6. Using Bottom-Lock;
Factory setting: OFF
Bottom-Lock provides an up-close view like Zoom,
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 ENTER. A BL
indicator and the range of the display are 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
selected, you can use the ENTER button to switch Bottom-
Lock on and off without having to press SELECT first.

The LCR 3D lets you customize several aspects of its operation:
1. You can adjust the speed at which display updates. Matching this rate to the speed of your
boat provides the most accurate view of the underwater terrain.
2. The contrast level of the LCD display can be adjusted to optimize viewing from any angle.
3. The perspective of the on-screen view can be changed between left and right perspective.
