I know this belongs in the Classifieds section. But, since there are so few CCR divers here, I figured I'm make mention of it in the Tech section. I have two (2) Meg calibration plugs up for grabs. I was hoping to get around $70 each for them. Anyone interested? DEEP THOUGHT?

Thanks,
John

Thanks John,

I still have the original one that Ken Swain made for me, these are copies of his design. Unfortunately my students have just recently purchased their own cal plugs, but thanks.

Good Diving

Ron,

I am familiar with Ken's design. These are copies only in external dimensions only. The internals and metering orifice are entirely my design. Also, I haven't seen how well one of Ken's performs. But, I've had a lot of luck being able to calibrate simply from charging my O2 hose, turning off the tank valve, and using the gas in line to calibrate.

However, both have been sold.
