Product Overview

Airmar B75C 12d Tilt Medium CHIRP with Raymarine 11-Pin Mix-N-Match Cable

Model: B75C-12-M-11R

  • Depth & fast-response water-temperature sensor
  • Medium CHIRP frequencies from 80 kHz to 130 kHz with a beamwidth of 24° to 16°
  • Suitable for fiberglass or wood hulls
  • Delivers 50 kHz of total bandwidth from one transducer
  • Covers popular fishing frequencies of 88 and 107 kHz along with the full bandwidth
  • Durable bronze transducer housing
  • Optimal for boat sizes up to 8 m (25')
  • Exclusive Xducer ID® technology for precise readings

Airmar's low-profile, Chirp-ready transducer models enhance smaller boats like center consoles. With a frequency range of 80 to 130 kHz, the B75C offers up to 50 kHz of total bandwidth in a single installation, providing exceptional bottom detail in shallow and medium depths, reaching up to 274 m (900').

When semi-flush mounted, the tilt of the transducer element corrects for hull deadrise, aiming the beam directly downward. This design maximizes echo returns and ensures more accurate depth measurements.

Expert Overview

The Airmar B75C 12d Tilt Medium CHIRP transducer is designed for marine applications requiring accurate depth and water temperature data. This unit operates within a medium CHIRP frequency band of 80 kHz to 130 kHz, offering 50 kHz of total bandwidth. It is suitable for integration with Raymarine systems via an 11-Pin Mix-N-Match Cable. The B75C-12-M-11R features a durable bronze housing and is recommended for fiberglass or wood hulls on boats up to 8 meters (25 feet) in length. Its 12-degree tilt angle is engineered to correct for hull deadrise between 8 and 15 degrees, ensuring the beam is directed vertically for optimal echo returns. This transducer provides detailed bottom information in shallow to medium depths, with a maximum depth capability of 274 meters (900 feet).
