Simrad has introduced a next generation split-beam composite transducer designed primarily for deep-water research applications and ecosystem monitoring.
The new 120 kHz Simrad ES120-7CD transducer can operate in water pressure down to 1500m, enabling scientists to collect improved data on fish species and smaller targets such as zooplankton.
The traditional use of the scientific echo sounder has been fish stock assessment typically based on hull mounted transducers onboard research vessels, but the ES120-7CD is suitable for installation on towed bodies, AUVs, buoys and landers, enabling scientists to look deeper than ever before.
Recently, it has been documented that by using many acoustic frequencies it is possible to discriminate between species, identify species and study species interactions. With the new ES120-7CD, the Simrad series of pressure resistant transducers is now suitable for even more scientific and fishery research applications.
