EMI Killing Your Fishing Trip?

Electromagnetic interference (EMI) is a type of interference that occurs when an electrical current or electromagnetic field disrupts the normal operation of an electronic device. On a boat, EMI can affect the performance of a transducer, which is a device used to transmit and receive electrical signals.

There are several sources of EMI that can affect a transducer, including:

• Other electrical devices on the boat: Electrical devices such as motors, radios, and GPS systems can generate EMI that can interfere with the transducer's signals.

• Lightning: Lightning strikes can generate powerful electromagnetic fields that can interfere with the transducer's signals.

• Power lines: High-voltage power lines can generate strong electromagnetic fields that can interfere with the transducer's signals.

To protect a transducer from EMI, it is important to use shielded cables and to keep the transducer as far as possible from sources of EMI. It is also a good idea to use a transducer with a built-in EMI filter, which can help reduce the impact of EMI on the transducer's performance. If you are experiencing EMI-related issues with your transducer, it is a good idea to consult with a marine electrician or the manufacturer for guidance on how to troubleshoot and resolve the issue.
