PINGER Sub-Bottom Profiler

15kHz Data

PINGER SBP, a new product offering by Knudsen Engineering, will provide researchers with an alternative to the challenges of shallow water sub-bottom profiling. PINGER’s large aperture receive array provides higher directivity in a more lightweight package

PINGER also gives the user the advantage of a wider bandwidth which allows simultaneous operation at multiple frequencies. The above graphic shows data collected transmitting and receiving on the same transducer compared to data collected with the PVDF receive array of the PINGER SBP.
