Behind Every Successful Depth Sounder Is A Great Transducer
Part 1

What is a transducer?

Wikipedia says: “A transducer is a device, usually electrical, electronic, electro-mechanical, electromagnetic, photonic, or photovoltaic, that converts one type of energy or physical attribute to another for various purposes including measurement or information transfer.” Examples of common transducers are microphones and speakers. Just consider the transducer for your depth sounder to be a combination of both. When the depth sounder transmits a signal the transducer coverts the electrical energy into acoustic energy, like a speaker. In the receiving mode the transducer reverses the process and converts the received acoustic energy back into electrical energy, like a microphone. Once you draw the comparison it’s much easier to understand just how the design and quality of the transducer effects the performance of the sounder. Even the very best depth sounders are no better than the quality of the transducer it’s connected to. If it’s not starting to glow yet, as you learn more about transducers that light will go on that tells you maybe I should have been paying more attention to what transducer I selected with that new sounder. Stay tuned for the next exciting entry, “How a Transducer Works.”
