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.
