Both fixed and mechanical broadheads kill deer. The difference is how they fail and what your setup needs. Fixed blades are tougher and penetrate better. Mechanicals fly more like field points and cut bigger holes. Here's what independent testing shows and how to choose.
I shoot 70 pounds, and I haven't confirmed my broadhead model for this page, so nothing below is a first-hand review. It's researched, with sources at the end.
Fixed vs mechanical at a glance
| Fixed blade | Mechanical | |
|---|---|---|
| Durability | More durable | More likely to break on bone |
| Penetration | Better | Less, varies by design |
| Accuracy | Needs a well-tuned bow | Easier to shoot accurately |
| Cutting diameter | Smaller | Larger |
Summary of Outdoor Life's broadhead FAQ by Scott Einsmann.
What the tests found
- Outdoor Life (Scott Einsmann). Tested 23 fixed and mechanical heads in 2023 and nine new mechanicals in 2026 for sharpness, accuracy, durability and wound channel. His summary of the trade-off: the Iron Will S100 penetrated better than any head but had a relatively small wound channel, while the SEVR cut a big hole.
- Field & Stream. Over two years and 33 models, its tester found only 40 percent of all heads survived a cattle-rib test unscathed, and only 9 percent of mechanicals did. His conclusion is that fixed blades are better. He also notes some hunters cite data showing higher recovery rates with mechanicals.
A simple rule for choosing
Outdoor Life's Einsmann puts it this way:
- Over 50 pounds, about a 450-grain arrow, and not confident in your tuning: shoot a quality mechanical.
- Under 50 pounds or shooting a recurve: shoot a fixed head. Easton gives the same advice for low-poundage setups, recommending a sharp 3-blade fixed head.
- Over 50 pounds and you can tune a bow: shoot whatever you like.
Outdoor Life's tuning test: if your bow shoots a bare shaft with your fletched arrows at 20 yards, you can shoot most fixed blades accurately.
Four heads, budget to premium
Outdoor Life's 2026 deer picks, with prices checked October 10, 2026. Prices are approximate.
| Head | Type | OL pick | Approx. price |
|---|---|---|---|
| Magnus Black Hornet | Fixed | Best Budget | $51.99 for 3 (maker, 4-blade) |
| Rage Black Series | Mechanical, 2" cut | Best Value Mechanical | $39.99 for 3 (maker) |
| SEVR Magneto Ti 1.75 | Mechanical, 1.75" cut | Best Mechanical | $87.96 for 4 (Amazon) |
| Iron Will S100 | Fixed | Best Penetration | $139.95 for 3 (maker) |
Maker notes:
- Magnus lists a .059" main blade, user-sharpenable blades and a lifetime guarantee.
- Rage lists a 2"+ cut, .035" blades and Shock Collar blade lock.
- SEVR lists magnetic blade retention, a Grade-5 titanium ferrule, 100 and 125 grain options, and vertical bows only.
- Iron Will lists a .062" A2 steel main blade, a 1 1/16" main cut and grains from 100 to 250.
What you give up going cheap
Price alone doesn't decide it here. Outdoor Life's budget and value picks made its deer list, so a cheap head can be a good head. The bigger risk is durability: per Field & Stream's rib test, many mechanicals need new blades or replacement after hitting bone.
What more money buys
In Outdoor Life's testing, the premium Iron Will S100 penetrated better than any other head, and the SEVR cut a big hole. Whether that matters depends on your setup and shots.
Before the season
- Check your state's rules. Rules change. Idaho, for example, didn't allow mechanical broadheads for big game until a 2022 law allowed them during archery seasons.
- Verify your sight with broadheads. Outdoor Life's Alex Robinson says to verify every yardage with your hunting arrow and broadhead.
- Draw weight matters. See draw weight for deer for energy numbers.
Other good options
- Single bevel. Outdoor Life named the Cutthroat S7 best single bevel.
- Hybrids and big-cut mechanicals. Outdoor Life's lists also name a best hybrid and a best head for large wound channels. See its pages in Sources.
Questions hunters ask
Fixed or mechanical from a saddle? Field & Stream's tester argues fixed blades handle shots that hit bone better, which matters on quartering shots. See saddle shot angles.
Do mechanicals fly better? Outdoor Life says they're easier to shoot accurately.
What grain should I use? Match the head to your arrow setup and spine. A bow tech can help.
