I am talking the kind that had two screws, not the slip on type. I have used my last one. I think Trident makes one but I cannot get that catalog to download over my satellite connection.
Did y'all know, I think, that USD said those type of Calypso and Conshelf were dangerous? I think they did. I cannot find that source right now?
I use these mostly for seconds on my double hose rigs because they are more compact that the slip on type Conshelf seconds. And super performance is not a requirement, just get me back to the surface or assist an OOA diver is all they need to do. But, the dang exhaust tees .
The diaphragms in the vdh store fit these dandy.
I was able to get in the pool a few days ago with scuba gear and used, among other things, my first regulator, a Calypso J 1966 model. It is not vintage anymore since I had to replace the LP hose and the new diaphragm but it looks just like it used to once again. I would not dive the Spiegal in a ripping current with it but now just as in those olden times, it would be a blast over the grass beds out of Keaton Beach, barely 20 feet.
