Pinger is designed specifically for shallow water sub-bottom profiling (as shallow as 4m and up to 300m in ideal conditions) and is intended for a simple over the side pole mount installation.The Pinger Wet End includes two separate interchangeable projectors - a low frequency 3.5 kHz projector for hard packed sand bottom and a 15 kHz projector for soft mud sediment sonar profiling - plus a broadband hydrophone receive array. A 200 kHz transducer is also included which provides a reference point as to where the bottom begins. This allows a wide variety of practical applications, including geophysical sediment research, harbour shoreline construction, and hazardous pond pollution monitoring.
The Pinger Dry End is a portable, black box system which plugs into the user's computer via a USB cable connection. The system is controlled through the KNUDSEN SounderSuite Windows application software which is supplied with the unit. The user will be able to view depth records in real time and record high resolution data onto their computer hard drive for archival and post processing.
The Pinger Sub Bottom Profiler is also capable of operating in Bathy mode. The Dry End system is equipped with a toggle switch, allowing operators to select between receiving on the large aperture array or receiving with the projecting transducer (additional transducers sold separately). If you have a requirement for a shallow water sub-bottom profiler, and need a standard bathymetric system for the same vessel, the Pinger is a good option to consider for your geophysical exploration.
