3. TRANSDUCER
WARNING
When plugging in or unplugging a transducer to the FF520 make sure power is turned Off.
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.
3.0 TRANSDUCER MOUNTING
3.0.0 Power Boats
Basically there are two hull types of powerboats: Planing and Displacement. In the following
pictures the boxes with lines are where the transducer should be installed.
Figure 3.0.0 - Planing (on the left) and Displacement (on the right)
The planing hull allows the boat to rise quickly out of the water, allowing the boat to travel
at higher speeds.
The displacement hull does not ride up on top of the water; rather it pushes through the water.
3.0.1 Sailboats
Mount the transducer in the first third part of the boat, just forward of or the side of the keel.

3.0.2 Transducer Types
Since there are many different shapes and sizes of hulls, STANDARD HORIZON offers a
range of Depth transducers to fit the vessels requirements.
