The formation of bubbles, which may negatively impact a transducer’s readings by reducing its ability to put energy into the water.
The rise of the bottom of a vessel above a horizontal line at the center of the vessel; that is, the slope of the hull away from the horizontal.
An instrument that uses sound waves to measure the depth of a body of water or an object (such as a school of fish) below the water’s surface.
A block used to create a horizontal surface for mounting a
The device mounted through the hull to send and receive ultrasonic beams that determine seabed conditions and locate fish. Essentially, a transducer is an energy converter, which changes electricity to sound (send) and sound to electricity (receive).
