Here's my thinking on digital scales...
• They
are faster, but let's consider how they are used. You decide to reload 200 rounds. You use the scale to setup the powder measure. Then you reload your 200 rounds. So the "faster" scale has saved you 2 minutes, but the reloading took 20-40 times that amount of time. So if you look at your total reloading session length, there's really no appreciable difference.
• They are great, but when they start to wander they give no outward indications. That's why you need a session with the check weights before starting.
• They are affected (or should we say
afflicted) by everything you can't see.... drafts, magnetic fields, power fluctuations, etc which makes it hard to prevent trouble.
Don't get me wrong... I think everyone should own a digital scale. I simply think it should be their second or backup unit. If you find a bullet on the floor and you want to quickly see which box it should go back into, then a digital is nice to have.
