Airmar Transducer Mounting Options

These are Airmar’s most popular CHIRP transducers. They are available in most popular frequencies, offering several sound choices compatible with your sonar equipment. Now all you have to do is determine where you plan to mount it. Airmar B265 Transducer Popular on slower (under 35 knots) inboards with the blue fairing block cut to the deadrise angle to maintain a perpendicular transmission axis. It is best mounted off the propeller ­thrust-line to avoid cavitation.

Usually used on high-performance center consoles and often fiberglassed inside a custom-built hull “pad” on the keel to shoot through the fiberglass near the transom, giving it clean water and good readings at speed.Courtesy Airmar

Airmar CM599 Transducer

Designed for through-hull mounting to keep the transducer face in contact with the water. Ideally mounted through a flat keel “pad” near the transom or set at a vertical angle into a pocket, countering the deadrise angle.Courtesy Airmar

Airmar B175 Transducer

The tilted element in this transducer allows a vertical element orientation when flush mounting at any deadrise angle, including 0- or from 12- to 20-degrees. Though the bronze fairing is slim, it can noticeably change hull dynamics on center consoles under 30 feet.Courtesy Airmar
