I got my anti cant device from preda8or today. He did a fine job of drilling a scope ring and mounting a bubble level in the hole. I think it will work well and was originally worried about the ruggedness of the device. It is of better quality than some of the other scope levels on the market I have seen mounted. I am planning on coyote hunting this weekend and will try it out then (weather permitting). I would definately order from him again in the future.
