TECHNOLOGY FOR SUSTAINABLE FISHERIES

ES80 ECHOSOUNDER SIMRAD has manufactured fishfinders for more than 70 years and has 25 years of experience using Split beam technology. The first Split beam fishfinder, a 38 kHz model, came on the market in 1984, quickly followed by a 70 kHz model. Today, SIMRAD has a wide range of frequencies from 18 kHz, used for detecting deep water species, up to 333 kHz used for measuring plankton. The Simrad ES80 is the fifth generation Split beam fishfinder where the latest in computer and signal processing technology is used to satisfy the increasing need from our demanding customers: “Top performance...

WIDEBAND ECHOSOUNDERS The new series of ESs have wideband capabilities. That means that you can transmit a signal that varies in frequency across the transmission. The most common way to operate the sounder is to use linear FM, or chirp. In an ES80 chirp transmission you utilize the effective frequency band of your transducer, starting low and continuing higher until you reach the frequency where the transducer efficiency drops off. suited for such environments. The ES80 has this capability and, as the SW continues to be developed, new functions would be available. Due to advanced matched filtering...

ES80 DETAILS MAKE THE DIFFERENCE The ES80 comes standard with digital CW transmission. This is the transmission form that has been used since SIMRAD, as the industry first, digitized the echosounder back in the mid 80’s. Then it is possible to add a FM transmission module to the system, making the ES80 a true chirp echosounder. The advantage of chirp is that it is possible to transmit with a very short pulse length at very long ranges giving maximum resolution. What determines a good chirp echosounder, is how long range it gets on the shortest pulse. In addition to this, with the long experience...

The Wideband Transceiver (WBT) is designed for applications where performance is the top priority. The WBT has four 500 W channels that can either work independently with single beam transducers, or together with a split beam transducer. The WBT transceiver is capable of operating on entire band from 10 kHz to 500 kHz, only limited by the transducer's bandwidth. The WBT is operated by the ES80 SW, and depending on the settings it can be used either in narrowband or wideband mode. The WBT itself is capable of doing CW, FM and also user defined signals.
