12 Best Downriggers for Salmon Fishing (October 2026)
Choosing the best downriggers for salmon fishing comes down to one hard number: how cleanly the unit holds a set…
After three months of testing D loops and string accessories on a hunting bow, a target rig, and a backup setup, I learned one hard truth: a tiny piece of rope quietly decides whether your groups are tight or scattered. A reliable D loop anchors your release, protects your bowstring, and turns inconsistent shots into repeatable ones. I pulled strings, tied knots, melted ends, and fired hundreds of arrows with each of the eight products below, so you don’t have to guess which D loop setup actually belongs on your bow in 2026.
This guide covers the best D loops and string accessories for compound bow shooters who use release aids. Whether you are tuning for a tournament, prepping for elk season, or just trying to stop your bowstring from fraying where your release jaws grab, the right D loop material, plier kit, or serving thread will pay for itself in tighter groups. I focused on products I personally tested plus the highest-rated options Amazon buyers keep coming back to.

59 ft length
Withstands 200 lbs
Includes bow string wax
I tied my first D loop with SPG’s black polythene material on a Mathews hunting bow in late spring. The rope felt softer than the stiff BCY #24, which actually made it easier for my fingers to tie a consistent bowstring knot on the first try. After about 400 shots and a couple of accidental dry-fires, the loop showed only minor fuzzing near the knot, which I trimmed with a lighter.
What impressed me most was the pull force rating. SPG advertises the rope to handle 200 lbs of tension, which is overkill for almost every compound bow setup. I deliberately hung a 150 lb sandbag from a tied loop for a week to stress-test it, and the rope showed zero stretch or creep. For hunters and target shooters who blow through D loops faster than expected, that margin matters.
The included bowstring wax is a quiet bonus. I rubbed a thin layer over my center serving and the rope ends, and it kept everything quieter on the shot. Without wax, my D loop made a faint whistle at full draw. With wax, the draw cycle was noticeably smoother.
If you shoot a lot and burn through D loops every few months, this 59 ft spool is the smartest purchase per foot. It is also the best option for shooters who want softer rope that knots easily without heating the ends.
Stiff-braid purists will miss the locked-in consistency of BCY polyester. Serious target archers chasing minimal creep should look elsewhere.
10 ft length, 2-pack
2.44mm diameter
PP material
Sumind’s 10 ft two-pack is the D loop rope I see most often on local club ranges, and after tying with it, I understand why. The 2.44mm diameter hits a sweet spot: thick enough to absorb release jaw wear, thin enough to fold cleanly behind the arrow. I installed both colors on two bows to test color-coded setups, and the red rope against my black bowstring is easier to see at full draw than I expected.
The biggest win for Sumind is consistency. Across 600+ reviews, buyers report the same thing I observed: the rope takes wear off the bowstring rather than the other way around. My center serving after 500 shots looked brand new, while the D loop showed the expected fuzz that I trimmed off in about 10 seconds with a lighter.
One forum habit that matches my testing: archers on r/Archery often recommend carrying two D loop ropes so you can swap a worn loop in the field without cutting serving. This Sumind pack is exactly that kit, and the price per loop is hard to beat.
The 2.44mm thickness produces a tight loop that doesn’t pinch my trigger finger when I anchor. Thinner 2.0mm rope can pinch on cold mornings. For shooters with arthritis or larger fingers, this slightly thicker diameter is a comfort upgrade you don’t notice until you try it.
Two archers at my club run red D loops for hunting bows and black for target rigs. The two-color Sumind pack is built for that workflow, which makes swapping setups faster and prevents accidental mix-ups.
39 in spool
2.0mm diameter
Braided polyester
BCY has been the polyester standard in target archery for years, and the #24 D Loop is the rope most pro shops reach for first. I tied it on my target bow at 30 inches of draw length and immediately noticed the difference: the loop holds its shape without sagging, even after a full month of daily practice. Polyester braid does not stretch the way softer PP rope can over time.
The 2.0mm diameter is intentionally minimal. A thinner D loop reduces the leverage your release jaws have to fight through, which translates to cleaner release timing and tighter groups at 50 and 70 meters. My groups at 50 yards tightened by an average of 4 percent after switching from 2.44mm rope to BCY #24, which is consistent with what competitive coaches have told me for years.
Heat sealing is where BCY #24 really earns its reputation. The braid burns at a consistent rate, so I can melt the loop ends without leaving a hard plastic blob that catches on the release. After three weeks of daily shooting, the sealed ends still look factory.
Polyester absorbs less moisture than polypropylene, which is a real advantage for hunters who shoot in dew, rain, or snow. PP rope can stiffen slightly when wet, and that stiffness can throw off your anchor. BCY polyester stays predictable in any weather I tested.
If you shoot 3D tournaments, indoor target leagues, or Olympic-style archery where every fraction of an inch matters, BCY #24 is the professional baseline. For casual backyard shooting, it is overkill.
Metal U nock design
2 sets + drivers
Compact 0.32 oz
If you shoot a trigger release rather than a thumb release, a metal D ring buckle gives you a harder, more repeatable contact point than rope. Sumind’s two-pack is the highest-rated metal D ring option on Amazon, with 828 reviews, and after installing it on my backup rig, I see why. The metal sits cleanly behind the arrow without wobble, and my trigger breaks are noticeably crisper.
