Rough Draft. I put the Pinnacle Pulley System together by myself today by trial and error in my backyard pool. I took these pictures to help others put their’s together even more easily. I will take it apart and take it down to Cal Baptist University in my van. Pretty transportable as you can see. The base is the challenge because it comes glued I about a 4 and a half foot square. I’ll make a movie showing how to construct it and how to use it. We’ll use the EyeCart and Bottoms up to video how the swimmer’s stroke responds to what we believe is the most specific and progressive in-water stress possible. We’ll also edit these photos and movies. Want to buy one? Click Here. They start at only $2100 with everything, even a DVD of how to best use it, showing age groupers, Olympians, masters, and triathletes and even just some fitness swimmers. What a great invention!
