Rumors
GUE China, runs by Denovo and others, are believed to be actually managed by UnitedScuba, a for profit company.
Out of the 8 dive crews, at least 4 work/affiliated with the Shanghai dive shop, which indicates who the "organizer" is.
UnitedScuba's GUE Fundamental instructors were conducting GUE Fundamental course over there apart from mapping the area.
United Scuba is a profit-seeking company, who also distributes Halcyon products in the country.
