TRANSDUCER
Simrad ES 120-2.5x10
120 kHz Split-beam transducer
(855-164280 Rev.C)
Introduction
The ES120-2.5x10 is a split-beam transducer incor-
porating 172 piezo-ceramic elements distributed over
four quadrants. Its beam pattern has an elliptical cross-
section and the side lobes in the vertical plane are very
low. This unit is well suited for horizontal ranging
in shallow waters using the narrow beam in the verti-
cal plane. The following specications are valid when
all four quadrants are connected in parallel.
