"..continue using my beams(over 35 years old) or buy a digital scale.
What do you know, and are they worth buying?"
Opinon: Digitals are the current fad and when someone gets a hankering for a new gimmic I would never say, "Don't."
Fact: As a retired electronic insturment tech in the space/defence industries, I won't.
I continue to wonder, what is a digital scale supposed to accomplish that I can't do with my 45 year old 1010, which is still as dead-on as the day I bought it and expect it will be so another 45 years from today. (Anyone want to say their digital anything will equal that dependabilty?) Obviously, those who get "good" ones love them - now - but, still, they are vastly over priced and what do they do that a beam doesn't, and with much more security and ease of use? IF I had surplus cash spilling outta my wallet, and I don't, I MIGHT buy one for weighting bullets and cases. But, since I quit doing that long ago, it would mostly be an expensive trinket to decorate the loading bench.
Reloading grade electronic scales ain't high grade scales. High grade scales for drug and grocery stores, labs, etc., are EXPENSIVE! AND they still have a trained technician come in one to three times a year to test and adjust them, but NO reloader ever gets his digital scale tested/adjusted after purchase.
Digital dumpsters, aka, RCBS Chargemasters, etc, are not, per se, "scales". And they too are vastly over priced! If I had one, I too would use it to dump charges just under weight and trickle up, on a beam, to what I wanted. I'd NEVER trust one of those things to set my hot charges, all it would have to be off is ONCE! I KNOW what I will do and I do not trust any electromechanical gadget to do it for me.
No matter the room temperature, I can walk up to my mechanically leveled 1010, set a weight on it and know it's going to read properly, right then, every time. It works on gravity and, unlke power line voltage, that never changes and it isn't sensitive to external electical fields. All it needs to maintain accuracy forever is proper handling to prevent damage and an occasional cleaning to remove dust from the pivot knife and vee bearings.
With a "fast" digital scale, I would have to turn it on and allow it maybe 15-20 minutes of warm-up time. Then tare it, zero it and test the calibration. Then I could check my weight and, who knows, it may tell me what it really weighs. But, if I continue to use it for an extended loading session I would have to rezero it and recheck calibration from time to time. And that thing is supposed to SAVE TIME! ???
Nope, uh-uh, others may love them but they ain't for me. But...the folks who sell them digitals need to make a (good) living too, so...YOU get one!
