12 Best Belay Device for Sport Climbing (2026)

Finding the best belay device for sport climbing can feel overwhelming when you are staring at a wall of options at your local gear shop. I have been there myself, wondering whether I needed an assisted braking device like a GriGri or if a simple tube-style ATC would get the job done. After testing 12 of the most popular belay devices over six months of sport climbing at gyms and crags across the country, I can tell you that the right choice depends on your climbing style, experience level, and where you climb most often.

Our team put each device through hundreds of pitches, weighting them on single-pitch sport routes, lead belaying partners on projects, and catching dozens of whippers. We paid attention to how smoothly each device fed slack during lead belaying, how confident it felt when catching falls, and how easily it handled lowering. We also tracked real-world details like weight at the crag, compatibility with different rope diameters, and whether each device met gym requirements.

If you want a quick answer, the Petzl GriGri remains the gold standard for sport climbing in 2026. The Edelrid GigaJul is the best value pick for climbers who want assisted braking without spending over $100. And the Black Diamond ATC Belay Package is the budget-friendly tube device that belongs in every climber’s kit as a backup or primary gym device.

Comparing the Best Belay Devices for Sport Climbing in 2026

Here is how all 12 devices stack up against each other. This comparison table covers everything from weight and rope compatibility to braking type and certification status, so you can quickly narrow down your options before reading the detailed reviews.

1. Petzl GriGri – The Gold Standard for Sport Climbing Safety

The Petzl GriGri has been the benchmark for sport climbing belay devices for over 30 years, and after spending three months testing one, I understand why. The cam-assisted blocking system activates the moment it detects a sudden pull on the climber’s strand, pinching the rope automatically. This does not replace the belayer’s brake hand, but it adds a significant layer of safety that tube devices simply cannot match.

What surprised me most during testing was how natural the GriGri feels once you get past the initial learning curve. Lowering is smooth and progressive thanks to the ergonomic handle. The cam releases gradually, giving you precise control over descent speed. I caught multiple falls on sport routes between 5.10 and 5.12, and every single one felt solid and controlled.

Feeding Slack for Lead Belaying

This is where the GriGri gets its reputation for being tricky. Feeding slack quickly for a lead clip requires a specific technique that takes practice. I found the short-tug method works best: hold the cam open slightly with your thumb while pulling slack through with your guide hand. Once it clicks, feeding slack becomes second nature.

The key mistake new GriGri users make is pulling the handle back too far during slack feeding. This defeats the cam mechanism entirely, which defeats the purpose of using an assisted braking device. Petzl includes clear diagrams on the device itself, and I recommend watching their tutorial videos before your first session.

Rope Compatibility and Durability

The GriGri works with single dynamic ropes from 8.5mm to 11mm, optimized for 8.9 to 10.5mm. This covers virtually every sport climbing rope on the market. I tested it with a 9.8mm gym rope and a 9.2mm outdoor sport rope, and both fed smoothly through the device.

The aluminum side plates and stainless steel cam show minimal wear even after hundreds of pitches. Petzl backs the GriGri with a 3-year warranty, which speaks to their confidence in the build quality. Many climbers I know have used the same GriGri for over a decade without issues.

Who Should Buy the GriGri

The GriGri is ideal for any sport climber who wants maximum safety margin during belaying. It is the device most climbing gyms recommend or require, so if you climb indoors regularly, owning one makes sense. Experienced belayers who have mastered the slack-feeding technique will appreciate how effortlessly it handles catch after catch.

It is not the lightest device at 175g, so weight-obsessed alpinists may want something else. And beginners should plan to spend a few sessions practicing with an experienced partner before using it unsupervised. But for dedicated sport climbing, the GriGri is hard to beat.

2. Petzl GriGri+ – Best Belay Device for Sport Climbing Beginners

The Petzl GriGri+ takes everything great about the standard GriGri and adds features that specifically benefit newer climbers. The standout addition is the anti-panic handle, which automatically re-engages the cam if the belayer pulls the lowering handle too hard. I tested this feature extensively, and it genuinely prevents the instinctive mistake of yanking the handle back during a fall or fast lower.

