SECOND ECHO
-
Another echo that
registers
at
roughly
twice the
depth
of a
target
echo. This is caused
by
the sound waves
reflecting
off
the
bottom, striking
the surface of the
water,
travelling
to the bottom
again,
and
returning
to the surface.
SECOND FUNCTION KEY
-
A button that converts the functions of the
primary keys
to other functions.
SENSITIVITY
-
The
ability
of a sonar unit's receiver to
display targets.
Increasing
the
sensitivity
allows weaker
targets
to be
displayed.
Also
called
"gain".
SCROLL SPEED
-
See CHART SPEED.
SHOOT-ThROUGH-HULL
-
A transducer installation
which allows the
sonar
signals
to
pass through
a
fiberglass
hull without
cuffing
a hole in
the hull.
SUPPRESSION
-
A method used in some sonar
units to
help
eliminate
interference or noise.
SURFACE CLARITY
CONTROL
-
Reduces or eliminates undesirable
signals displayed
near the water's surface. Also called "SCC".
THERMOCLINE
-
A
layer
of water caused
by
the
meeting
of warm and
cool
layers
of water. The thermocline
provides
the
temperature
most
fish
prefer.
TRANSDUCER
-
The element of a sonar
system
that
converts the
electrical
energy
from the transmitter into ultrasonic sound waves.
When a return echo strikes the
transducer,
it
converts the sound waves
into electrical
energy
which is received and
displayed by
the sonar unit.
TRANSOM MOUNT
-
A method of
mounting
transducers or other
sensors on the transom of the boat.
UPPER/LOWER LIMIT
-
These are the
range
limits
displayed
on the
sonar screen or
paper.
The
upper
limit is shown at the
top
of the
display,
while the lower limit is
at the bottom. For
example,
a 20 to 30
foot
range
has 20 feet as the
upper
limit and 30 feet as the lower limit.
