Just realized my old method for checking sand moisture was way off

A guy at the regional conference in Toledo told me I was basically guessing by just squeezing a handful. He said to always use a proper moisture teller and aim for 3.5% for our green sand. I bought one the next week and my scrap rate dropped a ton. Anyone else have a tool they resisted that ended up being a game changer?

Oh man, this reminds me of my buddy's shop. He was the same way, swore by the hand test for YEARS. Then his new hire, a kid fresh out of trade school, basically staged a mutiny and demanded a digital pyrometer. My friend fought it hard, called it a toy. But the kid was right, @amyr57, it's exactly like your moisture teller story. They were running everything way too hot and couldn't figure out why their finish was so bad. That one tool showed them the truth instantly. Sometimes the old way is just the stubborn way.

Wait, you were just squeezing it by hand before? That's wild... I can't imagine running a whole line like that. The moisture teller feels like cheating, it's so much easier. My boss fought getting one for years, said it was a waste. Finally caved and we cut our rework in half, just like you said.
