Excellent tool. I have used it quite a bit
Excellent tool. I have used it quite a bit. It's far far better than using the depth measurement device on my calipers. I wish I had bought one earlier!

Didn't come with the right pins.
I never got a 0" pin and it's a 0"-3" depth mic, so it's mostly useless without it.

non-rotating blade micrometer
I purchased this for gunsmithing applications. The non-rotating blade is perfect for measuring barrel shoulder depth from the breech face. The blade can be rotated by hand for the proper position and by "non rotating" that means the blade does not turn as the mic is measuring; the blade will not torque "off" the shoulder.
