This probe is similar to my grandfather's probe and believe me it's a good thing. It seems (and still is) made at a time when American artisans were proud and devoted to their work. It's a very solid feel with electroplated brass and from other reviews I've seen online this is a very accurate gauge compared to known pressures. It's not cheap made in China, use it half a dozen times and throw it away like a modern 'tool', it will most likely last a lifetime and I'm glad to own it. Well done Milton.
