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 Mix and Match system. Installation requires two parts - a base model plus one of the Mix and Match 1000W cables (MM1) listed below.

Each base model has a 2 meter pigtail cable permanently attached. This cable ends in an Airmar 9-pin female connector. The Mix and Match cables are 8 meters long and have a male Airmar 9-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 MM1 cable can be installed without disturbing the transducer itself.

Gemeco sells kits containing a base model and a Mix and Match cable. For example, the B260-8G kit contains a base transducer and an MM1-DST-8G cable.
