Lowrance electronic X-3 CD Player User Manual


 
TRANSDUCERS AND CONE ANGLE
The sound waves from
the transducr
go
down ihto the water in a cone
shaped beam,
much like the beam frOm a
flashlight
The
angle
betWeen
the
outside
edges
of
the cone is called the cone
angle.
Lowrance offers a choice of transducers with either an 8 or 20
degree
cone
angle
that will
interchange
with
any!
of the 192 kHz sonar
products.
In other
words,
any
Lowrance sonar instrument can be used with
any
Lowrance transducer of
the same
frequency
without
retuning
of
any kind,
and no loss of
performance.
However,
the use of
any
other manufactur-
ers' transducer will result in a loss of
performance.
Generally,
wide cone
angle
transducers
(20 degrees)
are
ideally
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 that's
about six feet across. The 8
degree
transducer covers
only
about a two foot circle.
