3-5-3 Single and Dual frequency fish finding

Sonar frequencies

The unit has dual frequency, 200kHz and

50kHz to detect various bottom conditions.

To select the sonar frequency in sonar

window:

1 Press , select Frequency.

2 Select frequency and press .

3 Press to exit.

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.

① High Frequency (200 kHz)

② Low Frequency (50 kHz)

3-5-4 Range

Range is the depth of water displayed on the

sonar window. The basic range may be

chosen in Auto or manual mode.

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.

To set the manual mode in the sonar

window:

1 Press , select Range.

2 Select a mode you want and press .

3 If you select the manual mode, press

or to change value of max

displayed depth.
