The wide cone angles associated with low frequencies (40° for 50kHz) provide a large coverage area for finding fish. However, this also means that wide cone angles produce less bottom detail and resolution. The narrow cone angles associated with high frequencies (10° for 200kHz) provide better bottom resolution and crisper detail, but therefore cannot show a large coverage area for finding fish. Dual frequency mode combines the improved contour detail and depth readings of the 200kHz frequency with the wide coverage area of the 50kHz frequency.
To select a Frequency:1.Highlight the ‘Chart’ tab on the Setup Menu.
2.Highlight the ‘Frequency’ selection field and press ENTER.
3.Using the UP or DOWN Arrow, choose ‘200kHz,’ 50kHz’ or ‘Dual’ and press ENTER. The selected frequency will be displayed in the bottom

If a fish symbol is selected, the chart will display only the information related to that symbol.
To select a Fish Symbol:1.Highlight the ‘Chart’ tab on the Setup Menu.
