Demo of “PINGER” Sub-Bottom Profiling System


Knudsen Engineering put its new 15 kHz “Pinger” sub-bottom profiling system through its paces on Lake Champlain, Vermont with the support of Middlebury College on their research vessel R/V Baldwin. Data processing was performed with Chesapeake Technologies SonarWiz 5 software.The Pinger features chirp transmission and a large aperture receiver using the latest PVDF technology that provides higher directivity while remaining lightweight. Designed to be portable and lightweight the Pinger is suited for small boats and shallow water applications. During the demonstration the Pinger was operated in water as shallow as 1.5 m. Two experienced observers onboard during the demonstration, Tom Manley and Garry Kozak both agreed the data was very good and produced results that rivaled conventional large heavy SBP systems. The lightweight system will open up new possibilities in shallow water for surveyors.
