Accessories for the Smart Hydrophones & Smart Projectors


Float Collar

Easier to deploy than a tripod, just insert the icListen Smart Hydrophone into the Float Collar and lower it over the side of a dock or boat. A small 10kg anchor is enough to hold it in place in the correct orientation. If its bumped, it will move away and slowly return to its resting position. Our float collar is designed to be quiet, preventing collection of undesired ocean sound.





Sync GPS Master

Ocean Sonics offers a Sync GPS Master which allows the icListen to be synchronize by receiving a GPS pulse per second (PPS). The system is very low power, small and can be mounted on a mast above water or on shore. Typical PPS can synchronize the seconds to a resolution of nanoseconds. However, the Sync GPS modulates the trailing edge of the PPS signal to encode the date & time as well. This guarantees that all instruments are fully synchronized to GPS time after two minutes.




Ocean Sonics Drifting Buoy

Collecting ocean sound data has never been easier with the Coastal Acoustic Drifting Buoy. Designed with the user in mind, the buoy weighs in at 23KG and measures 1 meter in length and 0.5 meter in width and is easily deployed by a singular user without the use of a crane or any additional equipment.  Features include Wi-Fi for real-time set-up, status and spectral display, remote WIFI access (up to 100m), GPS time sync, on/off switch for icListens and buoy, and hydrophone synchronization within one microsecond.

Designed to be acoustically quiet, this buoy has the ability to drift and collect data or to be moored. While drifting the buoy reduces flow noise to improve quality and clarity. With configuration for up to 6 hydrophones or other ethernet devices, this buoy integrates easily into any project.












PTP Cans

If you are using the icListen on a network, you can synchronize that hydrophone to others to create an array of icListen Smart Hydrophones, or you can synchronize your acoustic data to other instruments. The IEEE 1588 Precision Timing Protocol can support timing accuracy of up to 1 usec. Actual timing accuracy depends on network quality and latency.

The Ocean Sonics PTP is compatible with most PTP network masters. It connects in-line between the network connection and the icListen. It supplies a sync PPS signal to lock the network timing to the instrument. No special software or configuration is required.


icLink Smart Hub 

Simplify large or small arrays by connecting multiple hydrophones or even an icTalk smart project to icLink. The icLink smart hub introduces the concept of a self contained mini-observatory with the ability to connect complimentary sensors.

Higher power hubs for larger arrays, up to 32 channels, are available. Use repeaters and extenstion cables to deploy your array up to 500 meters away from shore.

For long cable runs icLink replicates the GPS timing signal  (PPS) using IEEE 1588 PTP


Launch Box

Using smart hydrophones is now even easier thanks to Launch Box, 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.















In-Line Battery Pack 

Thanks to its smart design and extensive testing, the Ocean Sonics battery pack  is easy and safe to use, making it the perfect tool for powering a wide range of ocean instruments.

Powered by field changeable D size batteries, these battery packs are compatible with either lithium or alkaline batteries. Ocean Sonics battery packs are depth rated for 200m, 900m nad 2500m and have a battery life of 30 to 90 days for a single channel unit.

Compatible with any 24 volt equipment and featuring 5 ports with standard MCBH-8F connectors these battery packs are easily integrated into any project, including mooring ocean observatories and autonomous arrays.

Self contained and easy mounting for longer deployments, use with Ocean Sonics In-line Battery Pack Frame to make underwater sound measurement even easier.
