It's not referring to the industry vis. It's referring to a visual inspection done by the Hydro technician as we would call them, or the "restester" as they call them.
I know. That's why I wrote: "VIP is a legal requirement... mandated by DOT in the United States, as part of the hydrostatic testing procedure". I didn't say anything about the dive industry VIP. I was specifically responding to the poster that said a hydro shop would only do a VIP-lite (at best). That's false. The retester must meet the CGA requirements.
