Introduction
TheSimradES120-7CDisa120
kHzsplit-beamcompositetransducer
withalargebandwidth.Thisprovides
anerangeresolution,whichis
importantforsingleshdetectionand
targetstrengthmeasurements.The
transducerhasfourquadrants.The
ES120-7CDhasbeendesigned
towithstandalargewater
pressure.Itisthereforewell
suitedfortowedbodies.
