Switchfire; Freeze Frame And Active Cursor; Instant Image Update - Humminbird 748 3D Operation Manual

SwitchFire™

SwitchFire™ controls how the sonar returns are displayed in the Sonar Views.
SwitchFire™ settings are available in the Sonar Menu Tab.
To see the maximum sonar information available within the transducer beam so
more fish arches and better jig tracking are shown, choose Max Mode.
To see less clutter and more fish size accuracy interpreted from the transducer
beam, choose Clear Mode. See Sonar Menu Tab: SwitchFire™ for more
information.

Freeze Frame and Active Cursor

and a cursor will be displayed. Use the 4-WAY Cursor Control key to move the
cursor over a sonar return, and the depth of the sonar return will be displayed
in the cursor dialog box.
NOTE: In 2D Sonar Views, the RTS Window™ continues to update in Freeze Frame.
To return to a scrolling display and exit Freeze Frame, press the EXIT key. Freeze
Frame is available in the Sonar and Sonar Zoom Views.
