Range
Used to select the section of the water column —
from surface to bottom — shown on the display.
When there is a portion of the water column you
want to focus on, select a range from the Depth
Range menu that includes the desired area.
The values on the Range menu determine the depth
shown on the display. If you selected 20m from the
range menu the unit will display 0-20m of the water
column, regardless of the water depth. There are 21
depth ranges, including automatic and custom settings. The automatic setting will
set the range from the water surface to water depth.
To select a depth range:
Press the 1. Range softkey. The Range menu will appear.
Use the keypad to select the desired depth. Press the softkey again 2.
to return to normal operation.
Frequency
This unit supports three transducer frequencies; two of which are supported by your
transducer. 200 kHz has the highest sensitivity and best target discrimination in
shallower water; 83 kHz offers a wider cone angle for greater water coverage and
50 kHz provides the best depth penetration. You can view both available frequencies
at the same time by setting up a sonar split screen.
To make adjustments, press the
Frequency softkey to toggle through transducer
frequencies.
Split
