I did a doubles mini course recently to learn how to setup and use doubles (in OW only). I must have been a bad student 'cos now I have many questions
Not much change to S-drill, but now there is valve drill.
Ok so I've practised the valve drill repeatedly. But funny thing is, how do I use it? After the course I realise I have no idea, because I was just taught the steps of the drill and made to practice it by rote, but no application.
I guess I can figure out simple stuff. If right post leaks, shut off and go to necklace. Same for left post, shut off but remain on long hose. But when do I shut off the center knob (what's it called again)?
Also some questions on the hardware. If I shut off right post, gas from right tank is still accessible through the manifold, correct? It just doesn't send gas to the longhose 2nd stage?
The centre knob isolates the two cylinders, effectively making them independent? When will I need to do that?
Thanks for your help.
