The Airmar B75C-12-L is a low-frequency CHIRP transducer with a 12° tilted element, ideal for hulls with an 8° to 16° deadrise. Designed for deep-water coverage, this bronze thru-hull model delivers outstanding performance in depths up to 1,200 ft.
Operating from 40 to 75 kHz with a wide 32° to 21° beamwidth, the B75L offers up to 35 kHz of bandwidth in a single installation. Its streamlined profile supports clean, accurate readings at speed, while the tilt ensures the beam is directed straight down for optimal returns.
Compatible with Garmin systems using 8-pin or 12-pin Mix-N-Match cables, this model is a favorite among offshore and sport fishing enthusiasts who need reliable bottom tracking and sonar clarity at depth.