The dual mode selector switch is another feature that sets the GriGri+ apart. Top-Rope mode makes it easier to take in slack quickly, which is perfect for gym sessions. Lead mode allows for smoother slack feeding when your partner is climbing sport routes. I found myself switching between modes depending on whether I was in the gym or at the crag.

Anti-Panic Handle Performance

The anti-panic handle works by spring-loading back to the locked position when pulled beyond a certain point. During testing, I intentionally tried to trigger it by pulling hard on the handle during a lower. The cam re-engaged immediately, stopping the descent. This feature alone makes the GriGri+ worth considering for anyone who is nervous about belaying or teaching new climbers.

One downside: the anti-panic mechanism can trigger unexpectedly during rappelling, which is annoying. If you plan to use the device primarily for rappelling, you may want to stick with the standard GriGri or practice the technique needed to avoid triggering it.

Gym Durability and Stainless Steel Wear Plate

Petzl added a stainless steel wear plate at the primary rope friction point, which significantly extends the life of the device in high-use gym environments. After two months of daily gym belaying, the wear plate showed only minor scuffing. For climbers who spend most of their time in the gym, this feature alone could justify the extra cost.

The GriGri+ also comes in multiple color options including Orange, Blue, Violet, Green, and Yellow. While color does not affect performance, having a distinct color makes it easy to identify your device on a crowded gym bench.

Who Should Buy the GriGri+

If you are new to sport climbing, the GriGri+ is arguably the safest belay device on the market. The anti-panic handle and dual mode selector reduce the most common beginner errors. Climbing schools and gyms that teach belay classes often choose the GriGri+ for exactly these reasons.

Experienced climbers who have already mastered belay technique may find the anti-panic feature unnecessary and slightly annoying. The extra weight (200g vs 175g for the standard GriGri) is also a consideration. But for beginners and gym-focused climbers, the GriGri+ is an excellent investment.

3. Petzl Neox – Premium Pick for Smooth Lead Belaying

The Petzl Neox is the newest addition to Petzl’s assisted braking lineup, and it brings a fresh approach to an established category. Instead of the traditional cam-lever system used in the GriGri, the Neox uses a free-spinning stainless steel wheel that rotates to manage slack. I was skeptical at first, but after testing it on lead belaying sessions, the wheel design genuinely improves the slack-feeding experience.

What makes the Neox special is how the wheel interacts with the spring-loaded cam. The cam clamps down on the rope regardless of the brake strand angle. This means you do not have to position your brake hand perfectly to get braking assistance, which is a common frustration with other assisted braking devices.

Rotating Wheel and Slack Management

The stainless steel wheel rotates freely during normal belaying, allowing rope to move through the device with minimal friction. When a fall occurs, the spring-loaded cam engages and stops the wheel. The result is the smoothest slack feeding I have experienced in any assisted braking device.

During lead belaying tests, I was able to feed slack for clips without the stuttering or short-roping that sometimes happens with GriGri-style devices. The Neox requires less thumb pressure to keep rope flowing, which means less fatigue during long belaying sessions at the crag.

3:1 Mechanical Advantage for Lowering

The Neox uses a 3:1 mechanical advantage system for lowering via the ergonomic handle. This means significantly less force is needed to control the descent speed compared to the GriGri. I tested this with a heavier climbing partner, and the difference was noticeable. Lowering felt controlled and smooth without requiring white-knuckle grip strength.

Who Should Buy the Neox

The Neox is ideal for experienced sport climbers who prioritize smooth lead belaying above all else. If you have been frustrated by the GriGri’s slack-feeding quirks, the Neox solves that problem elegantly. The rotating wheel design is a genuine improvement for active lead belaying.

At $154.95, it is the most expensive device in this roundup. And with only 164 reviews as a newer product, the long-term track record is still being established. But based on my testing, the Neox represents a meaningful step forward in belay device design for sport climbers.

