The Simrad 38/200 Combi W is a dual frequency transducer (38 and 200 kHz), and both frequencies operate with wide beams (31°). This makes the transducer perfect for shallow water fish detection using the 200 kHz frequency, and excellent for bottom discrimination from shallow depths and down to several hundred meters using both frequencies. This is currently the only 200 kHz wide beam (31°) transducer available on the market. It has been made possible using the latest Simrad Composite Transducer Technology. This unique technology also ensures a transducer efficiency above 70%.
