Just dropped $450 on a new ultrasonic thickness gauge. It found a bad spot I would have missed.
Was checking a boiler shell in an old plant, my old gauge gave a solid reading. The new one flagged a thin area behind a support bracket. Anyone have a go-to brand for these or stick with the old manual methods?

Solid reading" from the old gauge is my life story. My first one was so bad I'm pretty sure it just guessed based on how cold my hands were. Good to know the fancy upgrade actually works and isn't just reading tea leaves. I'm still using a backup set of calipers for my trust issues.

Oh man, @ben_wright97, I feel that! My old gauge would give me a different number if I breathed on it wrong. I finally bit the bullet and got a digital one last year, and it was a total game changer. I tested it against my buddy's pro-grade tool, and the readings were spot on every single time. It finally killed the urge to check everything three times with my rusty calipers.

Digital gauges are great for repeat readings, but they can drift over time without you noticing. My shop teacher always said analog tools fail in obvious ways, while digital ones fail in sneaky ways. That's why I keep my old dial indicator around to spot check the digital one every few months. It's not about trust issues, it's about catching battery fade or sensor drift before it messes up a project. A backup method is just smart, even with nice tools.
