was wondering if these testers are good. if some one has used these could you give opinions please, looking at testers for scrap gold. either Kee gold tester Mizar Electronic Gold tester GG-Gemoro AuRACLE or if there is another option in the $500 price range
Yes I use that technique also. its good but not so much on the fly with scrap Also use acid test. but thinking a tester would be more suitable so keen to hear what people who have one of these machines think.
