Ya its diferant than any other setup I' ve seen you can adjust the draw with out effecting cam tuneing . It is slightly diferant than dartons cps system when you change the draw the timing marks are not effected on the hoyt , if you change the draw on a darton it changes the index marks and cam index slightly . If you see one you will see what I mean . There are two modules that you change position on on the cam 1/2 and those modules dont even touch the string or cabels when the bow is at rest .
