You can update how quickly the transducer sweeps back and
forth. A faster sweep rate creates a less detailed image, but the
screen refreshes faster. A slower sweep rate creates a more
detailed image, but the screen refreshes more slowly.

sonar view.

Calibrating the Compass
Before you can calibrate the compass, the transducer must be
installed on the shaft far enough away from the trolling motor to
avoid magnetic interference, and deployed in the water.
Calibration must be of sufficient quality to enable the internal
compass.
NOTE:
To use the compass, you must mount the transducer on
the shaft. The compass does not work when you mount the
transducer on the motor.
NOTE:
Compass calibration is available only for transducers
with an internal compass.
You can begin turning your boat before calibrating, but you must
fully rotate your boat 1.5 times during calibration.

helpful for detecting fish that are close to the bottom.

Interference: Adjusts the sensitivity to reduce the effects of

improvement should be used to remove interference from the

best way to eliminate interference.
Color Limit: Hides part of the color palette to help eliminate
fields of weak clutter.
By setting the color limit to the color of the undesired returns,
you can eliminate the display of undesired returns on the
screen.
Smoothing: Removes noise that is not part of a normal sonar
return, and adjusts the appearance of returns, such as the
bottom.
