Main Feature

Flexural disc transducer

High Power Low Frequency Acoustic Source

Compact and small weight.

Horizontally omni-directional

Can be used as projector at depths of 10m or greater to ensure a sufficient amount of pressure is placed on the transducer due to the flexural motion.

Reliable, robust, high performance, low frequency transducers.
