Record high-frequency underwater sounds with our cutting-edge real-time smart digital hydrophones.
Small enough to carry in one hand, our simple, accurate, and reliable icListens allow users to collect, analyze, and listen to ocean sound data in real-time.
When deployed, the icListen gives you processed information to help with decision-making that needs to be done in the moment such as real-time detection of marine mammals or sounds from seismic surveying. It is also powerful enough to be combined into simpler or complex digital hydrophone arrays.

As the most reliable and user-friendly hydrophone available, understanding ocean sound has never been easier.

All of our hydrophones come with complimentary training.
