How do you find accuracy of the preciray/park tool compared to each other? I understand the pointers are x10 magnification, what does that equate to on your dials? Do you use the preciray to get a “working wheel” and then dial in closer, or is the accuracy the same?

I am going to France this summer……I will be scouring French websites before I go….just missed one on ebay in the UK, dammit!
