Introduction
TheSimradES333-7CDisasplit-
beamcompositetransducerwitha
largebandwidth.Thisprovidesane
rangeresolution,whichisimportant
forsingleshdetectionandtarget
strengthmeasurement.Thetransducer
hasfourquadrants.TheES333-7CD
hasbeendesigntowithstandalarge
waterpressure,itisthereforewell
suitedfortowedbodies.
