The way we handle green sand moisture changed after a bad pour in Toledo

We used to just go by feel and a quick squeeze test, but after a whole batch of scrap castings from a job in Toledo last fall, I got a proper moisture teller. It's a little digital gauge from Wagner, and now I check every batch before we start molding. The difference in surface finish on the cope side is night and day... Has anyone else switched to using a meter, or do you still trust the old hand methods?

Had a similar thing happen with treated lumber. Supplier sent a batch that felt dry but the moisture content was way off. Warped every fence panel we built that week. Now we use a pin meter on every delivery, no exceptions.
