How to Choose a Compound Bow And Why We Will Not Rank Them

Published October 2026A chooser, not a rankingBrand specs verified Oct 2026

Every compound bow in America is sold on a speed number named after an organization that does not publish it. We went looking for the IBO standard. The IBO has no bow-rating standard — its rulebook is a 3-D tournament rulebook. The one real consensus standard that did exist, ASTM F1544, is marked "Standard Withdrawn, No replacement." And one major manufacturer states on the record that the method everyone else uses fixes no draw length at all and allows up to about 82 pounds. So we are not ranking compound bows, and this page is the argument for why.

"IBO Speed" Is Not a Standard. We Went and Looked.

Open any compound bow's product page and you will find a number: 335 fps, 340 fps, 348 fps. It is almost always labeled "IBO." The universally repeated understanding is that IBO means a 30-inch draw, 70 pounds, and a 350-grain arrow.

We went to find the document that says that. Here is what is actually there.

The IBO does not publish a bow-rating standard

We read the International Bowhunting Organization's actual rulebook. It is a 3-D tournament rulebook. It contains competition limits — Pro and Semi-Pro classes "limited to a 300 fps arrow speed," Youth Hunter 260 fps, crossbows 350 fps, with "All maximum speed limits are allowed a 3% variance for chronograph accuracy." And it contains an arrow-weight floor for competitors: "Arrows must weigh at least five (5) grains per pound of the bow's maximum shooting weight."

It contains no test procedure, no test conditions, no rating method and no 30-inch draw length. The IBO's own description of itself is a body that promotes bowhunting and runs 3-D events. Speed ratings and manufacturer certification are not mentioned.

The one real standard was withdrawn this year

ASTM F1544, Standard Specification for Determining the Rating Velocities of a Compound Archery Bow, is the only formal consensus standard we found. Its scope says it "will provide only a certification of performance, that is, the velocities at which a given bow will launch arrows of specified weights under standard conditions."

Its status, as published: "Standard Withdrawn, No replacement." Last updated January 15, 2026. The full text sits behind a $77 paywall whose purchase block reads "out of stock," so we could not read the conditions it specified and we are not going to guess at them. The only document that ever promised a certification of performance no longer exists.

The Archery Trade Association does maintain technical guidelines. They are behind a member login. The public page lists the companies that contributed and no specifications at all.

Then a manufacturer said it out loud

This is the part we did not expect. Hoyt's own 2025 hunting whitepaper describes the method its competitors use, in print, on its own site:

"Unlike other companies, Hoyt tests to ATA speed guidelines." Hoyt gives the ATA conditions as a 350-grain arrow, 70 pounds, and a "Draw length of 30”, +/- 1/4”."

And it gives the IBO conditions as "Draw weight up to 80lbs +/- 2 lbs" and — the line that matters — "No specified draw length standard." Hoyt adds: "By testing up to 82lbs, efficiencies can be found."

Nobody audits any of it. We found no conformance clause, no certification mark and no verifying body in any obtainable document. Every speed figure on every compound bow page is self-reported.

Bows Are Advertised at Speeds Their Own Spec Sheets Cannot Produce

This is where it stops being a technicality. If the test condition is a 30-inch draw, then a bow that cannot be set to 30 inches cannot produce its own advertised number in anyone's hands.

The Prime Divide, 31-inch axle-to-axle model: "IBO Speed" of 335 fps, published draw-length range 25.5 to 29.5 inches. The bow does not reach the test condition.

And Hoyt is the only brand we found that prints the problem instead of hiding it. Its whitepaper states that the RX-9 SD and Alpha AX-2 SD do not reach draw lengths of 30 inches, and rates them instead at "their max draw length of 27 inches and 70 pounds with a 350 grain arrow." That is a manufacturer publishing a lower number because the higher one would be fiction. It is the single most honest thing in this category.

One brand of nine names a standard and states its conditions. Darton is the only one calling its figure "ACTUAL," implying a measurement, while disclosing no conditions at all. PSE is absent because its product pages blocked automated access and we will not take specs from a retailer.

Why We Will Not Rank Compound Bows

We rank almost everything on this site. We score trail cameras, broadheads, boots, harnesses, knives and crossbows on five weighted pillars and we publish the numbers. We are not doing it here, and the reason is not that the category is hard. It is that a ranked list would be the exact kind of content this site exists to criticize.

The same bow is a different bow at a different draw length

A compound is fitted. Its draw length is set to you, and its performance, its feel at full draw and its forgiveness all change with that setting. And the stated setting is not comparable between brands. Darron McDougal, who has worked an archery counter, puts it directly: "So many variables affect draw length." Bows from different brands at the same nominal setting do not draw the same. He describes a customer who "insisted that his draw length was 30 inches" and could barely reach it.

