@invictus005 That's not true, Mint is a pience of plastic for $130, there is no pivot to spindle measurement "on the fly" for ANY tonearm. Also MINT for its price does not have ALL 3 Alignments (Baerwald, Lofgren, Stevenson). Dr. Feickert's second generation of protractors is the winner in all aspects and i don't see/feel any disadvantages, it's dead accurate. Feickers buld like a tank, it's metal, not a piece of plastic. Only idiots can't handle Feickert's protracktor (flashlight included in the deal). Feickert is also a turntable manufacturer. It's German quality, it's machined with absolute accuracy. The price for Feikcert on the used market is unbeatable by any other protractors. Go figure!
What do you meant "much more accurate" ? The protractor is acurate or not. Did you ever tried Feickert ?
