Query: Thin and inaccurate only measures outside diameter

Does not hold a candle to my old Central Tool Co. 4" Brass Caliper. Inaccurate on both the 1/16" scale and on the metric sale by about 1/32" and .2 mm on the metric scale. I should have read the reviews before purchase. I returned the caliper and will continue to search for one as good as my 1/32" & 1/64" scales on a pocket caliper
