Idano, hi bro. Naw, ain't no enginner, just found this old hat. Was a PMEL repair and calibration tech, to NBS standards, at Cape (then) Kennedy in the distant past. Didn't do a lot of scales but did a few. I just don't trust electronics. Trust pnuematics and hydralics and gears, but not electronics! ;-)
Seriously, I really don't see any user benefit to digital reloading scales EXCEPT faster readings of widely varing items such as cases. They have too much hysterisis to follow a trickler, at least the one I really tried to use did. Digitals are much more expensive, just have to be more tempermental and are no more accurate. And they surely won't last as long either. ????
My old Ohaus 1010 only swings a couple of times and the magetic field stops it, dead on, that's plenty fast enough for me. Then it follows the trickler in real time. I have no problem with line voltage or warm up. Setting at eye level, it's very easy to read the beam pointer. Nothing but wind affects its repeatablily and accuracy but that's true of any scale. What more can I ask of a reloading scale?
