I'm presently shooting a Cooper John Pro11 on my Max 3000. I've been looking at there Pro111 w/3rd axis. I can't seem to find any info about the set-up. Anyone know where I can down load set-up instrustions? Also explain the advangaes and purpose of the 3rd axis? If I'm not mistaken is it suppose to eliminate any yardage ajustments for up and down shots? Does it really work? Jerry
