AUTO frequency
If the frequency is set to AUTO, one of the two single frequencies (200 or 50 kHz) will be automatically selected, depending on the depth of the bottom. If the bottom is deeper than 350 feet (or 60 fathoms or 100 meters), the unit will use the 50kHz frequency. In shallower water, the unit will use the 200 kHz frequency.
MAN (Manual) frequency
You can also set the frequency manually. When you choose Frequency MAN, the cursor will jump down to the next line and wait for you to choose a frequency. Use the
< and > controls on the Page Control Pad to choose one of the following five frequency selections:
•200 kHz, single frequency – The unit will use only the narrow 200 kHz beam. If the fish symbols are enabled (in the System Setup Menu), they will appear solid.
•50 kHz, single frequency – The unit will use the wider 50 kHz beam. If the fish symbols are enabled (in the System Setup Menu), they will appear hollow.
•200 kHz, dual frequency – The presentation of the bottom image and fish targets is the same as with the single 200 kHz frequency. If fish symbols are turned on in the System Setup Menu, then they are displayed using the signal from the 200 kHz beam (solid symbols) as well as from the 50 kHz beam (hollow symbols).
•50 kHz dual frequency – The presentation of the bottom image and fish targets is the same as with the single 50 kHz frequency. If fish symbols are turned on in the System Setup Menu, then fish symbols are displayed using the signal from the 200 kHz beam (solid symbols) as well as from the 50kHz beam (hollow symbols).
•Split – The full image from both frequencies is shown at the same time. The 200 kHz display appears on the top half of the screen, and the 50 kHz display appears on the bottom half of the screen.
