HTI-99-UHF Hydrophone

The HTI-99-UHF is a high-performance free-field hydrophone designed for use with SonarPoint recorders. Mounted on a cable and positioned several meters away from the recorder, it delivers high acoustic fidelity and accurate measurements while minimizing reverberation effects often associated with end-cap integrated hydrophones.
