We use the " Treehopper" bolts on 15-20 of
our trees and they work great. For the last 2-3 steps,
we usually try and use screw in steps. Also, some
trees that are a bit awkward, like really big
oak trees, you are probably better off using
screw-in steps.

As long as the steps(bolts) are not too far apart,
and you take your time, they really are quite
safe, as well as, convenient[:-].

We bought our drill bit from Treehopper at the
Iowa Deer Classic a couple of years ago, in
addition to 15 bolts each that come in a pouch.
We wanted to buy a second bit, but the number
I have has been disconnected.

We usually can drill between 24-30 holes with one
battery (14.4 v), which equals about 2 1/2 stand
sites.
