Connected to this unit by shielded cables are the transducer(s) which are mounted horizontally on the bottom of the hull.

950-70017001/Iss 1.2 Page 3.4 EQ-55 Operators Manual Principles of Operation of an Echo Sounder 3.1.4 Transducer(s) A transducer is composed of a number of elements embedded in a housing which has been reinforced with polyester or fiberglass. The transducer is attached horizontally to the bottom of the hull. It is essential that the transducer be mounted properly as echo transmissions are radiated at right angles from the transducer face. Shielded cables connect the transducer with the echo sounder. 3.

EQ-55 Operators Manual Principles of Operation of an Echo Sounder 950-70017001/Iss 1.2 Page 3.5 The sound waves move through the water until they encounter a change in density, such as a fish or the bottom. This causes the sound waves to " echo " back up through the water. When the reflected sound waves (echoes) hit the transducer the ceramic disks vibrate at the same frequency. This voltage goes back up through the cables to the receiver.

950-70017001/Iss 1.2 Page 3.6 Figure 3.3 EQ-55 Operators Manual Principles of Operation of an Echo Sounder A representation of a transducer beamwidth The center of the sound beam is the most intense, then as you move out towards the sides of the sound beam there is a point where the intensity of the sound is 1/2 what it was in the center. The distance moved is the "beamwidth".

As a vessel rolls, the sound beam swings back and forth, and can occasionally be pointing too far to port or starboard to see a small target clearly. The choice of transducer beamwidth is always a compromise. See 3.6 Figure 3.

950-70017001/Iss 1.2 Page 3.8 EQ-55 Operators Manual Principles of Operation of an Echo Sounder 3.4 CHOICE OF FREQUENCY Your EQ-55 has two built-in frequencies. The lower frequency is most useful for work in deep water. The high frequency will not usually be able to see as deep as the lower frequency, but the higher frequency is best for seeing small targets and greater detail. For example, looking for small bait fish is best done with the high frequency.

The power input connector contains two fuses each rated at 2 amperes. To remove or replace the fuses, pry the cover off the connector using a small screwdriver. The AC voltage selection is done manually.

It depends very much on the vessel’s construction. However, there are some important guide lines. 4.3.2 Go Deep The upper water layers of the sea contain myriads of small air bubbles created by the breaking waves.

950-70017001/Iss 1.2 Page 4.12 EQ-55 Operators Manual Installation Instructions for the EQ-55 mixed into the boundary layer. The Boundary layer is thin underneath the forward part of the vessel, and increases in thickness as it moves aftwards. If the sides of the hull are steep, some of the air bubbles in the boundary layer may escape to the sea surface along the vessel sides.

EQ-55 Operators Manual Installation Instructions for the EQ-55 950-70017001/Iss 1.2 Page 4.13 Bow thrusters are awful machines. When they are in operation, the noise and cavitation bubbles make the echo sounder useless, almost no matter where the transducer is installed. And when not in operation, the tunnel creates turbulence, and if the vessel is pitching, the tunnel may be filled with air or aerated water in the upper position and release this in the lower position.

EQ-55 Operators Manual Appendix B Glossary 950-7001001/Iss 1.2 Page B.7 TRANSDUCER The transducers serve as the acoustic "loudspeaker" and "microphone" to send and receive the signals through the water. Transducers are most often made from ceramic elements carefully built into a robust housing. The ceramic elements change shape when a voltage is placed across them (when the EQ 55 transmits a signal), and they also generate a voltage when they encounter sound waves (as when the EQ 55 is receiving an echo).