So the number on the spec sheet is not a thing you can compare across manufacturers. That is the same finding as the speed section, arrived at from the other end.

Nobody publishes the one distribution that would make the test condition meaningful

If the industry tests at 30 inches, the obvious question is how many hunters draw 30 inches. We could not find a published draw-length distribution from any manufacturer, from the ATA, or from the IBO. No bow-shop dataset, no sales breakdown, nothing citable. The figures that circulate are forum arithmetic.

And there is no manufacturer rule of thumb for what a shorter draw costs you. The familiar "about 10 fps per inch" and "about 2 fps per pound" appear in blogs and forum posts and in no manufacturer document, no ATA page and no IBO rule we could reach. We are not printing a number we cannot source.

The honest version needs no missing data, because the manufacturers supply it themselves: five of the nine bows above bottom out at 25 or 26 inches, and two flagship families top out below the test condition entirely. The test is run at or past the ceiling of the range the category actually builds for.

One measured data point, clearly labeled

Writing in Shooting Sports Retailer in August 2026, Joe Bell chronographed a Mathews Lift-X rated "(348 fps IBO)." His result, in his words: "When I reduce the draw weight on the Lift-X from 65 to 55 pounds, it drops the arrow speed to 270 fps."

That is one reviewer's chronograph, at a weight below the test condition, and we are presenting it as an illustration and not as a specification. Three hundred and forty-eight advertised, two hundred and seventy measured. The gap is the distance between a test condition and a hunter.

And the hunters worked it out independently

On Rokslide, in a thread about understanding IBO, hunters describe the figure as measured at roughly 82 pounds with nothing on the string, and one notes it is "really just 5grs per pound" — a rule of thumb and not a measurement. That matches Hoyt's published description of the IBO method almost exactly, and neither is quoting the other. A manufacturer disclosed it in a whitepaper footnote and owners reverse-engineered it from the outside.

We will print the dissent too, because it is real: in the same discussions, some hunters say speed is "the biggest selling point" and shop on it deliberately. Claiming nobody cares about the number would be its own overclaim.

What a Pro Shop Owes You, and What It Means When One Will Not

If we are not giving you a ranked list, we owe you something more useful. Here it is, and it is not our opinion.

The Archery Trade Association certifies bow technicians, and it publishes the skills its compound program grades them on. That published curriculum is, in effect, a list of what a competent shop does. Verbatim, the compound program covers:

• "Compound bow parts & function"
• "Foundational form & bow fitment"
• "Draw length & weight fitting"
• "String & cable replacement, cam timing"
• "Axle-to-axle & brace height adjustment"
• "Rest, peep & d-loop installation"
• "2nd & 3rd axis sight leveling"
• "Arrow selection" and "Basic paper tuning"

In the hands-on practical assessment, graded "under the supervision of a qualified instructor who will use a scoring rubric," the candidate must "Adjust draw length & weight based on form fundamentals." The course costs $600 and the assessment is a half day in person.

On time: a trade-press account of a correct setup puts it at "up to two hours" for most technicians, covering paper tuning, setting draw length, and setting peep height for the individual shooter. Two hours is a usable yardstick. A bow handed over the counter in fifteen minutes did not get the work.

Two honest limits on that, which we are printing because they matter

• The ATA's pages name no equipment. Neither the certification page nor the program announcement mentions a bow press, a draw board or a chronograph. We are not going to tell you the ATA requires tools it never lists.
• There is no public directory, and this is the real problem. We found no consumer lookup and no registry of certified technicians. A hunter cannot verify a shop's ATA certification online. You have to ask the shop and take the answer, or email the association. The ATA's genuinely useful material — the technical guidelines, the certification records — consistently faces the trade and not the buyer.

Draw Length: The One Place a Real Standard Exists, and It Measures the Bow

There is an ATA Standard Draw Length, and it is worth understanding precisely what it governs. Per Hoyt's glossary, it was established "to provide an industry standard of draw length and eliminate the variances in the original method caused by different thicknesses of bow risers," and it is arrived at by measuring to the pivot point of the grip and "adding 1 and 3/4 inches." Manufacturers use it to designate a bow's draw length.

The wingspan shortcut, and what it is actually worth

Stand in a T, measure fingertip to fingertip, divide by 2.5. Archery360, which is the ATA's consumer-facing site, does endorse this — as a "great starting point" that you then confirm by shooting. Trade press puts the same bounds on it: the estimate is "good to about half an inch."

