The external module hardware, (shown in Fig. Most in-hull transducers are mounted inside a liquid filled tank that is first epoxied in place. CHIRP sonar is less susceptible to these problems, and clever processing of echoes and sonar images can mask their effects, but the key to good sonar performance is to avoid problems altogether. Sonar (sound navigation ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels. Transom mount Thru-hull mount. This fish finder comes with a dual-beam transducer that provides sonar images of target separation.
