    EQ33 Echosounder operation Chapter 5-1 5. Echosounder operation The echosounder function of the EQ33 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 47: Parts Of An Echosounder

    8.1 Parts of an echosounder An echosounder is composed of a display screen, processor, and transmitter/ receiver unit which in the case of the EQ33 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 48: How The Echosounder Works

    Chapter 8-2 EQ33 Principles of operation 8.2 How the echosounder works When the EQ33 is turned on, the processor 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 49: Transducer Beam Width

    EQ33 Principles of operation Chapter 8-3 8.3 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 50: Effects Of The Vessel's Speed

    EQ33 Principles of operation 8.4 Effects of the vessel’s speed The presentation of fish on the EQ33 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.

    Chapter 9-8 EQ33 Installation and service shielding is maintained, that cable of adequate cross section is used, and that all connections are properly made and protected from the effects of the marine environment.

  • Page 61: Determining The Position For The Transducer

    9.6.2 Determining the position for the transducer The EQ33 is a sophisticated piece of electronic equipment, but how well it will perform under actual operating conditions will be largely dependent upon the location of the transducer and how it has been installed.
  • Page 62 Chapter 9-12 EQ33 Installation and service which holds the transducer away from the hull and which directs the flow of aerated water around the sides of the transducer rather than over the face of the transducer. On deep keeled vessels, care must be taken to ensure that the transducer beam will not be blocked by any part of the keel.
