Combining Displays

The FishFinder L470 unit can combine displays in many different ways. This allows you to make maximum use of the display area, and choose only the information you really want. Here are some of the ways the images can be combined.

Dual-frequency split screen –

If you choose this setup, the unit produces a horizontal split across the screen. The image on the upper half of the display is produced by the 200 kHz transducer element, and the image on the lower half is produced by the 50 kHz transducer element.

Notice that you can combine the dual frequency feature with any of the normal displays— the FishFinder Page by itself, or with the Zoom, A- Scope, or Bottom Lock Modes. In Fig. 4-19, the A-Scope Mode has been combined with the dual-frequency feature.

Window Page –

If you begin at the standard FishFinder Page and press the > control, the unit will present a Window Page. Figure 3-7 shows an example. Notice that there is a vertical split down the center of the screen. The Digital information takes over the left half of the display. The other half is occupied by one of the normal displays— the FishFinder Page by itself, or with the Zoom, A-Scope or Bottom Lock Mode. Notice that, if you have specified a “split” image for either the Zoom or Bottom Lock Mode, the image on the right side will be divided vertically again.
