•Tru-Arc+ Cams
The Tru-Arc+ is a very unique cam system. It is technically a Hybrid Cam because it is
a blend of a Dual Cam system and a Single Cam system. It has the straight and level nock
travel of a Dual Cam and the timing simplicity of Single Cams. It is a very simple system to
set up and it is very easy to shoot. See the following guide for complete set up and tuning
of the Tru-Arc+ System

•Changing The Tru-Arc+ Draw Length
Your Tru-Arc+ uses two different cam
sizes to cover the full range of draw
lengths. Each cam covers four inches of
draw in half inch increments. Both cams
use the same module. Refer to your dealer
or www.martinarchery.com to find out what
module position gets which draw length on
your cam. Your dealer can exchange cams
if needed to attain your draw length.
To move the modules, you will need
to remove or loosen the mod screws and
rotate the mod to the proper letter. Higher
letters give the longer draw lengths.
TIP: Both modules need to be in the
same setting.
