GENERAL DESCRIPTION
The LC-8 is a compact and lightweight 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 con-
verted 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 LC-8 then processes these signals and
displays them.
The graphic display is
accomplished by activating
individual or groups of pix-
els, or dots, on the LCD. The
first vertical column of pixels,
on the right edge of the dis-
play, shows the most current
information. This column is
then moved to the next place,
to the left, as soon as a new
column is ready. This process
is repeated continually to
make up the graphic display.
Thus what you see on the dis-
play is a brief history of what
the boat just went over. The LC-8 displays the depth as an easy to
read number in the lower corner of the display
The LC-8 has many functions that can be controlled by the user.
Once you set the unit the way you want it, all of your settings are
saved in memory, so that when the unit is used again no reprogram-
ming is needed.
