Hi all,
I am very new to DIR and have my fundies booked with Brian in August. I have already got my kit and twins set up in acceptable DIR config and am happily getting used to it but I am constantly having arguments with one of my dive buddies about the correct set up for twins. Basically, without opening up a huge can of worms (hence posting here and not on YD) I need a definitive reason why we use twins fixed “upright” instead of inverted.

The problem is my buddy is Ex Royal Marine and is a very accomplished recreational diver. He is also wanting to go down the twin route but insists that he will use his twins inverted as that is the correct way. He cites the Royal Navy divers as an example and also make a very good case for bio-mechanics (in that operating valves on inverts is far easier and “natural” for our limbs than with uprights). He states that entanglement issues are the same with both and that hoses will route over the shoulder in any case.

I can’t seem to find a satisfactory and definitive answer to his question as to why DIR divers set them up they way we do and not inverted. I just need that convincing reason to give him.....Can anyone help? As with most DIR questions I expect the answer to be blatantly obvious once I know it and I promise to go stand in a corner with the Dunce hat on….!

Thanks
