<< Just out of curiosity, doesn't the WKPP use mk20's for stages and safeties? Is this due to having to leave them in the water, having the swivel for breathing the reg or both or neither? >> Kevin: You are correct. The following was posted by George earlier this year: "For stages, I use the MK20/G250 for deco and safety bottles ... Scuba Pro is a piston reg that will survive underwater forever (as on a stage or safety bottle), it has a very high IP, and drives the air balanced 250 ( which also does well left in the water for extended periods, but not too well out of the water) well for long durations with minimal cracking pressure, as on a deco bottle, and swivels for ease of operation on a deco or stage bottle. When it fails on such a bottle, it is no big deal since you can control the valve." Regards, Tod -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
