Tip:
For quicker sensitivity adjustments, try leaving the Sensitivity
Control Bar on the screen as the chart scrolls. You can see the
changes on the screen as you press the up or down arrows. This is
handy when there's a lot of clutter in the water, and you are match-
ing the sensitivity to rapidly changing water conditions.
Sonar Chart Mode
The default color scheme for the sonar chart is the white background,
but we offer other variations to suit your viewing preferences. The
chart can be displayed in grayscale, reverse grayscale, blue back-
ground, white background, nightview, iceview, or bottom color tracking.
