Setting Up and Using Sonar > Understanding Sonar 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 fish—sound is reflected back to the transducer. The transducer collects the reflected sound waves and sends the data to the GSD 20 or GSD 21 Sounder Module and then to the GPSMAP 276C to be processed and shown.
Setting Up and Using Sonar > Understanding Sonar 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 Coverage cone angles (40°) associated with low frequencies (50 kHz) provide diameter a large coverage area for finding fish within a coverage width that is approximately 2/3 of the water depth. However, this also means that wide cone angles produce less bottom detail and resolution.
Setting Up and Using Sonar > Understanding Sonar Whiteline The GSD 20 or GSD 21 can help you determine whether the bottom is hard or soft. When the sonar sound waves are reflected 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 the point where water meets the bottom.
