A sonar transducer assembly for mounting to a surface watercraft includes a rectangular first transducer configured to produce a first beam defining a fan-shape and extending generally in a first plane. The assembly further includes a rectangular second transducer configured to produce a second beam defining a fan-shape and extending generally in a second plane. The first transducer and the second transducer are oriented such that the respective first and second beams insonify different first and second areas each extending laterally with respect to a running direction of the surface watercraft, and such that the first beam is outside of the second plane of the second beam, the resulting planar separation of the first and second planes of the first and second beams reducing interference between the first and second transducers.
