The 2 step aider gets you more height out of a climbing aider than a single step, but less then a 3 step. The trade off here is ease of use. The longer an aider, the more difficult the climb can be. Get this aider if you want more height than a single aider provides but aren't quite ready for maximum aider length. Keep the 2 step climbing aider in your mobile hunting bag and use it when you need to get a little higher in tree or use it as part of your normal setup and remove a climbing stick or two. Two step attachment loops and a top rung that can withstand upward or downward pressure for one step sticks gives you multiple attachment and climbing stick options. Always use a safety harness in conjunction with this item.
