Drunk_J, what is this o-ring mod for the V1 you're talking about?
Instructions on converting the Diver v1 from acetal to o-rings.
To reiterate: only remove the lower acetal, the one peeking out of the 510 connector at the bottom. The upper acetal, the one in the top of the base upon which the ceramic cup rests, acts as an electrical insulator, the Diver v1 will not work without it.
