Vexilar FL-10 - Manual (Page 2)

GENERAL DESCRIPTION
The FL-10 is a
compact in-dash
mounted flasher
fish finder. Besides
indicating depth,
the unit also shows
changes in bottom
content and condi-
tions. It can also
d i s c r i m i n a t e
between large underwater targets, such as fish, and smaller
targets like baitfish and plankton.
The unit transmits bursts of high frequency pulses, which
are converted from electrical to mechanical energy by the
transducer. These "sound" pulses radiate from the
transducer downward and are reflected back up to the
transducer where the energy is converted back to electrical
signals. The FL-10 then processes these signals and displays
them.
The circular display is accomplished by attaching an LED
(Light Emitting Diode) to a wheel, which is then spun at a
high speed in the clockwise direction. This allows for an
extremely high speed update. The bottom, as well as other
targets, are displayed as red, orange, or green to indicate
strong, medium and weak signals respectively.
