Zoom & Zoom Bar

Zooming the display is a common, fast and easy method used to enlarge small detail, fish signals and the bottom. 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 dis- played on the screen when the ZIN key is pressed.

To turn on the zoom bar, press MENU↓ to SONAR FEATURESENT. Press ↓ to ZOOM BARENTEXITEXIT. Repeat these steps to turn it off.

For example, pressing the ZIN key once will enable a 2X zoom which will show all echoes that are between the top and bottom of the 2X zoom bar. Pressing the key again will give a 4X zoom and only the ech- oes between the top and bottom of the 4X bar will show on the screen. Press the Zoom Out key, ZOUT, to return to the normal display mode.
