Simrad ES333-7CD

Simrad ES333-7CD is a
333 kHz split beam echo sounder transducer

The Simrad ES333-7CD is a split-beam composite transducer with a large bandwidth. This provides a fine range resolution, which is important for single fish detection and target strength measurements. The transducer has four quadrants. The ES333-7CD has been design to withstand a large water pressure, and is therefore well suited for towed bodies.

Typical applications

  • Scientific echo sounders
