Transducer Design Underwater transducers are typically made from piezoelectric materials material s (notably crystals such as lead zirconate titanate and certain ceramics) that generate an electric potential in response to applied mechanic stress and produce a stress or strain when an electric field is applied. The transducer is protected within an oil-filled, pressure compensating dome. Most sonar transducer research focuses on the electrically active materials and their response to a variety of conditions. Since the sonar signal "fans out" in a conical shape, the transducer can be mounted pretty much anywhere on the kayak - especially since it is a boat that is less than 14' in total length. We also offer various electronic amplifiers capable to drive different capacitive loads in various frequency ranges for Sonar, NDT and SHM applications. Again, we were the pioneer in sonar technology with the creation of the AlumaDucer. Hence for a higher rectifying efficiency of 80% or above, we are going to use full wave rectifier.

The detection of depth range is from 3ft(1m) to 328ft (100m) below fishing sonar transducer. The reason for this was twofold: it was simpler to put the transducers in fixed positions, or manually steered by the user, rather than scan them around; and the type of DSP needed to disentangle the reflected clicks into shapes wasn't yet miniaturized. CHIRP Sonar and Transducer. Available in 7-, 9-, 12- and 16-inch displays. Built-in Garmin Quickdraw™ Contours mapping software lets you create and store maps with 1' contours for up to 2 million acres. Design Criteria In the past few decades, factors deciding which transducer to use were simply based more on basic primitive transducer characteristics. A sound wave travels from the transducer through the water column and returns a signal, which it bounces off an object in the water. This provides a keen awareness of fish targets relative to the transducer, and your lure; also helps prevent adjacent (non-MarCum) sonar users from picking up interfering LX-7 pulses by avoiding the “footprint” area.
