Fliers are there because something in the load or you're shooting was different. Having a good scale can eliminate that variable so you can move on to the next one. If someone told long ago that for $450 I could have done away with a ton of wasted trips to the range, wasted bullets, wasted powder, wasted time, etc. I would have said no way. After all the beams, Chargemaster, Gempro, Accu-touch, etc I bought an FX-120i and it never drifts like a Gempro 250 and you don't have to pick up the pan and set it down again. The Gempro won't register a kernel being placed in the pan unless you pick it up and set it back down or touch it with tweezers. Then 10 cartridges later when you put the empty pan back it reads 0.08 or -0.06. You really have to stay on top of it.
With a good scale you can weigh powder, bullets, brass, etc. accurately, reliably, and FAST eliminating those variables from your equation.
My life is simpler now and I would have paid twice that. Ask anyone if they regret upgrading their scale. Maybe I'm wrong but I certainly consider mine well worth the investment.
