Figure 2-29 Horizontal/strata display

The horizontal display appears in the main window; the strata display in the sub window. The strata picture shows bottom undulations in different colors. 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. Press the [MAIN/SUB] key to select the main or sub window. 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.
