Acoustic Zooplankton Fish Profiler (AZFP)

A powerful tool for scientific research and environmental monitoring in oceans, lakes and rivers.

Using onboard data storage, the AZFP can collect data continuously for periods of up to one year at high temporal and spatial resolution. The AZFP is available with up to four frequencies in a single transducer housing. It can be operated in bottom-mounted, upward looking mode or in downward looking mode from a buoy, and is ideally suited for taut-line mooring operation, but many other options available. The AZFP has highly configurable sampling programs.

Examples of simultaneous data at up to 4 frequencies from downward looking AZFP
