Bottom Lock
7. Using Bottom Lock
Factory Setting: Off
Bottom-Lock provides an up-close view like Zoom Range, except that in
this case the zoomed view automatically moves up or down to stay on the
bottom. To use this feature, select BOTTOM LOCK and press ON-OFF.
The range of the display is shown when Bottom-Lock is on.
This is an ideal feature for finding structure or locating fish near the
bottom.
Remember: If Bottom-Lock is the last function you selected, you
can use the ON-OFF button to switch Bottom-Lock on and off without
having to press SELECT first.
