TRANSDUCER
Simrad ES 120-4x10
120 kHz Split-beam transducer
(859-130990 Rev.D)
Introduction
The ES 120-4x10 is a split-beam transducer with 108
piezo-ceramic elements arranged in four quadrants. The
speci cations below are valid when all four quadrants
are wired in parallel. The beam pattern has an elliptic
cross-section suited for horizontal ranging in shallow
waters with the narrow beam in the vertical plane. The
side lobes in the vertical plane are very low.
