Vexilar LC-10 - Manual (Page 2)

GENERAL DESCRIPTION
The Boundary Waters model LC-10 is a compact and
light-weight liquid crystal depth sounder. It indicates depth,
shows changes in bottom content, and conditions. It can
also discriminate 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 trans-
ducer downward and are reflected back up to the trans-
ducer where the energy is converted back to electrical sig-
nals. The LC-10 then processes these signals and displays
them.
The graphic display is accomplished by activating indi-
vidual or groups of pixels, or dots, on the LCD. The first
vertical column of pixels, on the right edge of the display,
shows the most current information. This column is then
moved to the next place, to
the left, as soon as a new col-
umn is ready. This process is
repeated continually to make
up the graphic display. Thus
what you see on the display
is a brief history of what the
boat just went over. The LC-
10 displays the depth as an
easy to read number in the
lower corner of the display.
