Garmin's bronze thru-hull mount transducer performs well at high speeds and is an excellent choice for fiberglass and wood hulls. This flush-mounted housing protrudes less than a quarter of an inch outside the hull and can sit on trailer rollers/bunks without damage.
An 8-pin 1 kW transducer, it has a depth of 1,200 to 1,800 ft; an operating frequency of 50 to 200 kHz; a beamwidth of 22x20 or 6x6 degrees; and mounts on a 16 to 24 degree deadrise angle.
Transducer kit comes with installation instructions. Follow the instructions carefully to avoid damaging your boat.
Note: Do not use on metal hulls. When using with a 6-pin Garmin sounder, a transducer adapter cable is required.
