Product Data Sheet
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.
