the bottom echo to categorize bottom hard-
ness in one of four types (rocks, gravel, sand, 
mud) and shows the results in a colorful 
graphic display. A transducer or triducer that 
supports the bottom discrimination display is 
required.

There are two bottom discrimination displays: 
graphic and probability. 

Graphic display: The most probable material 
on the bottom (mud, sand, gravel, rock) is in-
dicated graphically. 

Probability display: The most probable bot-
tom material is indicated in proportion.
