Humminbird LCR 8000D guide

You should also note that it is possible to have the sensitivity set too high such that reflection off of suspended matter or air bubbles will begin to black out the display.

In the manual mode the depth scale does not change automatically (See Paragraph 4 under Manual Mode). To once again activate the automatic mode, depress the Sensitivity Auto "On/Off" button.

If you get confused while in the manual mode, for example if you don't know where the bottom is, then press the Auto On/Off button to turn on the Automatic Mode. The LCR will find the bottom by selecting the proper sensitivity level and depth range. You can then go back to the manual mode if desired.

8.Zoom and Bottom Lock:

You will find the split screen zoom of the LCR to be a very valuable tool. The Zoom Range is controlled by the set and A or * buttons. Each time one of these buttons is depressed the zoom region will move one division. If the button is held down the region will continue to move as long as the button is held down.

The zoom region is indicated by a group of bars at the right side of the display. The size of this region may be selected as 15 feet, 30 feet, or 60 feet pressing the range size button. Each time this range size button is pressed the zoom range size increases until it is at the maximum, then the size goes back to the minimum. The following table shows the display resolution at each zoom range size:

Zoom Range Each Dot Equals 15 ft. 3 inches

30 ft. 6 inches

60 ft. 12 inches

What Zoom Does:

The zoom feature of the LCR will allow you to look at underwater readings in very fine detail. With the split screen capability you will be able to see both the full scale information and the up-close view at the same time on the same screen. And with the LCR's Total Screen Update you have the ability to zoom in on bottom, fish, and structure even after you have gone past an area.

How To Use Zoom:

First, position the zoom region next to the area that you want to expand by pressing the range set button and then the* or;* button. Next, by pressing the Zoom/Bottom Lock button the zoom will be activated. When the zoom is turned on, the display screen will automatically split to show the full depth scale information on the right side and the expanded view on the left side. Also, just above the word zoom on the left side of the display will be a group of small arrows indicating that zoom is on. (See Figure 18).
