I used to buy markers for marking my stands, but the reflective portion of the Reflective Lifeline from Hunter Safety System is so good, I can see it from 100 yards away at night through timber and about 300 yards away if it's on a field edge. It saves me pulling tacks out of trees if I move locations. The cowbell-shaped cover on the carabiner is a great bonus, as it It helps fight noise and rust. Other brands don't have this. It's easy to install and offers a lot of security. It is just great to be safe from the bottom to the top of my treestand and back down.
