USING THE PLATINUM ID 120

HOW SONAR WORKS
HOW SONAR WORKS
There are two main components to a Platinum ID installation: the sensor, which you will
install on the transom or inside the hull, and the Platinum ID unit. The sensor and
Platinum ID communicate by means of a cable, and are powered by your boat's 12-volt
DC battery.
The sensor and Platinum ID use the basic principles of sonar to reveal objects beneath
the water's surface.
The Platinum ID continuously sends electronic signals to the sensor, 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 sensor. As
the sensor receives these signals, it converts them back to electronic signals for display
on the Platinum ID screen.
