I mostly just need the chemicals and a touchstone for gold and silver, though a diamond tester if cheep would not be a bad thing to have. As to the scales I already have a few including one that's lab grade. The loupe at 30x is a bit strong for a hand held, for 20x and up a scope is best I have bought them at tag sales my current one is a Nikon zoom that's 8-50x and like your Nikon stuff I found it curbside
