Easy Meg Calibration Revisited
or
Even EASIER Meg Calibration on One Liter of O2

Most divers seem to be always changing their rig's set up in a never-ending quest to make the overall package lighter, tighter, and more reliable. For me, I confess it is almost an addiction. It's been close to 2 years now since I posted the calibration plug article, and all who have used one in the field seem quite pleased with it. The following short article shows how to make this small bit of the system even easier to use and more bullet proof in transport.

The polycarbonate flow orifice is far from fragile but it can be broken by baggage gorillas or falling tanks. I was sitting at the workbench a few months ago, sketching up various ideas for protective housings, when I dawned on me I'd already built one. The flow orifice can be protected by the body of the plug itself. This set up uses the original plug with NO changes whatsoever and reduces the parts count on the remaining bits. Beyond the original plug body and its O rings, all that's needed is the flow orifice, ½ inch or so of ordinary clear vinyl tubing (1/4 inch OD x .17 ID), and a 1/8 inch MNPT-to-BC conversion fitting. Finally, a small dab of 3M 5200 sealant will be needed as well.
