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 CLC-200 is in the AUTO mode, it
automatically senses the bottoms depth and tries to keep
the best view at all times. Although the display may not
show it, the CLC-200 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 can show
erroneous information. The graphic display will become
overly cluttered and the digital numbers on the display can
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
depth finder.
It often helps to turn off the automatic range and gain
features and manually set the range to the shallowest
setting and the gain to a low level. 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.
