How to choose between fixed and mechanical broadheads for whitetail — flight, penetration, blood trails and our picks.
No archery topic starts more campfire arguments. The truth: both designs kill deer reliably when matched to the right setup — and chosen for the right reasons.
Fixed Blade: The Reliability Pick
No moving parts, full energy into penetration, bone-tolerant. The cost: fixed blades expose flaws in your tune, so paper tune and re-zero before season. Best for lower poundage setups and anyone who values mechanical certainty.
Mechanical: The Accuracy Pick
Field-point flight and wider cutting diameters mean bigger blood trails from well-placed shots. The cost: energy spent opening blades and more parts that can fail. Best from fast compounds at 60+ lbs.
Our Rule of Thumb
- Under 55 lbs draw weight or any doubt about tune → fixed blade.
- Fast, well-tuned compound and broadside shot discipline → mechanical earns its blood trails.
- Either way: verify kinetic energy with our KE Calculator.
Frequently Asked Questions
Do mechanical broadheads fail often?
Modern designs are reliable, but every failure mode (blades opening in flight, deflection on angled bone) is one a fixed blade structurally cannot have.
What grain broadhead should I shoot?
Match your field point weight — 100 grains is standard — so practice and hunting arrows fly identically.
