Many of you know I dive a double hose regulator frequently and during some conversations about diving them, the observation was made that most divers have never seen anyone diving one, let alone dove one. I am sure a lot of the guys from the vintage forum see them, I do all the time but I am almost always diving with them or at least know them. If you have been diving since the 60s or early 70 then you likely have seen one back then. What I am interested in is, have you seen anyone diving a double hose reg, vintage or the modern one, in the last 10 years or so. Obviously you would see them at a vintage event or such....if you were at Sand Dog I know you saw some , what I am interested in is, have you seen anyone diving one on a routine dive and if so where? This is purely curiosity on my part.
