3-3-2 Single or dual frequency fish fishing
Sonar frequencies
The unit has dual frequency, 200kHz and
50kHz to detect various bottom conditions.
1 Press
, select Frequency.
2 Select one frequency
High frequency (200kHz )
The higher ultrasonic signal, the better is
the resolution. For this reason the 200 kHz
frequency is ideal for detailed observation
of fish schools.
Low frequency (50kHz)
The lower frequency signal is, the wider is
the detection area. Therefore, the 50kHz
frequency is useful for general detection
and judging bottom condition.
Mixed frequencies (200kHz / 50kHz)
The Mixed frequency combines the 200
kHz and the 50 kHz in the Sonar window.
The 50kHz picture appears on the left and
the 200kHz picture on the right.
The display is useful for comparing the
same picture with two different
frequencies.

3-3-3 Range
Range is the depth of water displayed on
the sonar window. The basic range may be
chosen in Auto or manual mode.
To set range
1 Press
and select Sonar
2 Select depth and select a mode (manual
or auto).
Depth range can be adjusted by knob.
Or by pressing
and after pressing
F3 and F2 twice.
Auto: When the mode is set to Auto, the
unit adjusts the depth automatically for the
best performance. This option is
recommended for normal operation.
Manual: When the mode is set to Manual,
the unit only displays the depth of water at
a given range. That means the sea bottom
might not be displayed in the sonar
window or it might display half of display in
white because range is more important
than sea bottom depth. As shown in below
images.
