Bottom Zoom Display - Furuno FCV-1900 Operator's Manual

1. OPERATION

Bottom zoom display

This mode expands bottom and bottom fish on the left-half window, and is useful for
determining bottom contour. When the bottom depth increases, the display automati-
cally shifts to keep the bottom echo at the lower part of the screen.
Marker zoom display
The marker zoom mode expands specified area of the normal picture to full vertical
size of the screen on the left-half window. You may specify the portion to expand by
operating the VRM (Variable Range Marker). The area between the VRM and zoom
marker is expanded. This mode is useful for determining the size of fish in the midwa-
ter.
