Screen Settings and Their Effects
When you right click the mouse while the mouse cursor is located on the
data display area, the “Full Screen Settings”, “Left Screen Settings” or
“Right Screen Settings” menu is displayed, depending on where you click
and whether the screen is in full or split mode.
Frequency
You can select 200 or 50 Khz.
The use of 200kHz will provide
you a more detailed display of
the sonar information and will
show smaller bait fish than can
be detected by using 50kHz.
The selection of 50kHz will
show data for a larger area
because the beam pattern of the
50Khz signal is much wider (45
degrees) than the beam pattern
of the 200 Khz transducer (11
degrees). 50 Khz is attenuated
less by water, however, and will
allow you to see deeper than you
can using 200Khz. A fish has to
be bigger to show up at a
frequency of 50khz. Often
professional fishermen will use
200 Khz on one side of the
display and simultaneously
display the results of the 50Khz
sonar signal on the other side of
the display.
