Two points here:
1. I've read all the science about what deer can and can't see. I've read about why camo works and why some patterns are better than others. Science says they shouldn't be able to see my sticks and aiders, but I'll be damned if I haven't watched multiple deer walking along, spot my stick/aider and follow it up the tree to me. I've seen it happen to a lot of other self-filmers as well. Guys have talked about it on this forum a lot. I've seen it happen with no wind blowing the aider as well. That said, it didn't mean the deer spooked - some did, some didn't. And I've had way more deer walk by the sticks/aiders and pay them no attention. But I don't like any of them knowing I'm there at all. I don't pretend to know the answer. The only thing I can control is my effort to reduce the chances of this happening. If some spray paint camo, and DIY camo aiders help me do that, I'm all for it. It may not help at all lol!
2. Bringing aiders up the tree. I can't go any less than a 4 step aider and still get over 20' high. I'd have to carry a 4th stick and I don't want to do this. I haven't come up with a good method for attaching a 4 step aider to my Muddy stick while being able to carry it up the tree with me. I suppose I could sling it over the bottom step. I just haven't tried it yet. I assume reaching down below my feet to attach/detach the aider and move it up/down to the next step would be troublesome. Maybe not? Maybe I just need to do more yoga. What I've started doing is rolling up the aider and placing it on the top step during the hunt. While standing on the bottom step, I squat down a few inches and hook the aider with the toe of my boot. I grab the aider off my boot, wad it up, and lay it on top of the stick. When it's time to descend I simply drop it back down. I've done this method twice now and it worked very well.
