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 0 to 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 3 inches.

important thing is that you understand how to use Total Screen Update. Read on....

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 foot 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.

For example, if you go over some interesting structure or fish, you will be able to zoom in for a closer look without going back over the area. Simply activate the zoom and the in- formation that is stored in memory will be recalled and displayed on the left side of the screen. (See Figure 15.)

The operation of the zoom function is explained in a later section.

One of the standout characteristics of the LCR 8000 series is its large display, which typically measures 8 inches. The screen is designed to offer exceptional clarity and visibility, even in bright sunlight. With a resolution of 640 x 480 pixels, users can expect sharp images and detailed sonar readings. The LCR 8000D version takes this a step further with additional features such as a split-screen display, allowing users to monitor multiple functions simultaneously.

These models integrate advanced sonar technology, including dual-beam sonar capabilities. The LCR 8000 and 8000D can operate on both narrow and wide beam frequencies, enabling anglers to cover more water and get a more comprehensive view of underwater environments. The fish symbol identification feature provides an intuitive way for users to discern between fish and other objects, enhancing their chances of a successful catch.

Another notable feature is the AutoZoom capability, which automatically adjusts the viewing area to focus on the depth range where fish are most likely to be present. This real-time information helps users make quick decisions about where to cast their lines.

Additionally, the LCR 8000D offers an integrated temperature sensor, providing real-time water temperature readings that can be crucial for understanding fish behavior. The ability to record sonar logs is another innovative aspect, allowing users to review their fishing trips and analyze data for future outings.

Both models boast rugged construction suitable for various weather conditions, ensuring durability on the water. The user-friendly interface and straightforward controls make it accessible for both seasoned professionals and recreational anglers alike.

In conclusion, the Humminbird LCR 8000 and LCR 8000D represent a significant advancement in fish finding technology, combining powerful sonar capabilities, user-friendly design, and robust construction.
