How Your 2100 Works

The 2100 uses active SONAR, short for Sound Navigation and Ranging, to
locate and identify objects in the water. The transducer sends out short

bursts of ultrasonic sound waves into the water and then listens for echoes
to come back from objects and the bottom. The further away the object or

bottom is, the longer it takes the echo to return.
These ultrasonic waves “illuminate” the water, forming a beam that is

be used for finding fish as well. You can calculate the approximate
diameter of the main beam on the bottom as the depth divided by six.

Reading the Graph

The bottom graph is created by drawing all of the echoes from a single
burst in a vertical column on the display, with the echoes from deepest

objects drawn lowest on the display. After all the echoes from the burst are
drawn, the graph is shifted to the left and the process is repeated (see
