Simrad ES 200-7
Transducer
(855-164298A
/
AA000 / 7-21)
Introduction
The ES 200-7 is a split-beam, composite trans-
ducer with a large bandwidth. This provides a fine
range resolution, which is important for single fish
detection and target strength measurement. The
transducer has four quadrants. The specifications
below are valid when all four quadrants are con-
nected in parallel.
