제품설명

Main Feature

Low Frequency Acoustic Source

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 flextensional motion

Reliable, robust, high performance, low frequency transducers

Applications

High power low frequency acoustic source

Ranging Applications

Sound Navigation
