Acu-Trak and Tranz Single Cam
Martin Single Cam systems feature a modular draw length adjustment. A series of draw
length modules are used to adjust draw length in one-inch increments (see below). Draw
lengths can also be adjusted in half-inch increments within each size module.

Adjusting The Single Cam Draw Length
Using draw length modules, the draw length can be adjusted in 1" increments. 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 module sizes range from F-1 to F-7. As the module numbers get higher, the draw gets lon-
ger. The draw length can also be adjusted in 1/2" increments using the pegs on the back of the cam.
This method of draw adjustment applies to ALL Martin Single Cam System (Fuzion, Dyna,
M-Pro, and M2).
