ASP
The
newest
technology
in noise
rejection systems
is Advanced
Signal
Processing
or ASP. This
system
constantly
evaluates the
incoming
sonar
signals, rejects
noise
signals,
and
displays
true echoes with a
minimum of interference. To our
knowledge,
this is the most advanced
noise
rejection system
available
in
sportfishing
sonar
today.
ASP
is
automatically
on when the Z-9500 is
first turned on. It's not
adjustable,
but
it can be turned on or
off.
Generally, you
will want to leave it
on.
