Understanding Sonar The transducer mounted on your vessel transmits sound waves toward the bottom of the water in a cone-shaped pattern. When a transmitted sound wave strikes an underwater object—such as the bottom, a structure, or a sh—sound is reected back to the transducer . The transducer collects the reected sound waves and sends [...]

Transducer Coverage The area covered by the transmitted sound waves is determined by the cone angle of the transducer and the water depth. The wide cone angles (40°) associated with low frequencies (50 kHz) provide a large coverage area for nding sh within a coverage width that is approximately 2/3 of the water depth. However , this also mea[...]

Whiteline The GSD 21 Sounder Module can help you determine whether the bottom is hard or soft. When the sonar sound waves are reected back by the bottom, a hard bottom returns a stronger signal than a soft bottom. A thin whiteline indicates a softer bottom, while a thick whiteline indicates a harder bottom. Normally , a red line is used to show [...]
