Saxon Progress was the industry catcher vessel working in tandem with the Southern Surveyor during the July-August 1999 orange roughy research voyage at St Helens Hill and St Patricks Head. The acoustic system comprised a Sonardata Echolistener unit that digitised and recorded the output of the Furuno 28kHz commercial fisheries sounder.
