Understanding ocean sounds has never been easier with icListen and our data analysis services.

Introducing Launch Box


Using smart hydrophones is now even easier thanks to Ocean Sonics’ new Launch Box. Launch Box is a compact, portable deck box created to ensure your sound data collection is as simple, effective and reliable as possible. Contained within the weatherproof box is WiFi capability, GPS time synchronization and extended power to icListen or any 24 volt ethernet device. Launch Box transmits data wirelessly to your computer up to 100 meters so there is no need to cable the device to connect to a computer.


Created to simplify hydrophone deployment, Launch Box can be used with a single hydrophone or for creating multi-hydrophone arrays through smart cables. By eliminating the physical connection to your PC or smart phone, you can relocate your equipment to where it remains safe and dry.  Operation time has been extended as Launch Box provides additional power to connected hydrophones while built in GPS capabilities allows you to accurately time sync your data and record its position.

The icListen smart hydrophone simplified life for hydrophone users, Launch Box takes it one step further, simplifying and streamlining deployment and data collection. At Ocean Sonics, it’s our goal to make the most reliable and easy to use ocean acoustic systems. With Launch box in your arsenal, collecting and understanding ocean sound has never been easier.
