• TRANSDUCER
CONE ANGLES
The sound waves
from the transducer
spread
out
into the water
in a
cone
shaped
beam. This looks
much like the beam
from a
flashlight.
The
angle
between
the outside
edges
of the cone
is the cone
angle.
Eagle
offers
a choice of transducers
with either an
8 or 20
degree
cone
angle.
The transducer
supplied
with the
Ultra has a 20
degree
cone
angle.
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 theunderwater
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
water,
the 8
degree mostly
in salt
water. In a
deep
water environ-
ment,
(300
feet
-
fresh
water,
100 feet
-
salt
water)
the narrow cone
angle
is more
desirable. Since
the sound
energy
i'
concentrated
in a
smaller
area,
it
can
penetrate
to much
deeper depths.
