Sonar
Colorline
Distinguishes strong sonar echoes from
weak sonar echoes. That makes it easier
for you to distinguish sh or structure from the
bottom.
A hard return will be shown as a wide, bright
yellow line, whereas a soft return will be a
narrow reddish-blue line.
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.
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.
Split
Adjusts the conguration of sonar page display using one of four options: No Split,
Zoom, Bottom Lock and Flasher.
