White Line
The White Line shows the difference between hard, soft bottoms and even
distinguishes 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. For example,
a soft, muddy or weedy bottom returns a weaker echo that is shown with a
narrow white line while a hard bottom returns a strong echo that causes a
wide white bottom line.
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 it is automatically kept in the lower half of the screen.
Other Elements
Large anchoring cables are returned by the echo sounder as very long and narrow
arcs on the screen.
