Transducer is one of the most important parts of any fish finder. A bad transducer again affect the final results of your fish finding experience. The first step in this regard is detecting the issue, and then finding its root cause.

There are a few simple steps you can follow to spot a bad fish finder transducer. Let’s go through these simple steps.

Working of a Transducer

Transducer converts electricity into waves, throws them in water, receives them and converts them back into electrical signals and displays them on your fish finder’s screen when you’re trying to catch fish.

The waves sent by the transducer hit with fish and rocks in their way, and are transmitted back to your device. This is a how fish are detected under water.

Checking Your Transducer

You can easily check your transducer by seeing if it is still making its waves. Usually, when you turn it on, the device starts making vibrations. So, you can touch the surface of a transducer and feel if it’s still vibrating.

Secondly, you can check the transducer in water by turning it on in water whose depth you already know. In a static position, turn the device on and see whether it is sending and receiving signals or not.

If your transducer is working, you can now use it in water while moving. On the other hand, if the device doesn’t work, you’ll have to run a few other tests.

Aging Transducers

Just like any other piece of equipment, the transducer of your fish finder can also wear out over time. This is especially true if you use the transducer for long periods of time.

Certain crystals are used by transducers to convert electric and acoustic signals into each other, these crystals can wear out over time, and can reduce the efficiency of the transducer with them.
