TRANSDUCERS
AND CONE ANGLES
The sound waves from
the transducer
spread
out into the
water in
a cone
shaped
beam. This looks
much likethe beam
from
aflashlight.
The
angle
between
the outside
edges
of the cone
is the cone
angle.
Eagle
offers a choice of
transducers with either
an & or
20
degree
coneangle.
Thesewill
interchangewith anyofthe
192 kHz
sonarproducts.
In otherwords,
use
any
Eagle
sonar
instrumentwith
any Eagle
transducer
of the same
frequency
with no loss
of
performance.
However,
the use of
any
other
manufacturers' transducer
will result
In a loss of
performance.
Typically,
wide cone
angle
transducers
(20
degrees)
are ideal
for
operating
In shallow
to medium
water
depths.
The 20
degree
cone
angle
allows
you
to see
more of the underwater
world. In 15 feet
of water
the 20
degree
cone covers
an area about
six feet across.
The 8
degree
transducer
covers
only
about a two foot
circle.
LOWER LIMIT
To
changethe
lower
limit,first
make certain theword
"AUTO" is off
at
the
top
of the screen.
This indicates that
the automatic
mode Is off.
(Note:
This also disables
the automatic
sensitivity function.)
If the auto-
matic
mode is
on,
press
the AUTO
key
once to disable
it.
Next, press
one
of the
arrow
keys
In the RANGE
section.until
the desired lower
limit
appears.
The
display
will
immediately change
to
the new
depth
range
and
display
the
new lower limit at the bottom
of the screen.
NOTE:
The maximum lower limit
the Z-7200 can
display
is 1000 feet.
However,
the
actual
depth
that
it
can
reach Is
dependent
on water
and
bottom
conditions, plus
the
quality
of the transducer
installation.
ZOOM
[;;M]
Often it's
desirable to
expand
or
"ZOOM" a section
of the
display
to show more detail.
You can do this
on the Z-7200
by
using
the ZOOM
feature. If the unit is
in the manual
mode, press
the ZOOM
key
to
double
the size of the
targets.
For
example,
if the
range
is 0-60
feet,
pressing
the
ZOOM
key changes
the
range
to 30-60
feet. This 30-60
range
is called a
"window". To
change
the
windowsize,
press
the
up
ordown arrows
in the
ZOOM: 30-60 FEET
