Bottom Lock
(Sonar Zoom View only)
Settings: Off, On; Default = Off
Bottom Lock changes the mode of the zoomed view in the Sonar Zoom View.
Bottom Lock continuously graphs the bottom at a constant point on the display
regardless of changes in depth. This “flattens“ out the bottom contour but is
effective at showing fish on or near the bottom.
