Airmar B75C-20-H-MM 600W High Frequency CHIRP Thru-Hull 20-Degree Mix and Match

Low-profile tilted through-hull single-band 600W CHIRP fishfinder transducer.

The B75C is available with zero, twelve or twenty degrees tilt in the High (H), Medium (M) or Low (L) bands. There is no 20 degree Low band model.

Base Models

These Mix and Match base models must be combined with a Mix and Match cable for installation. The suffix '-MM' in the Gemeco part number designates a Mix and Match base model.

Mix and Match Cables

This transducer uses the CHIRP Mix and Match system. Installation requires two parts - a base model plus one of the CHIRP Mix and Match (MMC) cables listed below.

Each base model has a 9 meter pigtail cable permanently attached. This cable ends in an Airmar 11-pin female connector. The Mix and Match cables are 1 meter long and have a male Airmar 11-pin connector at one end (to connect to the transducer pigtail) and a brand-specific connector at the other end (to connect to the sounder or fishfinder). If an owner changes their fishfinder or sounder, a different MMC cable can be installed without disturbing the transducer itself or needing to re-run cable through the boat.
