I've been out to the rigs before. Usually when people are busy spearing fish, they are not paying much attention to being buddy divers. I just wanted to know what kind of diving was going to be going on. I am very familiar with rig diving.
The water is not necessarily always clear either. You can have very low vis. I have been there when you couldn't get through the murk layer as deep as you wanted to go, so you really have to be prepared for low visibility depending on the currents and wave action that day, making it even more difficult with a moderate (1 knot or higher) current.
No doubt you've more experience with rig diving than I. I just know how difficult is is sometimes to fill a boat and not include spearos, unless a shop is scheduling a trip and says "no spearing".
