B75L Chirp-ready Tilted Element™ Thru-hull
Part NumberB75L

300 W
Airmar’s low-profile, Chirp-ready transducer models are the perfect addition to smaller boats such as center consoles. The low-frequency band, operating between 40 and 75 kHz, is a deep-water performer, providing excellent coverage and tracking. The B75L transducer delivers up to 35 kHz of total bandwidth in just one installation.
This Tilted Element™ transducer has the ceramic element fixed at either a 12° or 0° angle within the housing. When the transducer is installed almost flush to the hull, the tilt of the element corrects for the hull deadrise, orienting the beam directly down. This ensures maximum echo returns to the transducer for more accurate depth readings.
The B75L is available in two Tilted Element models:
- Fixed 12° tilted version for 0 to 24° hull deadrise angles
- Fixed 0° tilted version for 0 to 7° hull deadrise angles
This transducer is available in two options: one with an OEM connector designed specifically for your fishfinder, and another as a Mix and Match™ Transducer version. The Mix and Match™ transducer has a 9-meter (29.5’) cable with a standard connector, plus a 1-meter (3’) adapter cable to connect it to your fishfinder.
When placing your order, make sure you know which connector type your fishfinder requires.
