Archery term
Cam
What does Cam mean?
A cam is the rotating, often elliptical wheel mounted at the end of a compound bow's limb that the string and cables run over. The shape and timing of the cam system define the bow's draw cycle, including how draw weight builds and where let-off occurs.

Why it matters
The cam system is what gives a compound bow its mechanical advantage, its draw-force curve, and its let-off, distinguishing single-cam, hybrid, and dual-cam designs. Cam timing and synchronization are central to how smoothly a compound draws and how well it tunes, making the cam a defining component of compound bow performance.
What to check
- Check the bow maker’s setup and maintenance instructions for the exact cam system.
- Cam timing, module changes, and cable work belong with a qualified technician.
- Compare complete compound bows only when the model and category are confirmed.
