6. TRANSDUCER
The transducer is a device that transmits and receives sound waves into the water. The
active component inside the transducer is commonly referred to as an element but actually
is a piezoelectric ceramic material.
6.0 TRANSDUCER MOUNTING
6.0.0 Power Boats
Basically there are 2 hull types of powerboats Planing and Displacement. In the pictures
shown below the boxes with lines are where the transducer should be installed.
Figure 6.0.0 - Planing
The planing hull allows the boat to rise quickly out of the water, allowing the boat to travel
at higher speeds.
Figure 6.0.0a - Displacement
The displacement hull does not ride up on top of the water; rather it pushes through the
water.
6.0.1 Sailboats
Most sailboats that use digital depth sounders/transducers are displacement hulls. There
are two basic hull types of sailboats:
