EQ42/50/52 Introduction and safety summary Chapter 1 1.1 Introduction and system familiarization Congratulations on your purchase of SIMRAD EQ42/50/52 MKII Echosounder and Fishfinder. Great care has been taken to create this innovative video sounder … both in design and performance. The EQ42/50/52 MKII is a unique new slim-line product in the Simrad Marine Line, and is available with a 10” ATFT (EQ42), 14” TFT (EQ50), or 15” TFT (EQ52) large LCD display in color.
EQ42/50/52 Introduction and safety summary Chapter 1 1.2 Safety summary Precaution The operating unit should not be exposed to direct sunlight, as “boiling” the display may cause too high temperatures internally and subsequently damage parts of the unit beyond repair. Quality service personnel The EQXX is sealed and does not contain any user serviceable parts. Opening of the unit will void its warranty. Touching electrical parts inside may cause bodily harm or death.
EQ42/50/52 Fundamentals & initial start-up Chapter 2 2.1 Fundamentals of the PAGE and WINdow system The EQXX Echosounder has a multi-function screen data presentation system. You can choose to have a full screen, or a screen divided into e.g. an echo display and two data/echo displays, etc. The display which is currently activated is indicated by a highlighted frame around the active window. There are five screen combinations to choose from: 1 2 4 3 WINdow 0 1. Full (1/1) screen. 5 2.
EQ42/50/52 Fundamentals & initial start-up Chapter 2 As many as 4 screen combinations or full screens can be saved in four pages.

The type of transducer selected (and installed) in the first two lines will also determine the frequencies. The EQXX features two transceivers, a 50/200 kHz (ECHO1) and a 38/200 kHz (ECHO2), which gives the following dual frequency combinations: 38+50, 38+200 and 50+200 kHz.
Operation of the EQ42/50/52 ! Chapter 5 Do not connect transducers containing speed log sensor e.g. Airmar triducer B744V to ECHO2 port, as this will cause the 1kW pulses to be connected directly to the speed sensor and thereby damage the electronics beyond repair! “Display” can show: DEPTH BELOW SURFACE, DEPTH BELOW TRANSDUCER, DEPTH BELOW KEEL. “Data on NMEA-out from” - select the frequency you wish to use for transfer of data to connected navigator, plotter, etc.

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. 8.1.
EQ42/50/52 Principles of operation Chapter 8 as echo transmissions are radiated at right angles from the transducer face. 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. The ceramic resonators in the transducer has a special property which enables it to change dimensions slightly when a varying voltage is applied.
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. The amount of focusing of the sound beam is expressed as a “beamwidth”.
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”. See Figure 3. 8.2.2 Effects of the vessel’s speed The display of fish on the EQXX depends directly on the vessel’s speed, as well as on the depth of the fish.
EQ42/50/52 Installation and service Chapter 9 9. Installation notes For a number of reasons, all user-related decisions, setups, etc. should be noted in these two pages as they occur. This information may be helpful if your unit has been updated with new software, reset or in for service.

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.

EQ42/50/52 Glossary of terms Appendix A Glossary of terms Alarms – can be set to sound a “beep” if the echosounder detects a target above (shallower than) a minimum alarm depth or below (deeper than) a maximum alarm depth. The EQXX allows you to set the alarm depths and to enable or disable both the minimum and maximum depth alarms. A-Scope – a method of displaying the echosounder information.
EQ42/50/52 Glossary of terms Appendix A marker as a waypoint in connected chartplotter, capable of receiving WPL. ) The EQXX must be receiving position data. Refer to Interface setup in section 7.2. Expansion (zoom) – this function allows you to take a closer look at a particular section of the water underneath your boat. You can expand the view near the bottom (Bottom expansion) or near the Variable Range Marker (VRM expansion). The amount of expansion can be adjusted in “Expansion window”, section 5.
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).
