I can see this device being useful to see how one's position is. It tells you whether you are on center and how your legs and reins are. However, it isn't practical to have one at home because the price is somewhere in the 30-70k range. I'd hop on one if I had the chance, but I wouldn't buy one. What do you think?
I want to ride it to know if it's me, my horse, or both us off off balance lately! I think it would be an interesting diagnostic tool, but I wonder how it compensates for the real movement of a horse. I know my horse is a fairly straight traveler but not that smooth and straight!
