The Simrad ES120-2.5x10 is a split-beam transducer incorporating 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 vertical plane.
These specifications are valid when all four quadrants are connected in parallel. Note that the specifications can be altered without prior warning. For a full set of specifications, see the data sheet.
