behind the transom. If your transducer is poorly mounted,
the unit will lose the bottom at a certain boat speed. This
is due to all of the air bubbles in the turbulent water.
Readjustment of the transducer mounting should solve this
problem.

SHALLOW WATER OPERATION

When the LC-10 is in the AUTO mode, it automatical-

ly senses the bottoms depth and tries to keep the best view
at all times. Although the display may not show it, the LC-
10 is monitoring basic sonar signals such as the bottoms
second echo and various target's signal strengths. This way
it can maintain the optimum gain level, automatically, for
you.

In very shallow water (less than 3 feet) the unit can get

"over-welmed". In this condition the unit will show erro-
neous information. The graphic display will become most-
ly black and the digital numbers on the display will read
depths that are much deeper than reality. These depths are
actually multiple echoes of the real bottom. It is important
to use caution when navigating in shallow waters. Use
common sense. Don't rely solely on your depthfinder.

It often helps to turn off the AUTO feature and manu-

ally change the range to the 5 or 10 foot range. This tells
the LC-10 that you are in shallow water and it will adjust
the gain appropriately. If the digital depth reading doesn't
seem right, it is probably a multiple of the correct depth.
Use the graphic display as a better reference.
