Zoom & Zoom Bar
The Zoom in key is used to enlarge small detail, fish signals and the
bottom with its associated structure.
The 2X zoom doubles the size of all echoes on the screen. The 4X zoom
quadruples the size of the echoes. You can also turn on a zoom bar on
the far right side of the screen. This shows which echoes will be dis-
played on the screen when the Zoom commands are used.
For example, turning on the 2X zoom will show all echoes that are be-
tween the top and bottom of the 2X zoom bar. The 4X zoom will show
only the echoes between the top and bottom of the 4X zoom bar.

1. Press

again for a 4X
zoom.
2. Press

to reduce the zoom and show more of the chart.
