Choose your fish finder, then the transducer, forward-facing sonar unit or trolling motor you want to connect. If the two need an adapter cable, the tool shows which one, with its part number.
Why Adapter Cables Matter
Fish finder brands use different plug shapes and pin counts, and some change connectors between product generations. An adapter cable can sometimes bridge the gap, but only when the sonar formats also match. A cable that fits the plug is not proof that the sonar will work, so always check the result here before you buy.
When There Is No Record
If the tool has no record for your pair, it means we have not found a documented answer yet. It does not mean the parts are compatible. Check with the manufacturer, or tell us the models through the contact page and we will look into it.
