easily on the Fishfinder 400C's crisp, ultra-bright 4" QVGA color display. A choice of dual frequency or dual beam transducers makes this a good choice for both freshwater and saltwater fishing. In the offshore setup, you'll get a true A-scope display for instantaneous sonar data. When configured for inland use (dual beam), a round flasher viewing option is provided. The 400 watt RMS dual beam version offers a wide fish-finding cone and reaches depths to 900 feet, while the 500 watt RMS dual frequency setup can go as deep as 1,500 feet. Features UltraScroll for screen updates at live-action speeds. And Garmin's plug-and-play CANet bus enables sonar data to be easily shared with compatible Garmin chartplotter displays.
