Garmin 77/200 kHz transom transducer with a four-pin connector. Availability and terms on request.

Garmin transom transducer with traditional 77/200 kHz sonar and a four-pin connector. The two frequencies support sonar-view selection according to the sounder and operating situation.

Is this transducer compatible with my sounder?

Check the sonar model, connection, desired functions and mounting location. Matching pin counts alone do not confirm every integration capability. Share your installation to review adapters where applicable, cable routing and positioning with Wonder BOAT.
