Introduction
The Ocean Sonics Coastal Acoustic Drifting Buoy is an easy way to deploy one or more
icListen Smart Hydrophones while keeping them synchronized. Users can create a custom
array using the extension cables and Smart Cables as building blocks. The setup and
configuration of the hydrophones can be done with the buoy's internal Wi-Fi access point.
The yellow drifting buoy is small and lightweight, so it can be deployed from a small vessel
by 1 or 2 people. This solution combines power, Wi-Fi, and time synchronization with a
hydrophone array.
Important Notes
•
Buoy battery life will depend on set-up of deployment,
number of hydrophones and smart cables.
•
Do NOT allow the batteries to deep discharge
if the buoy does not have a low voltage cut-off module.
Batteries should not be discharged below 21 V.
To confirm the battery voltage, see
•
Turn the buoy OFF when not in use.

Stand the buoy upright or lay on its side.
•
Do NOT flip the buoy or turn upside down.
