I used my EONPOW's a few times last year with my mods and even shot a couple deer while using them. I loved @Boudreaux's screw method so I added that in. My first crack at adding the screws didn't work when I tried putting the nuts on with JB weld and it broke on the left climber the first time I hunted with them. It was 6am and cold and I had to get creative to climb the tree so I made a makeshift aider out of my tether and climbed with the right climber. That was the morning I shot my buck! With that in my head here is a photo of what I came up with. Cuts the weight of the system in about half and its at least almost as easy, if not as easy to climb as with 2 of the climbers. Plus eliminating one of the climbers cuts down on the noise potential. All it is the red squirrel aider for my left foot and the EONPOW climber on the right. I have incorportated the metolius easy aider foot portion onto my aider. I did the screw mod plus added a bungee for the back of the foot and a cam buckle with rubber tubing for the top of the foot on the climber. This will most likely be my mobile method for places I can't use spurs next year which is about 1/2 of my hunting. Maybe I'll even get a video up in the near future .
