Raymarine L470 instruction manual Setup Instructions, Changing the Chart Speed Setting

Chart Speed Setting

Most of the displays on the FishFinder show a record of the signals the unit has received. The new information appears at the right (or top) edge of the display. The older information moves toward the left (or bottom) of the display. The “chart speed” adjustment sets the speed at which the display moves. (Notice that the scrolling speed of the display is not related to the speed of the boat over the bottom. The speed of the display is controlled only by the chart speed setting.)

Changing the

Chart Speed

Setting

Figure 4-4 shows how the chart speed setting affects the display. In both cases, the unit is showing the same section of the bottom. Using a faster chart speed, the display has more space on the display to show this section, so it can include more detail. Using a slower chart speed, this same information is displayed in a smaller horizontal space.

A faster chart speed setting shows more detail on the bottom. You will probably want to use a faster setting when you are looking for fish.

A slower chart speed setting shows a longer record of the bottom you pass over. Any fish detected will stay on the display longer.

From the display for the sensitivity setting, press the V arrow of the Page Control Pad. The next menu item will allow you to set the chart speed. See Fig. 4-5. The chart speed adjustment affects both the normal downlooking display and the Sidelooker display.
