1.16 Bottom Discrimi-
nation Display
The bottom discrimination display analyzes
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.
