JNJ I have just got a sentinel. Rohen dont know what u got with teh bow but the user guide as came with the bow is as useful as a bull with an udder. On the DL section they only describe the cam module adj no mention of AS WELL adjust post.
JNJ go to the
Bowtech
website, in downloads you will find a page with 2 tables the top table refers to the module setting for each particular DL say 26.5" is no. 5 set the top and bottom module to this no. Then got to the bottom table , this gives you the hole into which the post must be screwed for your particular DL I am a leftie so my hole count may be opposite direction to yours (the holes are not numbered so where do u start from??). You will not that the post has a slotted hole this is to adjust the let-off. Adjust it so that it hits the cable early means that it it has only come down a small amount on the back curve of the force/draw curve therefore low let-off
