4. VIDEO SOUNDER OPERATION 4.3 Automatic Sounder Operation Automatic sounder operation is useful when you are preoccupied with other tasks and do not have the time to adjust the display. 4.3.1 How the automatic sounder works The automatic sounder function automatically selects the proper gain, range scale and clutter suppression level according to the depth. It works as follows: • The range changes automatically to locate the bottom on the lower half of the screen.
4. VIDEO SOUNDER OPERATION 4.4 Manual Sounder Operation Manual operation is useful for observing fish schools and bottom using a fixed gain setting. The gain, range and range shift functions used together give you the means to select the depth you can see on the screen. The basic range can be thought of as providing a “window” into the water column and range shifting as moving the “window” to the desired depth. 4.4.1 Selecting the manual mode 1. 2. 3. 4. 4.4.

Water Temperature Graph The water temperature graph (appropriate sensor required) plots water temperature on the sounder display. (See the figure on page 4-3.) It can be turned on or off as below. 1. 2. 3.
4. VIDEO SOUNDER OPERATION 4.14 Interpreting the Sounder Display 4.14.1 Zero line The zero line (sometimes referred to as the transmission line) represents the transducer’s position, and moves off the screen when a deep phased range is used. Zero line Shift Zero line 4.14.2 Bottom echo Echoes from the bottom are normally the strongest and are displayed in reddish-brown, but the color and width will vary with bottom composition, water depth, frequency, sensitivity, etc.
4. VIDEO SOUNDER OPERATION 4.14.3 Fish school echoes Fish school echoes will generally be plotted between the zero line and the bottom. Usually the fish school/fish echo is weaker than the bottom echo because its reflection property is much smaller compared to the bottom. The size of the fish school can be ascertained from the density of the display. Size of fish school Small school Large school Fish school echoes 4.14.
