Capture & Identify Underwater Sound

Spotter Sound

Starting at $17,355

Add an AI-enabled hydrophone to your Spotter Platform to monitor underwater sound and detect marine mammals and vessels in real time. Process data at the edge using built-in AI models or deploy your own algorithms for custom detection needs.

What is the Spotter Platform?

Spotter is a modular, rapidly deployable marine sensing platform that delivers real-time surface and subsurface ocean data to power better decisions.

What is Spotter Sound?

A turnkey solution for real-time underwater acoustic monitoring. Ships globally, deploys quickly, and transmits sound data instantly.
