icListen Smart Hydrophones are the world’s first digital hydrophone. Use the icListen for real-time listening and event detection, or as an acoustic recorder. icListen internal processing capabilities saves you time and provides you with the most accurate data possible, without the need for onerous gain settings.

Small enough to carry in one hand, allowing you to deploy with smaller craft, or deploy on autonomous vessels.
