Colorline
Fish ID

making it easier to distinguish sh or structure
from the bottom.
A hard return will be shown as a wide, bright
yellow area, whereas a soft return will be a narrow
reddish-blue area.
Range

on the screen.
The unit will not lock onto the

to lter out the eects noise (boat
pumps, water conditions, engine
ignition systems, etc.) has on your
display.
