I would encourage anyone to use any decent climbing stick that is on the market vs. a screw in step. Screw in style is hard on trees, if the property is timbered it can effect the value of the timber, and IMO think they are far more dangerous. Worst thing you can do is leave them in the tree from year to year.

I used them for years because that was all we had. If you are going to use a hang on style stand I recommend sticks vs. screw in steps.
