The Skeets gage is suitable for its intended purpose, checking chokes, and well worth the price. Accurate another thing. It has a 5 dollar Chinese indicator on a wood shaft with a metal rod inside.
Yours may have a wooden shaft, but mine and others I've seen don't. The shaft is brown but it is not made of wood. An ad at Midway for the newer digital model says the tube is aluminum covered with a resin based material. Hard for me to believe that anyone could actually think a device built to measure to .001" would be made with a wood tube.
