The ES70-11 is a split-beam transducer in a streamlined housing. It can be mounted outside the vessel hull or on a towed foil. The transducer has 36 piezoceramic elements arranged in four quadrants. It can also be used as a single-beam transducer by connecting the four quadrants two and two, first in parallel and then in series.
(Specifications valid when the transducer is wired as a single beam unit.)