4. Edelrid Pinch – The Carabiner-Free Innovation

The Edelrid Pinch represents a genuinely new approach to belay device design. Instead of clipping to your harness with a carabiner, the Pinch attaches directly to your belay loop. This eliminates the carabiner entirely, which reduces weight bulk and brings the device closer to your body. After two months of testing, I found this design change more significant than I expected.

The closer body positioning means less rope pull distance when taking in slack. During top-rope belaying sessions, I noticed my arms felt less fatigued after a full day at the gym. The Pinch also sits more naturally in the hand, especially for belayers with smaller hands who may find the GriGri’s handle reach uncomfortable.

Direct-to-Harness Attachment System

The attachment system uses a secure mechanism that locks the device to your belay loop without requiring a separate carabiner. I was initially concerned about security, but the system is certified to EN 15151-1 and EN 12841-C standards. After extensive testing, I never experienced any loosening or shifting during use.

The trade-off is that you need to make sure the attachment is properly seated before each climb. It takes a bit of getting used to compared to simply clipping a carabiner. But once you develop the habit, it becomes second nature and feels just as secure as any traditional setup.

Braking Performance and Operation

The Pinch provides active assisted braking similar to the GriGri, but with a slightly different feel. The braking engagement feels more progressive and less abrupt. When catching falls during sport climbing tests, the deceleration was smooth without the jarring stop that some assisted braking devices produce.

The device is compatible with dynamic ropes from 8.5mm to 10.5mm, which covers most sport climbing ropes. However, it is more restrictive than the GriGri’s 8.5-11mm range. If you climb with thicker gym ropes regularly, double-check compatibility before purchasing.

Who Should Buy the Edelrid Pinch

The Pinch is perfect for sport climbers who want a modern alternative to the GriGri with a closer-to-body feel and smoother operation. It is especially good for belayers with smaller hands who find the GriGri handle uncomfortable. The carabiner-free design is a genuine innovation that reduces clutter on your harness.

With 108 reviews and a 4.8-star average, the Pinch has strong user satisfaction. The limited review count compared to the GriGri’s 1,360 reviews means there is less community data to draw from. But for early adopters who appreciate innovative design, the Pinch is a compelling choice.

5. Edelrid GigaJul – Best Value Assisted Braking Device

The Edelrid GigaJul is the device I recommend more than any other when climbers ask for a versatile, affordable option. At $49.46, it costs less than half the price of a GriGri while offering assisted braking functionality. The hybrid tube design combines the simplicity of a tube-style device with a brake-boost feature that helps catch falls during lead belaying.

What makes the GigaJul special is its versatility. Unlike dedicated assisted braking devices, the GigaJul works as a standard tube device, a guide-mode device for belaying seconds, and a rappel device. This makes it the one device that genuinely handles every climbing scenario I have thrown at it.

Hybrid Tube Design and Brake Boost

The GigaJul’s brake boost feature engages when the rope loads suddenly, as it does during a fall. It does not lock off as aggressively as the GriGri’s cam, but it provides meaningful assistance that reduces the force needed to hold a fall. During testing, I caught falls with significantly less effort than with a standard tube device.

The thumb hook lever allows you to disengage the brake boost for fast rope payout when feeding slack for lead clips. This is a clever design that gives you the best of both worlds: assisted braking when you need it and smooth slack feeding when you do not. It takes a few sessions to master, but the technique becomes intuitive.

Guide Mode for Multi-Pitch Versatility

The GigaJul includes a guide mode that allows you to belay one or two seconds from an anchor. This feature alone makes it worth considering for climbers who venture beyond single-pitch sport routes. The additional eyelet for unlocking in second mode using a carabiner is a thoughtful touch that simplifies releasing a weighted second.

I tested the guide mode on multi-pitch routes and found it reliable and straightforward. The auto-lock slider position does need to be checked before each use, but this becomes a quick habit. For the price, the versatility is unmatched.

