Eagle
offers a choice of
transducers
with either an 8 or 20
degree
cone
angle
that will
Interchange
with
any
of
the 192 kHz sonar
producth.
In other
words,
any Eagle
sonar instrument
can be used
with
any Eagle
transducer of the
same
frequency
with no loss of
performance.
Howevet
the use of
any
olher
manufacturers'
transducer will result in a
loss of
performance.
Generally,
wide
cone
angle
transducers
(20 degrees)
are
ideafly
suited
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.
The
20
degree transducer is almost
always
the best
to use in fresh
wate
while the 8
degree
transducer
is used
mostlyin
salt water. In a
deep
water
environment, (300 feet—fresh
water, 100 feet—salt
water)
the
narrow
cone
angie
is more
desireable because it
can
penetrate
to much
deeper
depths
since
the sound
energy
is
concentrated in a smaller
area.
________
Both 8
degree
and 20
degree
transducers
give
accurate
bottom
readings,
even
though
the
bottom
signal
is
much wider on the 20
degree
model
because
you
are
seeing
more of the
bottom. Remembet
the
shallow
edge
of the
signal
showa
you
the true
depth.
The rest of the
signal
tells
you
whether
you
are
over
rocks, mud,
etc.
Transducers on
saltwater boats need to
be
painted
with a
thin coat of
anti-foulant
paint
to
prevent
organisms
from
growing.
If
unchecked,
barnacles
and other
marine
growth
will
cause a decrease
in the
transducer's
sensitivity.
Do not use a
metal based
antifoulant
paint
as it
will
decrease the
transducer's
senstivity.
There are
special
anti-foulant
paints
specifically
designed
for
transducers.
They're readily
available at
most marine
dealers.
SIGNAL
INTERPRETATION
Because
your
Z-6100
is both
extremely
sensitive
and
powerful,
it
can
give you
an
accurate
picture
of
the kind of bottom
over which
your
boat
is
passing.
A
bottom of firm
sand,
gravel, shell,
or hard
clay
returns a
fairly
wide
signal.
If the
automatic
sensitivity
is turned
off,
and
the
signal
narrows
down,
then it
means that
you
have moved
over a mud
bottom
because mud
absorbs the
sound wave and
returns a weak
signal.
Turn
up
the
sensitivity.
If
you
have the
automatic
senstivity
turned
on,
watch the
sensitivity
bar. As the
boat
passes
over
the mud
bottom,
the Z-6100
will
automatically
increase
the
sensitivity
to maintain a
good
bottom
signal.
The
sensitivity
bar
will
help you
in
determining
if the bottom is
soft or
hard. If it
increases
while in the
same
depth
of
wat&,
then the boat
has
moved over a soft
bottom, if it
decreases,
then it
is over a
hard bottom. Of
course,
as
the water
depth
increases or
decreases,
the
sensitivity
will
also
change.

CHART The chart
speed
is
,v
controlled
by
the CHART
group
of
keys.
The Z-6100 has 32
chart
speeds, ranging
from
Very
slow to
FAST.
Pressing
the
FAST
key speeds up
the chart
speed.
The slow
key
reduces it.
The chart

again by
pressing
both arrow
keys
at the

,__._—RANGE
The
rengb keys
allow
you
to select
different
depth
ranges
by pressing
the
up

down arrow. The available
ranges
ere:

AUTO
The AUTO
key
switches the Z-6100 in or out
of
the automatic mode,
when the
Z-6100 is
first turned
on,
it
automatically adjusts
the
sensitivity
and

and the word
"AUTO" will be
displayed
near the

By
pressing
the
AUTO
key, you
can take
control of the
Z-6100, making manuel
