Viewing two frequencies concurrently using the split-frequency
view allows you to see deeper with the lower frequency return

sonar view.

Turning On the A-Scope
NOTE: This feature is not available in all sonar views.
The a-scope is a vertical flasher along the right side of the full-

received sonar data so that it is easier to see. It can also be
helpful for detecting fish that are close to the bottom.
From a sonar view, select Menu > Sonar Setup >
Appearance > A-Scope > On.
Selecting the Transducer Type
Before you can select the transducer type, you must know what
kind of transducer you have.
If you are connecting a transducer that was not included with the
chartplotter, you may need to set the transducer type to make
the sonar function properly. If the device automatically detected
your transducer, this option does not appear.

Automatic scroll speed adjusts the scrolling speed to the
speed the boat is traveling.
Noise Reject: Reduces the interference and the amount of
clutter shown on the sonar screen (Sonar Noise Rejection
Settings, page 19).
