Basic Sonar Quick Reference
1. Depress the
PWR
key to turn on the unit.
2. 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.
3. 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
.
4. If necessary, adjust sensitivity to improve chart readability. Press
MENU
|
ENT
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.
5. 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.
6. 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

to

.
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
.
7. If you are drifting at a very low speed or anchored, you are not mov-
ing fast enough for a fish to return the tell-tale fish arch signal. As you
drift over a fish, or as a fish swims through the transducer's signal
cone, the fish echo will appear as a straight line suspended between the
surface and the bottom.
8. To turn off the unit, press and hold
PWR
key for three seconds.
