As a mechanic/machinist/electrician, I've used a lot of measuring tools. I tried digital calipers but often batteries would die and I just couldn't get used to some "random" numbers appearing on a little display. I went back to dial (early Craftsman calipers I believe were made by Starret?). But, I did learn early if you purchase quality measuring tools, and take care of them, they will last you a lifetime (I had some Starret, 1", and blade, and Brown & Sharpe, ball and depth mics for nearly 40 years before they were stolen and they worked as good as the day I bought them...)
