After 4 major surgeries the past year due to cancer, I have lost the strength in my arms and shoulders to the point that I can no longer cock my Excalibur Exomax crossbow. Therefore I'm in dire need of the Krankaroo mechanical cocker designed for this particular bow. Excalibur says this is the only device that will work and there are no substitutes and they no longer make nor stock any of them. They did not seem at all interested in trying to help me locate one either. Does anyone on this forum know of one anywhere for sale? Just 4 weeks until opening day of archery season, so time is of the essence. Any and all help will be greatly appreciated. Thank you.