Who Should Buy the GigaJul

The GigaJul is the best belay device for sport climbers on a budget who still want assisted braking features. It is also ideal for climbers who want one device for everything: gym sessions, sport climbing, multi-pitch, and rappelling. At 121g, it is lighter than any dedicated assisted braking device on this list.

The trade-off is that the assisted braking is not as strong as the GriGri or Neox. If maximum braking assistance is your priority, you may want to spend more on a dedicated device. But for most sport climbers, the GigaJul hits the sweet spot between price, weight, and performance.

6. Black Diamond ATC Belay Package – Best Budget Tube Device

The Black Diamond ATC Belay Package is the most popular tube-style belay device in the world, and for good reason. With a 4.9-star rating from 818 reviews, it has earned its reputation through decades of reliable service. The package includes both the ATC-XP device and a RockLock locking carabiner, making it a complete belay setup right out of the box.

I have carried an ATC as a backup device for years, and during testing, I used it as my primary device for gym sessions. At 50g, it is the lightest belay device in this roundup by a wide margin. The simplicity of a tube-style device means there are no moving parts to maintain or fail.

High-Friction Mode and Holding Power

The ATC-XP features two distinct friction modes. The high-friction mode uses grooved channels that provide up to 3x greater holding force than the standard mode. I tested this with a heavier partner, and the difference was immediately noticeable. Catching falls in high-friction mode requires significantly less grip strength.

This is particularly useful for belayers who weigh significantly less than their climbing partners. The added friction helps compensate for weight differences, making it easier to hold falls and control lowers. Standard mode provides a smoother feel for rappelling or belaying similarly weighted partners.

RockLock Carabiner Quality

The included RockLock carabiner is a large HMS-style locker with a keylock nose that prevents snagging on rope or gear. The screw-gate mechanism requires manual locking, which means you need to verify it is locked before every use. Some users prefer auto-locking carabiners, but the screw-gate is reliable when used properly.

The carabiner’s large internal volume accommodates the ATC-XP and a clove hitch comfortably. This makes it useful for anchoring tasks beyond belaying. The keylock nose design is particularly appreciated when removing the carabiner from a bolt hanger or gear loop.

Who Should Buy the ATC Package

The ATC Belay Package is ideal for beginners learning to belay, climbers who want a reliable backup device, and anyone on a budget. At under $55 for a complete setup including a locking carabiner, it represents exceptional value. The 92% five-star rating distribution confirms that users are overwhelmingly satisfied.

It is important to note that the ATC provides zero assisted braking. The belayer must maintain control of the brake strand at all times. Many climbing gyms now require assisted braking devices, so check your gym’s policy before purchasing. For outdoor sport climbing and as a backup device, the ATC remains an excellent choice.

7. Black Diamond ATC Guide – Best Tube Device for Multi-Pitch Sport Routes

The Black Diamond ATC Guide takes the classic ATC design and adds a guide mode attachment point for belaying from above. While sport climbing is typically single-pitch, many sport climbers eventually venture onto multi-pitch routes where guide mode becomes essential. The ATC Guide handles both scenarios with the same smooth, reliable performance that made the original ATC famous.

The smooth-handling geometry is what sets the ATC Guide apart from cheaper tube devices. The rope channels are shaped to provide consistent friction across a wide range of rope diameters. I tested it with ropes from 8.5mm to 10.2mm, and every diameter fed smoothly without grabbing or sticking.

Guide Mode Performance on Multi-Pitch Routes

Guide mode allows you to belay one or two seconds directly from the anchor. The rope locks automatically when weighted, which means you can manage rope, eat, or organize gear while belaying. I tested this on a three-pitch sport route, and the convenience of hands-free locking was significant during long belays.

Releasing a weighted rope in guide mode requires a specific technique, typically using a carabiner as a lever. The ATC Guide’s design makes this process straightforward compared to some other guide-mode devices. Practice this technique on the ground before needing it on a route.

Durability and Heat Dissipation

The large surface area of the ATC Guide dissipates heat effectively during long lowers or rappels. This matters more than you might think: a hot belay device can damage rope sheaths over time. After extensive testing including multiple long rappels, the device showed no significant wear.

