User Manual
cone strikes the fish, causing a display pixel to be turned on. As the boat
passes over the fish, the distance to the fish decreases turning each pixel
on at a shallower depth on the display. When the boat is directly over the
fish, the first half of the arch is formed and since the fish is closer to the
boat, the signal is stronger and the arch is thicker. As the boat moves
away from the fish, the distance increases and the pixels appear at pro-
gressively deeper depths forming the remaining half of the arch.
Thermoclines
Are the zones where two layers of different water temperatures meet.
The greater the temperature differential, the thicker the thermocline is
shown on the screen. Thermoclines are represented as horizontal stripes
of noise. They are very important for fishing 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
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.
