[. . . ] The length of the picture displayed in the history display is equal to about four full circle pictures. Thus the history display enables you to observe the history of fish movement and distribution. It is also useful for detecting bottom fish, reefs and sunken vessels. The history display cannot be adjusted. 2-28 Horizontal/video plotter display Press the key to display the horizontal/video plotter display.

Compared to the horizontal display the video plotter's range is much longer. For example, an event marker entered on the horizontal display disappears from that display when it goes out of the current range. However, it remains on the video plotter display for a much longer time when a long range scale is used. This can be useful when you want to return to the location denoted with an event marker. The video plotter scale can be changed (setting range: 500-5, 000 meters) with "TRACK DISP" on the RANGE-SONAR MODE menu. The video plotter display cannot be adjusted. 2-29 Horizontal/strata display Press the key to display the horizontal/strata display.

This is useful in bottom trawling to avoid projections which may damage the net. Coverage for the horizontal mode is 360° picture, and for the strata display it is maximum 90° from port to 90° starboard. The strata display may be adjusted with the [RANGE] and [SECTOR] controls. The message MAIN WINDOW CONTROLLABLE or SUB WINDOW CONTROLLABLE appears with each pressing of the key. A red cursor appears in the sub window when it can be controlled. 2-30 Color bar for the strata display The depth of the bottom echo in all directions is displayed in the sub window, in the colors set by the color bar for the strata display. Strongest color Weakest color -90° -18° -12° -6° 0° 6° 12° 18° 90° Color bar for strata display The undulation of the bottom echo in all directions is shown by the colors on the color bar for the strata display. The position of the weakest echo can be changed with the [RANGE] control, and the width of each color on the color bar for the strata display with the [SECTOR] control. Use the [SECTOR] control to adjust width of each color. Weakest color Use the [RANGE] control to move the location of the weakest echo color. Note: TILT, TRAIN, FULL/HALF, FAST SCAN, R/B, EVENT, TARGET, CUSTOM MODE controls may only be operated from the main window. When you attempt to operate them from the sub window the message "SELECT MAIN WINDOW. " appears for about four seconds. Flat bottom and strata display Each layer on the strata display is equal to one train on the horizontal display.
