The 3 step aider gets you the most height out of a climbing aider. Any more steps on the aider and you simply wouldn't be able to attach the aider to your climbing stick. Keep the 3 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.
