With its 240 x 240 pixel, four-level gray scale screen, the Fishfinder 240 is clearly the right choice for serious anglers. With more vertical pixels, the 240 provides better separation of fish on the display. And more horizontal pixels represent more history for bottom trends.

A convenient control bar makes it easy to adjust gain, range and zoom. So without hunting through complicated menus, you can quickly configure and save the settings you want., and an internal backup system saves your settings. As lake conditions change, you can fine-tune your Fishfinder 240 on the fly. Thanks to the Fishfinder 240's See-ThruT technology, fish have no place to hide. This technology separates fish from thermoclines and structure, giving you a clear picture of what's beneath your boat.

Another exclusive feature is Depth Controlled Gain (DCGT), which automatically adjusts Fishfinder sensitivity according to depth, not echo intensity like other fishfinders. The result is a much more detailed and accurate picture of bottom structure.

NOTE: A transducer is required for operation of the FishFinder 240. A plastic, transom mount transducer with depth and temperature as well as a separate speed sensor is supplied with 010-00169-01. If you wish to use another type of transducer you could purchase the FishFinder 240 without a transducer (010-00169-00) and pair it with one of GARMIN's range of single-frequency transducers.
