AIRMAR B75M 12DEGREE TILT
Single Channel CHIRP
Using pulsed transmissions swept across a range of frequencies, CHIRP technology delivers target resolution and depth penetration superior to traditional single-frequency sonar. This single channel CHIRP transducer operates anywhere in the 80-130 kHz Medium CHIRP frequency range, with a 24-16° beam width. The B75M provides an operating depth of up to 450 m (1500 ft).
One sensor does it all. Able to measure both depth and temperature in a single package, the B75M simplifies installation and requires just one connection to an echosounder module or multifunction display.
The B75M’s 12° fixed tilt is ideal for boats with an 8° to 15° hull deadrise. An untilted (0°) version is also available, and a 20° tilt to compensate for deadrises of 16-24°. With ceramic elements tilted inside the housing to aim the beam straight down without a fairing block, these transducers are able to deliver more accurate depth readings and best cover the area directly beneath a vessel's hull.
With bronze housing, the B75M is suitable for thru-hull mounting in fiberglass and wood hulls. Thru-hull mounting places the transducer in the water on the outside of a vessel’s hull; a hole must be drilled for installation. This typically offers the best depth measurement and fishfinding performance.
