Like the Fishfinder 160 Blue, the Fishfinder 240 Blue offers offshore anglers 4,000 watts of power peak to peak (500 watts RMS) and dual frequency (50/200 kHz) for shallow or deep-water performance. The Fishfinder 240 Blue boasts a high-resolution, 240x240-pixel count on a four-level grayscale display. And, like all GARMIN fishfinders, it utilizes our patented See-Thru technology to detect weak and strong signals that allow the angler to see fish in structure and thermoclines. The unit’s graphic whiteline provides a clear picture of the bottom hardness and contour.

NOTE: A transducer is required for operation of the FishFinder 240 Blue. A plastic, transom mount transducer with depth and temperature and a separate speed sensor is supplied with 010-00219-01. If you wish to use another type of transducer you could purchase the FishFinder 240 Blue without a transducer (010-00219-00) and pair it with one of GARMIN's range of dual-frequency transducers.
