Frequency to Dual, you can access the Split Sonar Page, the Sonar
(220kHz) Page, the Sonar (50kHz) Page, and its related Adjustment

Split Sonar Page with
Adjustment Menu
For all Sonar Pages, the currently selected adjustment option (page
36) appears in the upper-left corner of the screen. Directly below
the adjustment option, the screen shows numeric data, such as
Depth, Water Temperature, or Water Speed, depending on your
settings (see page 39). The middle of the page contains a right-
to-left moving sonar image of the water beneath your boat. Items
appear as they pass under your transducer. Items on the right side
of the screen are closer to you than those on the left.
