RE: what dose this do?? "bowtech
Not only does it adjust letoff , and valley , but drawlenght , all at the same time . If you lessen one you lessen them all , and visa/versa unfourtanatly . They advertise drawlenth and letoff adjustable , but with the bowtechs of years past you could not adjust those things independantly . This year they came out with adjustable draw force modules , an improvement for those of us who want adjustability .
