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.
