Basic Sonar Quick Reference
1.Mount the transducer and unit. Connect the unit to electric power and the transducer.
2.Launch your boat.
3.To turn on the unit, press and release PWR key.
4.Head for your fishing grounds. Your unit automatically displays digi- tal depth and surface water temperature in the corner of the screen.
The auto settings will track the bottom, displaying it in the lower por- tion of the screen. The full sonar chart will scroll from right to left, showing you what's under the boat as you cruise across the water.
5. As you're watching the sonar returns, you can change the display by:
Zoom in to enlarge the chart for more detail: press ZIN.
Zoom out to return to full chart mode: press ZOUT.
6.If necessary, adjust sensitivity to improve chart readability. Press MENUENT and the Sensitivity Menu will appear on the left of your screen. Use ↑ and ↓ to change the setting.
Boosting sensitivity will show more information on your screen, which may cause clutter. Reducing sensitivity will filter out some informa- tion, but could omit important images. We recommend adjusting sensi- tivity until the background is lightly "peppered" — that is, scattered dots appear, but individual objects (like fish arches or bottom struc- ture) can be easily picked out of the background.
7.Watch the display for the appearance of fish arches. When you see arches, you've found fish! Stop the boat and get your lure or bait into the water at the depth indicated on the sonar chart.
8.Gauge the fish depth by visually comparing the fish arches with the depth scale on the right side of the screen, or get a more accurate measure with the Depth Cursor. Press MENU↓ to DEPTH CURSORENT. Press ↓ (or ↑) to align the cursor line with the fish arch. The exact depth appears in a box at the right end of the cursor line. To clear the cursor, press EXIT.
9.If you are drifting at a very low speed or anchored, you are not mov- ing fast enough for a fish to return the
10.To turn off the unit, press and hold PWR key for three seconds.
