If you need to obtain a clear picture of what lies below the seabed, look no further than the SeaKing Parametric SBP from Tritech. Sub-bottom profiling is now possible from this compact, low power unit, ideal for ROV and AUV use.

An innovative multi-element composite transducer array enables the echosounder to emit very low frequencies whilst minimising the size of the overall unit. Producing a 20kHz pulse, the system is capable of penetrating the seabed and highlighting structural differences that are hidden from view to conventional echosounders.

As with all SeaKing sensors, it is possible to integrate the parametric subbottom profiler in the ArcNet network, which enables the data to be displayed and logged on the SeaNet SCU.

The display allows the operator to view the raw 200kHz seabed profile, as well as the 20kHz sub-bottom layers produced by the parametric pulse.
