I do not have any course stuff here at the office today, but I seem to remember that the primary DM role in supervising tech divers was largely to ensure that non-tech divers did not accvidentally get the wrong tank (It seems that this was a test question?). I dive a plain looking tank that may or may not have nitrox in it. I doubt that anyone else is going to try to use it as it is attached to my BC as soon as I get onto the boat. How do you handle this type of situation? Do you look at tank stickers and c-cards for geezer gas or just "visit" with the divers to see what they are up to?
How do you feel about a totally non-tech DM supervising technical divers? For a recreational diver, I might test to see that their air is on before they make the plunge, but I would NEVER do the same for a Tech diver (I won't touch their valves). Also it would conceivably change the supervision role dramatically. What do you do differently if anything when supervising tech versus rec?
