Underwater ROV Add-Ons
Listen and record audio underwater. The hydrophone has a wide range of frequencies, with the ability to hear something as low as the Earth’s tectonic movements up to the sounds of different marine species.


Underwater Passive Listening Device for Listening and Recording Audio from Wide Range of Frequencies

  • Real-time Monitoring
  • Integrated into BRIDGE
  • Mountable to DTG3 & REVOLUTION ROVs

Customers use this device in ocean science applications where they are monitoring species patterns and health by listening for them, it is additional data on top of visual data and sample data to help identify species behavior and trends. The Hydrophone mounts to the top or bottom of the DTG3, or the bottom of the REVOLUTION ROV.
