EQ42/50/52 Principles of operation Chapter 8 8.1 Parts of an echosounder An echosounder is composed of a display screen, processor, and receiver/ transmitter unit which in the case of the EQXX, are housed in one unit. Connected to this unit by a shielded cable is the transducer which is mounted horizontally on the bottom of the hull or on the transom.
Shielded cables connect the transducer with the echosounder. 8.2 How the EQ42/50/52 MKII works When the EQXX is turned on, the processor begins to send electrical pulses to the transducer.
EQ42/50/52 Principles of operation Chapter 8 8.2.1 Transducer beamwidth The transducer mounted to the hull of your vessel serves as both a “speaker” when transmitting, and as a “microphone” when the echosounder is receiving. Similar to the way a flashlight focuses light, most of the sound from your transducer is focused downwards with a smaller amount going out to the sides.
EQ42/50/52 Principles of operation Chapter 8 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 half what it was in the center. The distance moved is the “beamwidth”.

The units with the same model numbers are identical in size e.g. DS42 and EQ42, so the same installation guides can be used when performing the installation. When choosing a dual station, the unit does not have to match the main unit in size, as all the mentioned units are compatible.

EQ42/50/52 Installation and service Chapter 9 It is of profound importance for good performance of the EQXX that the water flowing over the transducer be free of bubbles and aeration. If the transducer face is clean but the performance degrades with increasing vessel speed, then aeration of the water flowing under the transducer may be the cause of the poor performance.
If the EQXX requires servicing or repair, call your authorized SIMRAD dealer, but first check section 9.10 Troubleshooting. Spare parts – fuses may be bought from a chandlery or a marine supply store. If you require a SIMRAD part, please contact your authorized dealer.

EQ42/50/52 Glossary of terms Appendix A Ping to ping filter – can be set to either on or off. With the filter “off”, then each received echo will be reflected on the screen. Whereas with the filter “ON”, the system will compare every two echoes received and only reflect on the screen what is received from both echoes, which will give a more uncluttered and precise presentation.

EQ42/50/52 Glossary of terms Appendix A Transducer – the transducer serves 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 EQXX transmits a signal), and they also generate a voltage when they encounter sound waves (as when the EQXX receives an echo).
