Humminbird LCR 3D - Manual (Page 18)

WHAT YOU SEE ON-SCREEN
The 3-dimensional image you see reflects the way 3-dimensional sonar works. The sonar
projects a narrow beam front-to-rear, and a broad beam leftto-right. The LCR 3D interprets the
sonar returns to assemble the image displayed on the screen. As you view this image, your boat
is at the center of the leading edge, traveling toward the right. What's displayed on the screen is
what's immediately behind you. The image is updated constantly as you travel though the water.
There are three different ways to view the sonar information, each is accessed by
pressing the VIEW button.
The 3D view is what you see when you first power the unit up, and provides a detailed
three dimensional picture of the terrain beneath your boat. This view can be oriented in two
different ways, left perspective, or right perspective to suit your individual preference. Adjusting
the perspective is done through the select system - see Custom Program in Section 5 for detailed
instructions.
Left perspective orients the three dimensional picture so that objects to the right of your
boat are shown on the right of the screen, and objects to the left of your boat are shown on the
left side of your screen.
