Garmin Transducer Adaptor Cables | 4-pin, 8-pin & 12-pin Connectors

Garmin Transducer Adaptor Cables

Ensure a reliable connection between your Garmin chartplotter or fishfinder and your Garmin marine transducer with a genuine Garmin transducer adaptor cable. We stock a wide range of Garmin adaptor cables designed to connect different sonar connector types, including 4-pin to 8-pin, 6-pin to 4-pin, 8-pin to 4-pin and more.

Garmin marine electronics use several different transducer connectors. If the plug on your transducer does not match the sonar port on your chartplotter or fishfinder, an adaptor cable allows the two devices to work together. These cables carry power and/or sonar data depending on the model.

We also stock a comprehensive range of Garmin marine power cables and other marine accessories.