So no authority endorses wingspan division as a fitting method. The ATA's own consumer arm calls it an estimate with a half-inch error band that has to be checked at full draw. On forums it circulates without the caveat, stated flatly as the answer. Half an inch is enough to matter.

What too long and too short actually look like

The clearest authority statement we found is from North American Whitetail. Too long: "If the bow arm drops or swings to the side, the draw length is probably too long." It "raises the bow shoulder and places the forearm in line with the string" — which is why the question "Is the string hitting the bow arm when the arrow is shot?" is diagnostic. Its verdict: "Successful results are very difficult and unlikely when the draw length is too long."

Too short: you feel "bunched up or uncomfortable because you are too compressed," and "the elbow will have a fairly big bend in it in order for you to get the string to your face."

Hunters on the forums independently report the same two symptoms — forearm contact with the string, and the collapsing bow elbow. Where they diverge is the fix: forums offer anchor rules of thumb, like the string touching the tip of your nose. The authority source works from the position of the scapula and from what the bow arm does after the shot. Both are on this page, labeled, because the symptoms agree and the methods do not.

One useful detail from the same source: a hunting draw length is often set about an inch shorter than a target draw length, because string contact with clothing produces "an erratic flight path from your arrow."

What we could not get: peer-reviewed biomechanics. The one relevant paper sat behind a CAPTCHA. So the injury argument on this page rests on the ATA's consumer site and on hunters' own accounts, and not on a study. We are saying so instead of implying more.

Draw Weight: The One Question Where the Community Is Nearly Unanimous

We ask every category what hunters actually do, as opposed to what the marketing says. On compound draw weight the answer came back clearer than almost any finding on this site.

Seven-plus hunters, across two forums, all describing their own bows, run well under 70 pounds for whitetails — and nearly every one of them came down from heavier. Nobody reported going back up.

• One hunter who had "always kept my compound bow cranked up to 70lbs" describes feeling the joint "shift around inside" when drawing.
• Another: "last fall I had to drop my bow to 55 pounds by the end of September."
• Another had a shop turn his bow down to 60.
• One running 60 pounds reports killing an elk at 62 yards with it. Another: "Last 3 bulls I've arrowed have been with a 55 pound draw."
• On whitetails specifically: "I've been hunting whitetails with 60 lb draw weight for 23 years." "I shoot 50 pounds with roughly a 326 grain arrow." "The low 50s is all you need if you have a heavy arrow." And bluntly: "Absolutely no reason to shoot 72 on a whitetail."

The dissent, printed because it exists: at least one hunter rejects the whole premise — "I'm not decreasing my odds with a lower weight."

On why hunters came down, we are going to be careful. The accounts include shoulder trouble, a rotator cuff tear, and a bicep injury — and the causes given include a motorcycle accident and surgery, not just archery. So we are not claiming a bow caused anyone's injury. What the reports support is narrower and more useful: hunters who develop shoulder trouble reduce poundage and keep killing animals. Sixty pounds took an elk at 62 yards. Fifty-five took three bulls.

The Real Reason to Buy From a Shop Is the Warranty, and It Is Narrower Than the Phrase

We expected to find manufacturers arguing against buying online. We did not find a single position statement. What we found instead is warranty architecture that accomplishes the same thing without anyone having to say it.

Mathews calls its coverage a Limited Lifetime Warranty. The terms, verbatim:

• It runs "only to the Original Registered Owner," and "Warranty claims made by someone other than the Original Registered Owner will not be covered under this warranty."
• It applies to bows "purchased at an Authorized Retailer."
• Bows "must be registered within three (3) months of purchasing," and Mathews "reserve[s] the right to deny warranty claims" for bows that were not.
• "You must process a warranty claim through an Authorized Retailer," and "Authorized Retailers may charge for service work that accompanies warranty fulfillment."
• "Any alterations to the bow, including cosmetic refinishing, voids any and all warranties, written or implied."
• Excluded: normal wear, dry fires, cosmetic damage, and consumables including strings, cables and dampers — which are the parts on a compound that actually wear out.

We checked Hoyt as a comparison and got one line — "You must register your Hoyt bow's serial number in order to have warranty work performed" — before the full document blocked us. We are not assuming Hoyt's terms mirror Mathews'. Read yours.

What to Actually Do

1. Decide your draw weight before you walk in

For whitetails, the hunters who have done this longest converge on 50 to 65 pounds. Pick your number, then buy a bow whose range tops out near it instead of detuning a heavier bow.

