Introduction
The ES 200-7 is a split-beam, composite trans-
ducerwithalargebandwidth.Thisprovidesafine
rangeresolution,whichisimportantforsinglefish
detection and target strength measurement. The
transducer has four quadrants. The specifications
below are valid when all four quadrants are con-
nected in parallel.
