How The Lcr-100 Works; The Humminbird Advantage - Humminbird LCR 100 Operation Manual

HOW THE LCR-100 WORKS

There are two main components to your LCR 100 installation: The transducer, which was
installed beneath your boat, and the LCR 100 unit, mounted either in-dash or on a gimbal
bracket. The transducer and LCR 100 communicate by means of a cable, and are powered by
your boat's 12-volt DC battery.
The transducer and LCR 100 use the basic principles of sonar to reveal objects beneath the
water's surface. The LCR 100 continuously sends electronic signals to the transducer, which
converts them to ultrasonic signals that it aims toward the bottom. Each signal travels downward
until it strikes an object or the bottom, then immediately echoes back to the transducer. As the
transducer receives these signals, it converts them back to electronic signals for display on the
LCR 100 screen.
The LCR 100 uses the returned signals to display a detailed underwater image, and constantly
updates the display as you travel across the water. The display informs you of the current depth
and reveals individual fish, schools of fish, their location, and bottom details.
Easy-to-use controls on the LCR 100 allow you to set the depth range, adjust display speed and
sensitivity, enable a fish alarm and bottom alarm, and display a "zoom" window of still more
detailed information.

THE HUMMINBIRD ADVANTAGE

The LCR 100 incorporates the best of available technologies, and offers advantages you
won't find in other depth sounders.
The liquid crystal display (LCD) offers sharp viewing even in bright, direct sunlight, and is
continuously lit for nighttime operation. Advanced LCD "super-twist" technology built into the LCR
100 offers a wider viewing angle and higher contrast than ordinary LCD screens.
