This is for the display and a Dual frequency transom mounted transducer. Ideal if you looking to upgrade to the latest state of the art fish finder.

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.
