The transducer is a hardware that can transmit ultrasonic waves and receive the reflected
ultrasonic waves. The echo sounder is to use the ultrasonic waves speed and the delta t between
the transmitting wave and reflected wave to calculate the depth of water.
Transducers are divided into single-frequency and dual-frequency according to the purposes or
applications, since SDE-28S+ is a single-frequency echo sounder, it is equipped with the single-
frequency transducer.