2. Get measured, then get watched

Wingspan over 2.5 gets you within about half an inch. That is a starting point and not an answer. The rest is someone competent watching what your bow arm does when the shot breaks.

3. Ask for three things by name

Draw length and weight fitted to your form. Paper tuning. Peep height set for you. Those are on the ATA's own technician rubric, and asking for them by name tells you a great deal about the shop before you spend anything.

4. Shoot more than one brand

The same stated draw length does not feel the same across manufacturers. This is the one claim in this guide that comes from people who sell bows, people who shoot them, and the physics of the thing all at once.

5. Ignore the speed number

It is self-reported, measured to no published standard, at a draw length the method does not specify, possibly at 82 pounds, and on several bows at a setting the bow cannot reach. A 300 fps bow and a 340 fps bow will both kill a deer at 30 yards, and neither will do what the box says in your hands.

6. Register it within ninety days

Set a reminder the day you buy it. On at least one major brand, missing that window is grounds to deny every future claim.

Methodology Notes

The full method, what we own, our independence policy and how AI is used: How We Test →

This is a chooser and not a ranking, and it carries no Gear IQ scores and no buy links. We publish choosers where a ranked list would mislead — we have done it for trail cameras, broadheads and hard blinds. Compounds qualify because the product is fitted and the headline spec is not comparable between brands. Scoring them 1 to 100 would lend a false precision to exactly the numbers this page is arguing against.

Every specification, warranty term and claim here came from the manufacturer's own page, the ATA, the IBO's own rulebook, or named trade press, in October 2026. Where a brand publishes nothing, this page says so.

What we could not get, and it shapes what this page can claim. ASTM F1544's full text — withdrawn and paywalled at $77, with the purchase block showing out of stock, so we report its withdrawal and not its contents. The ATA's 2025 Technical Guidelines — behind a member login. PSE's product pages — blocked automated access on two separate URLs, and we will not take specifications from a retailer. Peer-reviewed archery biomechanics — the relevant paper sat behind a CAPTCHA, which is why the injury discussion above is sourced to the ATA's consumer site and to hunters' own accounts and labeled as such. Hoyt's full warranty PDF — blocked, so we did not assume its terms match Mathews'. And a trade article specifically on fitting a customer to a bow, which would have told us what equipment a fitting requires.

On the Hoyt whitepaper, which does a lot of work on this page: it is a marketing document from a company that benefits from the comparison it draws. We are using it because it makes a specific, checkable, factual claim about a competitor's test method, and because the IBO's own public rulebook independently supports the key part of it — there is no draw length in that document. We would not run the claim on the whitepaper alone.

On community sentiment. We reached Rokslide, Hunt Talk and the Bowhunting.com forums. ArcheryTalk blocked automated access again — it loaded for one of our researchers and refused two others on the same day, so we have stopped asserting whether it is blocked and simply report what happened. GON never surfaced in search for these topics and was not reached. Rokslide strips usernames from many reply bodies, so some quotations above are corroboration we could not attribute to a named poster, and we have not presented those as individual accounts.

One thing we deliberately did not write. We went looking for a pattern of hunters moving from compounds to crossbows because of shoulder trouble. We found nothing we could source — not one post in anything we reached described it. It is very likely a real pattern, and the forums where that conversation lives are among the ones that block us. So it is not on this page. We would rather leave an obvious gap than fill it with something we assumed.

Brand web presences, a standing check here. Diamond Archery runs a sitewide fraud warning naming diamondarcheryusa.com as a fraudulent site that has taken money from multiple people, stating that "the only website we operate from is https://diamondarchery.com." That is a manufacturer-confirmed fake, and it is the latest in a run of these we have found across hunting gear — gambling redirects, a casino affiliate page, an affiliate shell posing as an official site, a domain-resale listing. Also: Bowtech runs a publicly search-indexed staging server whose product pages appear in results alongside production ones. Specifications there may be stale and we did not cite it.

And a corporate relationship worth disclosing, because we treat these brands as separate choices. Bowtech, Diamond and Excalibur are one company — Pure Archery Group. Excalibur appears in our crossbow guide and Bowtech and Diamond appear in the table above. That is the second time in two days that products we presented as independent turned out to share an owner, and we have added "who owns whom" to the checks we run before publishing a field.

Research and drafting on this site are AI-assisted. The Gear IQ Method, the scoring weights and the final rankings are ours, and every guide is reviewed and approved before it publishes. How we work →

Flagged for the next pass: whether ASTM F1544 is ever replaced, whether any brand besides Hoyt begins naming its speed standard and conditions, whether the ATA publishes a consumer-facing directory of certified technicians, and PSE's specifications.
