    How to use this manual? This manual is written for the products: EQ44 and EQ54, which share the same type of software. From hereon, these models are referred to as: EQXX. It is a good idea if you make yourself familiar with the key functions, menu structure and rotation of pages (screens) described in chapter 2 before you start out, and then proceed with section 2.5 Initial start-up.

  • Page 8: Safety Summary

    The lifetime of the internal battery is minimum 5 years. If not exchanged before it goes flat, all data in the unit’s memory will be lost. We strongly recommend that you have the battery exchanged at your local Simrad work- shop max. 5 years from date of purchase.

  • Page 21: Echosounder Operation

    EQ44/54 Echosounder operation Chapter 3-1 3. Echosounder operation The echosounder function of the EQXX determines the distance between its transducer and underwater objects such as fish, lake bottom or sea bed. It does this by utilizing the fact that an ultrasonic wave transmitted through water travels at a nearly constant speed of 1500 meters (4800 feet) per second.

  • Page 22: Parts Of An Echosounder

    Chapter 3-2 EQ44/54 Echosounder operation 3.1 Parts of an echosounder An echosounder is composed of a display screen, processor, and transmitter/ receiver 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.

  • Page 23: How The Echosounder Works

    EQ44/54 Echosounder operation Chapter 3-3 3.2 How the echosounder works When the EQXX is turned on, a transmitter begins to send electrical pulses to the transducer. The ceramic resonator in the transducer has a special property which enables it to change dimensions slightly when a varying voltage is applied.

  • Page 24: Transducer Beam Width

    Chapter 3-4 EQ44/54 Echosounder operation 3.3 Transducer beam width The transducer mounted to the hull of your vessel serves as both a ‘speaker’ when transmitting, and as a ‘microphone’ when the echosounder is receiv- ing. 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.

  • Page 25: Effects Of The Vessel's Speed

    EQ44/54 Echosounder operation Chapter 3-5 3.4 Effects of the vessel’s speed The presentation of fish on the EQXX depends directly on the vessel’s speed, as well as on the depth of the fish. When the vessel is at rest, the echo traces will appear stretched and flattened.
