Here for it....... have a nock high tear I'm struggling to get out

 

with a single cam, you have no opposing cam profile to compensate for nock travel. the nock can only do what the single profile directs it to do. it can be somewhat minimized by having the single cam in it's "sweet spot", but there will always be some vertical travel either at the beginning of thrust phase or at the end, just as the arrow leaves the string.

 

If that's the case, you are fairly limited to moving nocking point or moving rest

 

if by "limited" ,you mean "that is all you can do" then yes....no matter were you set the nock or the rest that vertical travel will be there. it is the reason twin cams made a reappearance and are again the status quo,....just as they were before single cams appeared. essentially there is no adjustment to vertical nock travel with a single cam. put the cam in it's sweet spot and you get what you get. the reason Mathews made the single cam big is because they designed a profile that had absolute minimum vertical travel by sculpting the string track to work against the cam profile to even things out as much as possible.

 

Thanks for the replies. My son shoots a pse stinger max(single cam). I'm putting a new arrow rest on for him. He's currently a bit nock high at brace. Just didn't know if i could set arrow dead level through Berger hole and adjust any high/ low by tweaking the vacuum position.

 

If you are setting the d-loop nock high at brace,
this might be a GOOD thing for a single cam. Shoot some arrows, and THEN decide if the d-loop needs to go further up or down.

Play with the buss cable, by pressing the bow in a bow press, and experiment with adding twists to the buss cable
and see if groups improve. If not, go the other direction, and try removing twists from the buss cable, and see if groups improve.
