Colorline lets you distinguish between strong and weak echoes. It 

"paints" a brighter color on targets that are stronger than a preset 

value. This allows you to tell the difference between a hard and soft 

bottom. For example, a soft, muddy or weedy bottom returns a weaker 

signal which is shown with a narrow, colored line (dark blue tinged 

with red or a little yellow.) Since fish are among the weakest echoes, 

they show up mostly as blue arches. A hard bottom or other relatively 

hard target returns a strong signal which causes a wider brightly col-

ored line (reddish yellow to bright yellow.) 
If you have two signals of equal size, one with red to yellow color and 

the other without, then the target with brighter color (yellow) is the 

stronger signal. This helps distinguish weeds from trees on the bottom, 

or fish from structure. 
Colorline is adjustable. Experiment with your unit to find the Color-

Line setting that's best for you.
