Vexilar FL-8SLT - Manual (Page 2)

GENERAL DESCRIPTION
The FL-8SLT is a compact
and lightweight depth
sounder designed for serious
anglers. Besides indicating
depth, the unit also shows
changes in bottom content and
conditions. It can also dis-
criminate between large
underwater targets, such as
fish, and smaller targets such
as bait fish 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-8SLT 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, can be displayed as red, orange, or
green to indicate strong, medium and weak signals respectively. The FL-
8SLT also has patented Interference Rejection (IR) Technology. This lets
the user "filter out" unwanted interference from another nearby depth
sounder. With two models available, deep and shallow, and a wide vari-
ety of accessories to choose from, the Vexilar FL-8SLT is second to none.
