Garmin GT56 Transducer

The Garmin GT56 transducer is a top choice for customers pairing it with Garmin electronics. It is available as a transom mount or through-hull. For through-hull installations, a single transducer works for boats with a flat spot on the bottom with 6 degrees of angle or less. For steeper angles, a pair of transducers, one on each side of the boat, is recommended.

The GT56 operates at 150-240kHz and reaches depths of 800 feet freshwater (Roughly 600 +/- in Saltwater). Its UHD ClearVu and SideVu sonar provide exceptionally clear images of fish and underwater structures, even showing fish hanging off submerged branches. UHD ClearVu images reach 200 feet below the boat, and SideVu offers two frequency settings for a 20% greater range.

Compatible with Garmin echomap UHD 73/74/93/94sv, echomap Ultra 106sv/126sv, and GPSMAP 743xsv/943xsv/1243xsv/1643xsv, and 8400/8600xsv GPS/Fishfinder Series.