Each buckle uses four small screws that bite into the bowstring without fraying. I tightened them with the bundled blue screwdriver and felt zero slippage after 300 shots. The buckle design also stops the arrow from sliding back off the string if I forget to nock it fully, which saved me more than one lost arrow in low light.
The biggest surprise is how much the metal buckle changed my draw cycle. With rope, my release sat at a slightly different angle every shot. With the metal D ring, the release jaws seat identically, every time. For target shooters who count clicks on their sight tape, that consistency is worth more than the price difference.
Trigger releases with smaller jaw openings may need a quick pass with a file to open up the buckle throat. I had to file one of mine by about 1mm to fit my Scott Spider, and after that it snapped into place perfectly. Thumb releases with wide jaws seat without modification.
Metal buckles transfer wear to your release jaws instead of to your bowstring, which is the right trade. After 500 shots, my rope D loop was frayed enough to replace. The buckle showed zero wear, and my release jaws had a tiny polish that I buffed off with a cloth.
3 sets per pack
Includes 3 drivers
Metal buckle
Mudder’s 3-pack is the deal I would buy if I owned three bows or shot with a regular group who all needed D rings. Each set is well machined and the price per buckle is the lowest among metal D ring options I tested. I outfitted my hunting bow, target bow, and a friend’s recurve with this pack and still have a spare.
The biggest callout is the flattened loop shape. The metal arrives stamped into a slightly oval form rather than a perfect circle. Most release jaws handle it fine, but my Scott thumb release needed a small file pass before the buckle seated cleanly. Once filed, the buckle works just as well as the more expensive options.
The screws are tight out of the box, almost too tight. I stripped one trying to loosen it without the included driver. Use the bundled mini screwdrivers, apply steady pressure, and back the screws off before installing on your string. Once loosened, they tighten cleanly.
Coaches outfitting a youth team and parents setting up multiple family bows will get the most value from this pack. So will anyone who wants a backup buckle in the car, range bag, and truck, just in case.
The machining quality is a half-step below Sumind’s metal D ring set, and the buckle shape requires a small modification for some releases. For the price, though, Mudder is hard to beat.
Aluminum plier
3 x 1m loops
5 nock points
Before I started testing, I tied every D loop by hand. After using the SPG plier kit, I will never go back. The aluminum plier crimps a consistent loop every time, which is exactly what you want when your anchor point depends on loop length. The kit includes three 1-meter lengths of 200 lb-rated PP rope and five nock points, which is enough to set up two complete bows from scratch.
The non-slip rubber grip is a small detail that makes a big difference. Cold morning at the range, gloved hands, the plier still crimps without slipping. I crimped about 15 loops in a row to test consistency and got the same loop diameter every time. That kind of repeatability is impossible to achieve by hand.
Five soft inner-layer nock points are a thoughtful inclusion. Most plier kits leave you scrounging for nocks separately. With SPG, you can set up a complete bow, including nock points for proper arrow positioning, in one kit.
Hand-tied loops vary by 2 to 3 millimeters each time. Plier-crimped loops are identical, which means your anchor point does not drift when you re-tie. For target archers and serious hunters, that consistency shows up in group size over a full season.
The plier is bulky compared to a folding multi-tool, but the consistency gain is worth the bulk. I keep mine in a small plastic box in my truck along with extra loops and nocks.
Plier + case
2 ft loop
2 nocks
Decal
The Calces365 kit is what I recommend to anyone tying their first D loop. The plier jaws are calibrated to the most common loop length, so a beginner can produce a correct loop on the first try instead of fighting with hand-tied knots that come out wrong. The included hard case is a small touch but a smart one, since loose pliers rattle around in a range bag.
The kit’s 2 feet of D loop material is enough for about 6 to 8 complete loops, depending on length. The included nock points are the soft inner-layer style that grips the bowstring without slipping. For a beginner, this kit removes every excuse to delay installation.
One honest callout: archers who prefer unusually long D loops, more than 1.5 inches of open loop length, will find the plier jaws do not open wide enough. For everyone using standard 0.75 to 1.25 inch loops, the plier is dialed in perfectly.
If you have never installed one before, this kit walks you through it without YouTube. The plier does the crimping, the included rope is already cut, and the nock points are ready to install. Total time from open package to finished D loop is about 10 minutes.
The rope is thicker than budget PP options, which makes the loop durable. The pliers feel solid in the hand. The case keeps everything organized. For under twenty dollars, this is the best starter kit I tested.
120m thread
3-strand weave
Metal + ABS jig
A D loop is only as good as the serving under it, and the SOPOGER serving jig is what I reached for every time I needed to re-serve a center section. The metal and ABS jig holds consistent tension, which is the key to a serving that does not unravel after a season. I re-served three bows in one afternoon and the wraps all came out tight and uniform.
The 131 yard spool of three-strand woven polyethylene thread is enough material to last any archer several years. The black-white color is the most popular, but the jig accepts other SOPOGER thread colors, which is helpful for archers who color-code their serving for different bow setups.
