Frequency Setting

“Frequency” is a measure of how fast the sound waves 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 frequen-

cies, see the section on “Choosing a Frequency.”

From the area of the display for the zoom settings, press the

arrow on

the Page control pad. The next menu item will allow you to make the

frequency setting. See Fig. 4-7.

Frequency Use the < and > arrows on the Page control pad to make

your choice.

You have four choices here:

• 200 kHz, single frequency – The unit will use the narrow 200 kHz

beam. The fish symbols will be solid.

• 50 kHz, single frequency – The unit will use the wider 50 kHz beam.

The fish symbols will be hollow.

• 200 kHz, dual frequency – The unit will use both frequencies, but the

image on the display will be generated using the information from the

narrow 200 kHz beam.

• 50 kHz dual frequency – The unit will use both frequencies, but the

image on the display will be generated using the information from the

wider 50 kHz beam.
