Simrad ES333-7CDK

The Simrad ES333-7CDK is a compact single- or split-beam transducer. The transducer is mainly designed for underwater science applications.


The ES333-7CDK transducer contains a 333 kHz that can be used as a single- or split-beam transducer. The split-beam version offers three individual sectors. The nominal operating frequency is 333 kHz and the beamwidth is 7 degrees. Both versions are created for a maximum of 1500 m depth. They are designed to be deployed on submerged platforms for underwater science applications.

The transducer is especially well suited for use with autonomous and subsea products such as the WBAT (Wide Band Autonomous Transceiver), WBT Mini, and WBT Tube.
