since often many species of game fish like to suspend in, just above, or just below the
thermoclines.
White Line
The White Line shows the difference between hard, soft bottoms and even distinguish-
es between fishes and structures located near the bottom. In this way it is easier to tell
the difference between a hard and soft bottom and even to distinguish fishes and
structures located nearby the bottom.
Surface Clutter
Appears like noise at the top of the screen extending many feet below the surface. It’s
caused by many things, including air bubbles, bait fish, plankton and algae.
Structures
Generally, the term “structure” is used to identify objects like wrecks and weeds rising
from the bottom.
Bottom Echo Profile
Bottom profile recorded by the Fish Finder. When the echo sounder is set in Auto
Range mode, the bottom is kept in the lower half in the display.
