You measure from the nock point on the string to the berger hole (the hole your rest screws into) and add 1 3/4 inches. that gives you the AMO draw length.

Measure from the spot where the nock touches the bowstring,
when the bow is at full draw....

and measure to the pivot point of the grip area
(this is the deepest part of the curve on the grip area).

Sometimes, but not always,
the arrow rest hole (closest to your face)
will kinda sorta line up with the deepest part of the curve on your grip.


If you take your grip off,
then this changes the bow draw length setting.

If you put on a custom grip that is thicker,
then this changes the bow draw length setting.








So,
hold your bow at full draw,
and have a friend help you with getting a tape measure measurement
between nock groove (where it touches the bowstring)
all the way to the grip area (guess-ti-mate where your skin touches the curve on the grip....it's about where the bottom of the thumb joint is located).


Write down the tape measure measurement,
and then add 1.75-inches to the number on the piece of paper...

that's the draw length setting of the bow.


So, if you have a 28-inch cam,
the tape measure should read 26.25-inches.

If you have a 29-inch cam,
then the tape measure should read 27.25-inches.


So,
if your Switchback has a 29-inch cam,
and the tape measure reads 28-inches....instead of the tape measure reading 27.25-inches....

this means...

a) bowstring does not have enough twists, so the bowstring is not at the factory recommended length
(this results in the tape measure reading more than it should)

and/or

b) the cable has too many twists in it, so the cable is too short
(this means the ATA is shorter than factory spec)
(when the ATA is shorter than factory spec, then the tape measure will read longer than the factory spec)
(...tape measure should read 27.25-inches for a 29-inch cam...)

and/or

you too off the Mathews grip and are shooting directly off the riser?
