It often takes a lot of time and tweaking to use one of those "fast" digital powder scales.
My 45 year old beam scale settles in a couple-three seconds, no batteries or line power, no warm-up is needed - it's always ready to use, neither zero or calibration ever drifts and it's still as dead-on accurate as when it was new. But, I'm a fading dynasoar who doesn't always appreciate the LCD wonders of modern technology so what do I know?
