What is Total Screen Update?
Total screen update is a unique feature of Humminbird LCRs. It will allow you, when changing depth scales, to totally change or update the screen to the new depth scale. It will allow you to zoom in and look at information in much finer detail even after you’ve already gone over the area.
How Does Total Screen Update Work?
Inside the LCR are memory devices which can store information. Automatically, while you're operating the LCR, the computer is putting information into the LCR'S memory.
All this information is being put into memory in much smaller increments (pieces) than is being displayed on the normal full depth scales. For example, on the 0to 60 foot scale each dot is equal to one foot of depth, but the computer is putting information into memory such that each dot equals 2½ inches.

How To Use Total Screen Update
This is the easiest part. Since the LCR’s computer is doing all the work, you will find the LCR Total Screen Update very easy to use.
There are two ways that you will use Total Screen Update:
1.When changing a depth scale the LCR’s computer will automatically change or update the entire screen to the new depth scale. This Total Screen Update feature works when changing to deeper or shallower scales. For example, suppose you are in the 0 to 120 foot scale but the bottom depth changes quickly to 20 feet. When the depth range is changed to the 0 to 30 toot scale, the entire screen will look just as if you had gone over the area on the 0 to 30 foot scale.
2.The second way that you will use Total Screen Update is in operating the LCR's Zoom or Bottom Lock. Since the computer has stored in memory information in very small increments, you will be able to recall this information from memory to get an expanded view of areas which you have already passed over.
