Humminbird 120 Fish Finder User Manual


 
USING THE PLATINUM ID 120
HOW SONAR WORKS
The Platinum ID 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, bottom
details as well as bottom hardness.
An easy-to-use control also lets you enable a depth alarm for an audible alert when the
boat is in shallow waters.
The Platinum ID incorporates the best of available technologies, and offers advantages
you won’t find in other depth sounders.
The liquid crystal display offers sharp viewing even in bright, direct sunlight, and is
backlit for nighttime operation. Advanced LCD “super-twist” technology built into the
Platinum ID offers a wider viewing angle and higher contrast than ordinary LCD
screens.
(You will notice that the display can be seen better at certain angles. The All-in-One
Mounting System lets you easily adjust the viewing angle for optimum viewing. Note
also that some polarized glasses can affect your view by causing a rainbow or prism to
appear; if so, tilt the unit slightly.)
Though it includes sophisticated electronics, the Platinum ID is tough enough to take
the pounding punishment of rough seas or a race across the lake. Completely
waterproof - even saltwater-proof your Platinum ID will provide you with years of
thoroughly reliable operation.
