Really??? Just how common is it to crash into something so hard that you knock the knobs right off? In your videos, George, I've seen you and JJ driving full speed through restrictions on fast scooters. Do you often crash into the sides? I'm just curious how common is "common".

I dive an OMS rig because when I bought my manifold, Dive rite didn't sell one rated to 300 bar. When I phoned them, they said, "Off the record, sure you can use it, but you have to change the burst disks, yadda, yadda, yadda." Also, the way I understand the OMS system, it uses a captured O-Ring similar to the way the DIN on the regulator uses when screwed into the post. How could this be bad when used on a manifold, yet good when used on a reg? > -- > Send mail for the `techdiver' mailing list to `techdiver@terra.net'. > Send subscription/archive requests to `techdiver-request@terra.net'. > -- Regards, Andy W.
