Product Overview

Airmar B75C-12-M 12d Tilt Medium CHIRP with Garmin 12-Pin Mix-N-Match Cable

Model: B75C-12-M-12G
  • Depth & fast-response water-temperature sensor
  • Medium—CHIRPS from 80 kHz to 130 kHz, 24° to 16° beamwidth
  • Hull Type: Fiberglass or wood
  • 50 kHz of total bandwidth from one transducer
  • Covers popular fishing frequencies of 88 and 107 kHz plus everything else in the bandwidth
  • Bronze transducer housing
  • Boat Size: Up to 8 m (25’)
  • Exclusive Xducer ID® technology

Airmar’s low-profile, Chirp-ready, transducer models are the perfect addition to smaller boats such as center consoles. Operating at a frequency range of 80 to 130 kHz, the B75M delivers up to 50 kHz of total bandwidth in just one installation. This transducer shows amazing bottom detail in shallow and medium depths down to 274 m (900').

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 and more accurate depth readings.