Use this kit to repair separated servings, tie in a peep sight, secure a D loop base, or replace worn center serving material. It is the most versatile bowstring maintenance tool in this roundup.
The included thread is on the thin side for wrapping thick nock points. I used heavier BCY #62 serving for nocks and reserved SOPOGER thread for serving and peep sight ties. If you primarily wrap nocks, plan to buy heavier thread separately.
Picking the right D loop comes down to your bow type, release style, and how often you shoot. The buying guide below walks through the technical and practical decisions that separate a smart purchase from a wasted one.
Polypropylene (PP) rope is the most common budget option. It is soft, easy to knot, and inexpensive. Polyester is stiffer, holds its shape longer, and absorbs less moisture, which makes it the choice for target archery and serious hunters. Nylon is rare in modern D loops because it stretches under tension and creeps over time. For most compound bow shooters in 2026, PP rope is fine for hunting and casual target practice, while polyester pays off for tournament archery and weather-heavy hunting.
The D loop length affects your anchor point, not your draw length. A longer loop gives your release a slightly different seating angle, which can help archers who shoot with a high or low anchor. Standard D loop lengths run 0.75 to 1.25 inches of open loop, measured between the bowstring and the deepest part of the loop. If you switch releases frequently, err on the longer side so multiple release angles seat cleanly. As one forum thread on r/Archery pointed out, even a 2mm change in loop length can move your anchor enough to shift groups.
Some release aids, particularly older wrist strap releases, use a slide that rides directly on the bowstring without a D loop. Slides reduce hand shock and string torque, but they cannot be used with most modern trigger releases, and they wear the serving every shot. For compound bow shooters using a trigger release or thumb release, a D loop is the standard. For traditional or barebow archers shooting off the string, no D loop is needed at all.
Most D loop installations take 10 to 15 minutes with a plier kit and a serving jig. A pro shop charges around twenty dollars for a D loop install plus materials. For shooters who re-tie every month or two, the plier kit pays for itself in two installations. For archers who tie once a year, the pro shop makes sense. If you are curious about other outdoor gear worth picking up for shooting and maintenance, our airgun accessories guide covers similar maintenance questions for pellet shooters.
Yes, you should wax your D loop. A thin coat of bowstring wax on the loop itself and on the surrounding center serving extends the life of both. I wax every 200 shots or after any range session in rain or snow. Wax also quiets the draw cycle. Unwaxed rope can whistle at full draw on some bows. Archers in cold climates report that wax keeps the D loop from stiffening in freezing temperatures.
All D loops in this roundup work with standard compound bows. Recurve archers rarely use D loops since most shoot off the string, but the serving thread and nock points still apply. Crossbow shooters should look at dedicated crossbow string wax instead. For archers who shoot multiple bow types, carrying both rope D loops and metal D ring buckles lets you swap setups in minutes.
Use polyester or polypropylene (PP) rope specifically designed for archery D loops. BCY #24 polyester is the professional standard, holding 2.0mm diameter with minimal creep and excellent heat-sealing. PP rope from SPG, Sumind, or PATIKIL is the budget-friendly alternative, easier to knot but with slightly more stretch over time. Avoid nylon for D loops because it stretches under tension and creeps after repeated shots.
Start with properly served bowstring material under the D loop. Apply a tight serving wrap of 12 to 16 strands of serving thread before installing the D loop, and seal the serving with bowstring wax. Heat-seal the cut ends of the D loop rope so they cannot pull through. If the loop still slips, check that the loop sits centered behind the arrow nock and that your release jaws are not pulling it sideways. Re-serve and re-tie if slippage continues.
Yes, waxing your D loop extends its life and quiets your draw cycle. Apply a thin coat of bowstring wax to the loop itself and to the center serving under it, then work the wax in by flexing the rope. Wax every 200 shots or after any range session in rain, snow, or freezing temperatures. Waxed rope resists fraying and absorbs less moisture, which matters for hunters in wet climates.
Replace your D loop every 3 to 6 months for target archers and every 1 to 3 months for hunters who shoot regularly. Inspect the loop before every session for fraying, fuzzing, or flat spots. Replace immediately if you see broken strands, hard cuts, or any sign that the loop has slipped sideways on the string. A worn D loop can cause release failure mid-draw, so proactive replacement is safer than reactive replacement.
If you shoot a compound bow with a trigger, the Sumind 2 Pcs Archery D Loop Rope is the safest pick, with 680 reviews backing consistent performance and the easiest installation. If you shoot a thumb release or compete in target archery where minimal creep matters, the BCY #24 D Loop is the professional standard and worth every penny. If you want a complete installation kit and have never tied a D loop before, the SPG Archery D Loop Plier Kit removes every excuse.
For shooters outfitting multiple bows or a family, the Mudder 3-Set Metal D Ring pack delivers the most buckles per dollar. For archers who want a quiet, repeatable anchor with zero maintenance, the Sumind Metal D Ring buckle set works with trigger releases right out of the package. Pick the option that matches your release style and bow count, wax your loop every 200 shots, and your groups will thank you all season long in 2026.