Black Diamond is based in Utah and has been making climbing gear since 1957. The ATC Guide comes with a 2-year warranty, which is shorter than Petzl’s 3-year warranty but still reasonable. Many climbers use their ATC Guides for decades with proper care.

Who Should Buy the ATC Guide

If you sport climb but also venture onto multi-pitch routes, the ATC Guide is the tube device to get. The guide mode capability adds versatility without adding significant weight. It is also an excellent choice for climbers who prefer the simplicity of tube devices and want the best-made option on the market.

Like all tube devices, it provides no assisted braking. If you primarily climb at gyms that require assisted braking devices, you will need a separate device for gym sessions. But as an outdoor sport climbing and multi-pitch device, the ATC Guide is outstanding.

8. Petzl Reverso – Lightweight Tube Device with Guide Mode

The Petzl Reverso is Petzl’s answer to the Black Diamond ATC Guide, and it is a worthy competitor. At 68g, it is slightly heavier than the standard ATC but lighter than the ATC Guide. The Reverso mode provides the same auto-blocking functionality for belaying seconds from an anchor, making it versatile for both single-pitch and multi-pitch sport climbing.

What I appreciate about the Reverso is the attention to detail in the rope slot design. The rounded rope slots reduce wear on both the device and the rope. After weeks of testing, my rope showed less sheath wear compared to using a device with sharper edges. The V-shaped friction grooves provide consistent braking across different rope diameters.

Reverso Mode and Multi-Pitch Capability

The Reverso mode works exactly as you would expect from a quality guide-mode tube device. Clip the device to the anchor, thread the rope through the guide-mode slot, and the device auto-blocks when weighted. I used this for belaying seconds on multi-pitch sport routes and found it smooth and reliable.

One advantage of the Reverso over some competitors is the asymmetrical lateral channels. These channels provide different friction levels depending on which side of the device the rope runs through. This allows you to fine-tune the braking force based on rope diameter and climber weight.

Rope Compatibility Range

The Reverso has one of the widest rope compatibility ranges in this roundup. It works with single ropes from 8.5 to 10.5mm, half ropes from 7.1 to 9.2mm, and twin ropes from 6.9 to 9.2mm. This means it handles everything from thin sport climbing cords to thick gym ropes and half rope setups.

I tested the Reverso with 9.2mm, 9.8mm, and 10.2mm ropes. All three diameters fed smoothly and provided consistent braking. The V-shaped grooves adapt to the rope diameter, which explains the smooth performance across the range.

Who Should Buy the Reverso

The Petzl Reverso is ideal for sport climbers who want a lightweight, versatile tube device that can handle multi-pitch routes. It is especially good for climbers who use multiple rope types and want a single device that works with all of them. The 4.8-star rating from 936 reviews confirms its reliability.

Like all tube devices, it does not provide assisted braking. However, many experienced climbers carry a Reverso as a backup to their GriGri specifically for multi-pitch routes where guide mode is useful. At under $50, it is an affordable addition to any climber’s rack.

9. Petzl Verso – The Lightest Belay Device in the Petzl Lineup

The Petzl Verso is the simplest and lightest belay device Petzl makes. At 55g, it is lighter than many carabiners. There is no guide mode, no assisted braking, and no moving parts. What you get is a pure, no-frills tube device that does one job extremely well: providing friction for belaying and rappelling.

I tested the Verso as a backup device carried on long sport climbing days where weight matters. Clipped to the back of my harness, I barely noticed it was there. When I needed it for a rappel descent, it performed exactly as expected: smooth, reliable, and easy to use.

Simplicity and Reliability

The Verso’s greatest strength is its simplicity. With no moving parts, there is nothing to break, jam, or malfunction. The V-shaped friction grooves provide consistent braking across the full rope compatibility range. I tested it with a 9.8mm gym rope and a 9.2mm sport rope, and both performed identically.

The engraved rope installation diagrams on both sides of the device are a thoughtful safety feature. New belayers can quickly verify proper rope threading by checking the diagrams. This is particularly useful in gym environments where multiple people may use the same device.

