International orders*The Ambient Recording TC4013 Miniature Reference Hydrophone is a miniature underwater reference microphone well suited for recording marine life, and other audio below the surface. The TC4013 features a broad-band frequency response of 1Hz to 170kHz, providing detailed fidelity in scientific exploration, film and video recordings, sound design and more. The TC4013's omnidirectional polar pattern is optimized for a generous pickup at the horizontal and vertical planes. The microphone is encapsulated with a specially formulated NBR (Nitrile Rubber) which provides maximum protection against fresh and sea water, as well as oil.
