How to choose this product
depth-transducer

The depth transducer calculates the distance separating it from the seabed and sends the measurement to an electronic device with displays the results on a screen.

Applications

These sensors are essential elements of depth sounders, highly useful devices for sailing in shallow waters with rocky bottoms, channels with shifting sandbanks or in similar situations. They also can be used for finding fish or to determine the amount of chain to pay out based on the depth of the anchorage.

Technologies

The transducer bounces ultrasound signals off the seabed at regular intervals and measures the return time of the echo. Made of bronze or plastic, the device can be part of a through-hull fitting, mounted to the hull's exterior or at the stern. Some operate on several frequencies, permitting analysis of seabed layering, while broad- or multi-beam units simultaneously examine a wide swath of the bottom, often at significant depth.

How to choose

Choice will depend on the instrument's make, connector type and functions, including dual or triple frequency and possible inclusion of a graphic readout. Mounting system is another factor. Through-hull fittings are not recommended for metal hulls, while a stern mount is most suitable for small power vessels.