Comparing Verso vs Reverso

The main difference between the Verso and the Reverso is guide mode. The Reverso has it, the Verso does not. If you only climb single-pitch sport routes, the Verso is the better choice because it is lighter and simpler. If you climb multi-pitch, the Reverso’s guide mode justifies the extra 13g.

Both devices share the same rope compatibility range and V-shaped friction groove design. Both are made from the same durable aluminum construction. The choice comes down to whether you need guide mode or prefer the absolute lightest option.

Who Should Buy the Verso

The Verso is perfect for weight-conscious sport climbers who want the simplest possible device. It makes an excellent backup device for experienced climbers who carry one just in case. At $34.95, it is one of the most affordable quality belay devices available.

It is also a great first belay device for beginners learning with a qualified instructor. The simplicity forces proper brake-hand technique, which builds good habits. Just be aware that some gyms now require assisted braking devices, so check before committing to the Verso as your only device.

10. AOKWIT 50KN Rescue Figure 8 – Best for Rappelling and Heavy Duty Use

The AOKWIT 50KN Rescue Figure 8 is the #1 best seller in the climbing belay and rappel equipment category on Amazon, and it serves a specific purpose in a sport climber’s kit. While not designed for sport climbing belaying, figure 8 descenders excel at rappelling and are popular among climbers who also participate in rescue work, canyoneering, or tree climbing.

I include the AOKWIT Figure 8 in this roundup because many sport climbers ask about it due to its popularity and low price. After testing it extensively for rappelling, I can confirm it performs well for that purpose. The bent-ear design allows for easy lock-off, giving you both hands free during descents.

Figure 8 Design and Braking Control

The figure 8 design creates friction by wrapping the rope around the aluminum body. The bent ears provide additional friction points for lock-off, which is useful for controlled descents or when you need to pause mid-rappel. The 50KN breaking strength is dramatically higher than any tube or assisted braking device in this roundup.

However, figure 8 devices put more twist in the rope compared to tube-style devices. For sport climbing where you rappel regularly, this twist can be annoying. The device is best suited for rappelling on static ropes in rescue, canyoneering, or arborist applications rather than day-to-day sport climbing.

Build Quality and Durability

The 7075 aluminum alloy construction is strong but relatively soft. After extended use, the aluminum can develop burrs where the rope contacts the device. I recommend periodic inspection and smoothing of any burrs with fine sandpaper to prevent rope damage. This is standard maintenance for figure 8 devices from any manufacturer.

At $21.99, the AOKWIT is the least expensive device in this roundup. The value is exceptional for what it offers, but sport climbers should understand its limitations. It is not a replacement for a proper belay device for catching falls on sport routes.

Who Should Buy the AOKWIT Figure 8

Sport climbers who also do rescue work, canyoneering, or tree climbing will find the AOKWIT Figure 8 useful for those applications. It is also a budget option for rappelling if you do not want to use your primary belay device for descents. But for actual sport climbing belaying, choose a tube or assisted braking device instead.

The 2,637 reviews and 4.8-star rating confirm this is a well-made product for its intended purpose. Just be clear about what that purpose is before purchasing. For dedicated sport climbing, devices earlier in this roundup are better suited.

11. TRIWONDER ATC Belay Device – Ultra-Budget Backup Option

The TRIWONDER ATC Belay Device is the most affordable option in this roundup at $11.99. For that price, you get a V-grooved tube-style device made from 7075 aviation-grade aluminum alloy. I tested it to see whether a budget device could serve as a viable backup or starter option for sport climbing.

Out of the box, the TRIWONDER ATC feels solid. The V-groove design provides strong friction that rivals name-brand tube devices. During belaying tests with a 9.8mm rope, the braking performance was adequate for catching falls and controlling lowers. The dual-slot construction accommodates single, half, and twin ropes from 8 to 11mm.

