Transducers

Knudsen Engineering has a wide range of both single and dual frequency transducers available for purchase. Transducer selection is critical to the proper and optimal performance of your echosounder. Knudsen Engineering can provide full systems including single and dual frequency transducers as well as transducer arrays for maximum resolution at low frequencies. Some of our popular transducers are in stock and available for immediate delivery. Other custom combinations are available upon request.
