My friend that helps me crossbow hunt normally use a cranking type cocking device. This works great for us, but it is noisy and takes longer to cock.
My Mr. Macho son, is extremely strong and very capable of easily pulling back my 175 pound Carbon Express crossbow. Whenever we did a lot of practice shooting, we would let him manually cock the crossbow, although he did complain of some back discomfort after an evening of shooting longer than normal.
Until the day the string slipped out of his hand nearly causing a full blow dry fire, not to mention he could have lost a finger or two. Ever since, I SAID NO MORE. It is simply too risky and not worth taking a chance. I looked at the major brand pull rope cockers and they were (in my opinion) completely overpriced.
Then I found this universal rope cocking device at an affordable price. Mr. Macho adjusted the rope to the desired length. It is easy to attach, smooth, quite, easier to use than the wench type cocker, and reduces the amount of pull weight. He no longer complains of his back hurting. This cocking device has been very helpful and made practice SAFER and easier on everyone involved.
Simply grasp the hooks and drape the rope over the groove of the stock and place the hooks onto the crossbow string on each side of the flight track. Once this is accomplished, simply hold the crossbow by stepping on the foot stirrup and pull the crossbow string with the molded T handles back until the trigger mechanism locks.