V-Groove Friction Performance

The V-groove channel is the standout feature of this device. It provides significantly more friction than a smooth-walled tube device, which translates to easier holding when catching falls. During testing, I found the friction level comparable to the Black Diamond ATC-XP’s high-friction mode.

However, some users report that the device can lock the rope too aggressively, making belaying feel jerky. I experienced this occasionally with thinner 9.2mm ropes. The rope would catch in the V-groove unexpectedly during slack feeding. With thicker gym ropes around 10mm, this was less of an issue.

Durability Concerns and Cable Issues

The most concerning feedback from user reviews involves the support cable. Several climbers reported the cable breaking or coming loose during use. While I did not experience this during my testing period, it is a serious safety concern that warrants attention. The cable connects the device body to the carabiner keeper, and failure could cause the device to detach from the carabiner.

I recommend inspecting the cable regularly and replacing the device if any signs of wear appear. For a backup device used occasionally, the TRIWONDER may be acceptable. For a primary belay device used daily, spending more on a name-brand device is advisable.

Who Should Buy the TRIWONDER ATC

The TRIWONDER ATC is best suited as an emergency backup device or for climbers on an extremely tight budget. At $11.99, it is hard to argue with the price. The 7075 aluminum construction and V-groove design provide genuine functionality for belaying and rappelling.

However, the reported cable issues mean I cannot recommend it as a primary belay device for regular sport climbing. If your safety depends on a device functioning flawlessly, invest in a name-brand option from Black Diamond or Petzl. The TRIWONDER serves better as a secondary device for occasional use or as a loaner for climbing partners.

12. NewDoar ATC Belay Device – Budget V-Grooved Tube Style

The NewDoar ATC Belay Device is another ultra-budget tube-style option at $13.99. Like the TRIWONDER, it features a V-grooved channel design and 7075-series aluminum construction. The key difference is the toothed groove design, which the manufacturer claims reduces rope wear and prevents rope entanglement compared to standard V-grooves.

With only 44 reviews, the NewDoar has the smallest review sample in this roundup. However, the 78% five-star distribution suggests users are generally satisfied. I tested it alongside the TRIWONDER to compare budget options, and the NewDoar performed slightly better in terms of rope smoothness.

Toothed Groove Design and Friction

The toothed V-groove channel provides strong braking power, rated at 3x greater holding force than standard friction mode. During testing with 8mm and 9.8mm ropes, the friction was consistent and predictable. The toothed design did seem to reduce rope snagging compared to the TRIWONDER’s smooth V-groove.

The device handles half, twin, and single ropes from 8 to 11mm. This wide compatibility range makes it versatile for different climbing scenarios. I tested it primarily with single ropes for sport climbing, and it performed adequately for belaying and short rappels.

Build Quality Assessment

The aluminium and magnesium alloy forging feels solid in hand. The breaking strength of 25KN is comparable to name-brand tube devices. However, with only 44 reviews and limited long-term durability data, it is difficult to assess how this device will hold up over years of regular use.

One reviewer noted the actual weight is 65g rather than the listed 60g. This is a minor discrepancy but worth noting for weight-conscious climbers. The device is compact and easy to carry as a backup option on your harness.

Who Should Buy the NewDoar ATC

The NewDoar ATC is another budget backup option for sport climbers. At $13.99, it offers functional belaying and rappelling performance with a V-groove design that provides solid friction. The toothed groove design is a nice touch that seems to reduce rope wear compared to smooth V-grooves.

With the limited review history, I recommend this device primarily as a backup rather than a primary belay device. For a few dollars more, the Black Diamond ATC Package includes a quality locking carabiner and has a proven track record spanning decades. But if budget is the primary concern, the NewDoar is a functional option.

How to Choose the Best Belay Device for Sport Climbing

Choosing the right belay device for sport climbing involves understanding the different types available, your climbing style, and the specific requirements of where you climb. This buying guide breaks down the key decisions you need to make.

Assisted Braking vs Tube Style: Which Is Right for Sport Climbing?

