They include the QTC5 single beam series for both shallow and deep water operations and QTC Multiview TM postprocessing software for multibeam applications. The latter is claimed to provide advanced techniques for data cleaning and removal of artefacts by way of compensating for grazing angles and range issues.

The systems will also be shown by Atlantas Marine at this month's seawork Exhibition together with other subsea equipment designed for general survey, inspection and diving work.
