Chart Speed

Menu Item

Chart speed This adjusts the speed at which the information moves across the display. Use the < and > arrows of the Page Control Pad to change the chart speed. Making the bar longer increases the chart speed. If you move the bar all of the way to the left, the FishFinder will “freeze” and hold the current display. (The depth indicator will continue to update.)

If you are done with your setup changes, press the CLEAR button to go back to the normal display. To select the next menu item, press the V arrow of the Page Control Pad.

Frequency

Menu Item

“Frequency” is a measure of how fast the sound waves from the trans- ducer change or “vibrate.” This unit uses sound waves with two different frequencies— 50 kHz and 200 kHz. For an explanation on the uses of these two frequencies, see the section on “Choosing a Frequency.”

From the Chart Speed Menu Item, press the V arrow of the Page Control Pad. The next menu item will allow you to make the frequency setting. See Fig. 4-6.