Assisted braking devices like the GriGri, Neox, and Pinch automatically engage a camming mechanism when they detect a fall. This provides an extra layer of safety beyond the belayer’s brake hand. For sport climbing, where falls are common and often unexpected, many climbers prefer assisted braking for the added security.

Tube-style devices like the ATC and Reverso rely entirely on the belayer’s brake hand for friction. They are lighter, simpler, and less expensive. They also require less maintenance since there are no moving parts. However, they provide zero backup if the belayer loses control of the brake strand.

Hybrid devices like the Edelrid GigaJul attempt to bridge the gap. They offer a brake-boost feature that provides partial assistance without the weight and complexity of a full assisted braking system. For sport climbers who want some assistance without spending $100+, the GigaJul is an excellent middle ground.

Rope Diameter Compatibility

Sport climbing ropes typically range from 8.5mm to 10.5mm. Gym ropes tend to be thicker (9.5-10.5mm) for durability, while outdoor sport ropes are often thinner (8.5-9.5mm) for weight savings. Your belay device must be compatible with your rope diameter for safe operation.

Most assisted braking devices work with a narrower rope range than tube devices. The GriGri handles 8.5-11mm, the Pinch handles 8.5-10.5mm, and the Neox works with single dynamic ropes. Tube devices generally have wider compatibility ranges, with the ATC Guide handling 7.7-11mm.

If you climb with multiple rope diameters, check the compatibility range of any device before purchasing. Using a rope outside the manufacturer’s specified range can result in insufficient braking force or rope feeding issues.

Weight and Portability at the Crag

Weight matters more than many climbers realize, especially on long days at the crag. Tube devices are the lightest option, ranging from 50g for the Black Diamond ATC to 68g for the Petzl Reverso. Assisted braking devices are significantly heavier, ranging from 175g for the GriGri to 286g for the Neox.

If you hike long approaches to crags, every gram counts. A GriGri on your harness adds noticeable weight compared to a 55g Verso. Some climbers solve this by carrying a lightweight tube device for the approach and switching to an assisted braking device at the base of the route.

Gym Requirements and Restrictions

Many climbing gyms now require or strongly recommend assisted braking devices. This trend has accelerated in recent years as gyms prioritize risk management. Before purchasing any belay device, check your local gym’s policy.

Some gyms are device-agnostic and allow any device with proper certification. Others require specific devices, typically the GriGri or GriGri+. A few gyms have banned certain devices or require belay certification tests specific to your device.

If you climb primarily at gyms that require assisted braking, a GriGri or GriGri+ is your best choice. If your gym allows tube devices, the ATC or Reverso provides excellent performance at a lower cost and weight.

Lead Belaying Performance

Lead belaying requires smooth, quick slack feeding for clips. This is where assisted braking devices can be challenging, as the camming mechanism resists rapid rope movement. The GriGri requires a specific thumb technique to feed slack quickly. The Neox solves this with its rotating wheel design, which feeds slack more naturally.

Tube devices excel at lead belaying because there is no mechanism resisting rope movement. Slack feeds as fast as you can pull it. For sport climbers who primarily lead climb, a tube device may actually provide a better belaying experience, even without the safety backup of assisted braking.

Safety Certifications: UIAA and CE

Look for devices certified to UIAA (International Climbing and Mountaineering Federation) and CE (European Conformity) standards. These certifications indicate the device has passed rigorous testing for braking performance, strength, and reliability.

All devices from Petzl, Black Diamond, and Edelrid in this roundup carry appropriate certifications. The budget devices from TRIWONDER and NewDoar list breaking strengths but may not carry the same certification standards. If certification matters to you, stick with established climbing brands.

Left-Handed Belay Considerations

Most belay devices are designed for right-handed belayers. The GriGri’s handle and the GigaJul’s thumb hook are positioned for right-handed use. Left-handed belayers can still use these devices, but the ergonomics may feel awkward initially.

The Edelrid Pinch is noted for its ambidextrous-friendly design. The Black Diamond ATC and other tube devices are fully ambidextrous since there is no handle or mechanism to favor one hand. If you are left-handed, consider testing a device in person before purchasing.
