Raymarine L470 instruction manual Operating Instructions, Zoom magnification

Many of the items presented by the Zoom Mode are the same as those on the FishFinder Page. There are a few additional items:

Zoom magnification

This indicates the amount of “zoom” or magnification. You always set the amount of zoom manually. While the Zoom screen is visible, press SETUP. This will bring you to the Zoom Menu, shown in Fig. 4-10. You can choose an x2 view (double the normal display size), x4, x6 or x8. See Section 4 for details. You must also select the area or “window” of the water you want to zoom. See the next item.

Zoom area When you turn on the zoom feature, it can only enlarge a part of the FishFinder Page. You must decide which part you want to enlarge. As we said, the right side of the “split” display shows the normal FishFinder Page. The vertical line at the right edge of this display shows the area or “window” of the water being enlarged.

When the FishFinder is set for Auto Zoom, it will choose the zoom area automatically. The unit always chooses an area of the water which includes the bottom. The unit then moves this area up or down to keep the bottom in the picture. The Auto Zoom feature is great for bottom fishing.

You may also set the zoom area manually. While the Zoom screen is visible, press SETUP. This will bring you to the Zoom Menu, shown in Fig. 4-10. You can then select Manual Zoom. See Section 4 for details. Once you are back to the zoom display, you can move the zoom area up or down (using the < and V arrows of the Page Control Pad) to select the area you want to be enlarged.

The Zoom image can also be presented using the whole display. See Section 4 for details.

If you want to exit from the Zoom Mode, press the Zoom button again while the Zoom image is visible. For a moment the display will say, “Exiting Zoom Mode,” then the unit will return to the FishFinder Page.
