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.
