•Adjusting The Dyna Cam Draw Length
Using draw length modules, the draw length can be
adjusted in 1" increments. The modules can also be used
to adjust the let-off. A high let-off module is marked as
"F". A 65% let off module is marked with a "F/". The slash
on the end of the size number indicates 65% let-off. To
change the draw length, replace the module on the cam
by removing the screws that hold it to the cam.
NOTE: do not draw your bow without the module
installed. It will damage your harness.
The Dyna module sizes range from F-1 to F-7. As the
module numbers get higher, the draw gets longer. The
draw length can also be adjusted in 1/2" increments
using the pegs on the back of the cam. The #2 peg is the
prescribed draw length for each module. The #1 peg is
1/2" longer and the #3 peg is 1/2" shorter.
