Warning: spent $80 on that sonic silt density gauge...

Bought one of those sonic density gauges from a supplier in Baton Rouge for $80 thinking it'd save me time on fine-tuning my slurry mix. Ended up being way off compared to the lab sieve test I always run on samples. Has anyone else had bad luck with those things burning you on accuracy?

Oh man, that really stings. I feel your pain on that one.

Did you calibrate it before using it?

Actually I used to skip calibration on almost everything, figured it was just a waste of time. But then I borrowed a friend's meter that wasn't calibrated right and it threw off my whole project for a week. That changed my mind real quick.
