제품설명

Main Feature

6 Flexural disc transducer stacked vertical

Higher Power Low Frequency Acoustic Source than single FDT

Horizontally omni-directional

Longer Range

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
