Manson Gauge Question?

[Bob Brown]

Thanks very much, John. Now to find one and learn to use this thing. I hear they can be a bit tricky to get the hang of.

I posted a tutorial on the Manson gauge a few years ago. It was on this site or on Doublegunshop.com. A search may turn it up. My purpose was to teach the horizontal method rather than the difficult vertical method used by so many owners.
