The GeoSpectrum Technologies M511-200 GuardBuoy is a high-performance passive listening buoy capable of real-time embedded signal processing for autonomous detection of marine mammals, marine traffic and many other underwater noises.
Unlike other high-performance buoys, the performance of GuardBuoy does not come at the expense of high-power consumption and short deployment times. GuardBuoy can synchronously sample up to four hydrophone inputs at over 500 kHz to handle just about any scientific requirement.
This buoy has live Ethernet for real time research, Bluetooth for configuration and highspeed USB for ultra-fast data downloads.
