The Simrad ES120-4x10 is a split-beam transducer with 108 piezo-ceramic elements arranged in four quadrants. 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.
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.
