Airmar B164 Bronze 12-Degree Thru-Hull Transducer

The Airmar B164 Bronze 12-Degree Thru-Hull Transducer gives you 1 kW of power in a flush-mount thru-hull with no fairing. It is built for fast, trailered boats that cannot use a high-performance fairing block. The ceramic element sits at a fixed 12 degree tilt inside the housing, which suits hulls with 8 to 15 degree deadrise. With the transducer mounted nearly flush, that tilt cancels out the hull angle and points the beam straight down for the strongest echo returns.

The 50 kHz frequency has a 22 degree beam that reads to about 1,800 ft. The 200 kHz frequency has a narrow 6 degree beam that reads to about 800 ft with fine detail. It works with any 600 watt or 1 kW sounder and includes fast-response water temperature sensing.

The housing sits less than 1/4 in below the hull, so it can ride on trailer rollers and bunks. It needs a 3-3/4 in hole, weighs about 6 lb, is made in the USA and is rated for boats up to about 36 ft. Airmar's Xducer ID technology lets a compatible fish finder recognize the transducer and set itself up automatically. This model needs a separate Airmar Mix and Match cable for your brand of display, sold separately. If you change electronics brands later, you can leave the transducer in the hull and just swap the cable. The bronze housing is for fiberglass or wood hulls, so check your hull material before ordering. A thru-hull install means drilling the hull, so many owners have it done at haul-out by a qualified installer. Other transducers are in our marine transducers section.
