I met Andrew and JNDEER at Redding this year. I sat through their presentation and have to admit, they made 3rd axis so much easier to understand. The watter bottle that bowhnter7 mentioned above is the perfect visual display to illustrate it. I also let Andrew adjust my 3rd axis while there and walked away with one of their Easy Leveler. The rest Hamskea has, that Aron is using on his bow, is also a bullet proof rest. It can attach to either limb, the cable or shoot it as a lizard tongue set up. Pretty nice in every aspect. Hamskea is making tuning the 3rd axis super simple with their leveler. Gone are the days of shooting it in at 60 yards on a severe downslope. That process usually took me an hour or more. Thanks Hamskea....
