Review on Mitutoyo 050103 Center Finder Diameter by Steven Loy

I like this model better than my school finder [unnamed brand] which doesn't have a center pointer. Also, I like it better than my B&S/Tesa which only has one small side and does NOT use the opposite side to use 0.5". there is a cap screw. The only issue with this item upon arrival was that it has a thin "edge" on the polished surfaces [pointers and level] facing the "viewfinder blade". This will obviously give the wrong mean value. but it was easy to polish with porcelain stone M/F
