What Is Compound Crossbow?

Compound Crossbow: A crossbow that uses cams and cables on the limbs to store and release energy.

By Marisol Vega, Senior Outdoor Equipment Writer & Research Editor. Manufacturer figures vary; check your crossbow's manual.

Compound crossbows add cams and cables to the limb tips. This lets a crossbow store more energy over a given power stroke and, in many designs, reduces the force needed at full draw.

The added components mean more parts to maintain; follow the manufacturer’s maintenance schedule and have limb or cam work done by qualified technicians where required.

Why Compound Crossbow matters

Compound crossbows use cams and cables to store more energy in a given power stroke and to reduce the force felt at full draw. That is why most high-speed hunting crossbows are compounds.

The additional parts mean more maintenance. Strings and cables wear and need attention on the schedule the manufacturer specifies.

How to read it on a spec sheet

  • Look at cam design and let-off, where quoted, along with draw weight and power stroke.
  • Check the maintenance requirements and who is allowed to service cams and limbs.
  • Compare the cocking method: many compound crossbows include a cocking aid or crank.

Common mistakes

  • Attempting cam or cable adjustments without proper equipment and instructions.
  • Overlooking string and cable inspection.

Frequently asked questions

What is the difference between compound and recurve crossbows?

Compounds add cams and cables, improving efficiency and often speed; recurves are simpler with fewer parts. See our compound vs recurve guide for a full comparison.

Do compound crossbows need a bow press?

Some service tasks may. Follow the manufacturer’s guidance and use a qualified technician where required.

Are compound crossbows louder?

Not necessarily. Noise depends on the specific design and damping.
