Zoom & Zoom Bar
"Zooming" the display is a common, fast and easy method used to en- large small detail, fish signals and the bottom with its associated struc- ture. This unit lets you zoom the display quickly and easily by pressing the Zoom In key, ZIN.
Pressing ZIN once doubles the size (2X) of all echoes on the screen. Pressing it again quadruples the size of the echoes (4X). When turned on, the zoom bar on the far right side of the screen shows which echoes will be displayed on the screen when the ZIN key is pressed.
