Greyscale 

The 2100 display uses a grey checkered pattern to display the strongest 
signals, which are usually from a hard bottom (see Figure 2).   Weaker 

signals above the bottom are displayed as black.  This allows you to separate 
the bottom from weeds and to differentiate a hard bottom from a soft, 

muddy one.  A soft bottom typically gives a thinner bottom image that is 
mostly black.   A hard bottom is displayed as a thin, black line over a much 

thicker area of checkered grey.  Light weed cover above the bottom will 
give a thicker, sketchy black area above the checkered grey. 

 

Note: 

The size of the object does not always correlate directly with the 

strength of the signal.    

Fish 

To view the natural echoes from fish and other objects in the water, turn 
the fish alarm symbols

 

off (see page 8).  Many fishermen have heard that an 

arch is a good way of determining fish, but other objects you troll across 
may also produce arches. 
A better way of determining fish is to watch for subtle patterns on the 
graph.  Solid horizontal lines across the screen are often fish hovering 

under the transducer.  These lines may go up and down suggesting some 
movement if they are fish.  Generally, thicker marks come from larger fish. 

Clouds of pixels are often schooling baitfish.  Groups of diagonal lines are 
usually bubbles rising steadily up from the bottom.  As you get more 

familiar with the 2100 and the water that you fish in, you will pick out many 
other patterns as well. 

M

AINTENANCE

 

Your 2100 should work reliably for many years, however, there are a few 

things you may want to consider and check periodically: 

• 

When cleaning the acrylic display lens, do not use ammonia or alcohol-

based cleaners. 

• 

If possible, periodically clean the surface of the transducer with soap 

and water to remove any oil film.  Oil and dirt on the transducer will 
reduce the sensitivity or may completely inhibit transducer operation. 

• 

Consider using commonly available corrosion inhibitors on the back-

panel connectors in harsh environments.
