Product Overview

Airmar B75C-12-M 12d Tilt Medium CHIRP with Navico 9-Pin Mix-N-Match Cable

Model: B75C-12-M-9N
  • 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.

Expert Overview

The Airmar B75C-12-M-9N is a bronze, thru-hull transducer designed for marine applications, specifically for boats up to 8 meters (25 feet) in length. This unit provides both depth and fast-response water temperature sensing. It operates within a Medium CHIRP frequency band of 80 kHz to 130 kHz, offering 50 kHz of total bandwidth from a single installation. This frequency range includes popular fishing frequencies such as 88 kHz and 107 kHz. The transducer features a 12-degree tilt angle, which corrects for hull deadrise between 8 and 15 degrees, ensuring the beam is oriented directly downwards for accurate readings. It is suitable for fiberglass or wood hull types and has a 600W power rating. The included Navico 9-Pin Mix-N-Match cable is 9 meters (30 feet) long. This transducer is intended for IT professionals or procurement managers sourcing marine hardware for smaller vessels requiring detailed bottom information in shallow to medium depths, down to 274 meters (900 feet).
