Supplied without instructions. You have to guess how to set up the master and push against the wall. If it's not a flat surface to start with, don't expect straight lines. The tripod he walked with is so weak it can't hold the scales. The legs keep falling. I can't regulate the tension in my legs. It feels like something cheap can be bought in a store for 0.99 cents. As a result, I got the usual old level. Works much better. Do yourself a favor and don't waste your money on it.
