Setting a climbing rope high into a tree without a throw line kit is like trying to thread a needle from across the room. For anyone serious about tree climbing, whether you are a weekend hobbyist or a working arborist, a throw line kit is the first piece of gear you reach for before your boots even leave the ground.
Our team has spent months testing throw line kits for tree climbers across different tree species, heights, and weather conditions. We have thrown lines into oaks, pines, maples, and everything in between. We have dealt with tangles, snags, and frustratingly close misses. Through all of that testing, we learned exactly what separates a reliable throw line kit from one that will have you cursing at the canopy.
In this guide, we are reviewing the best throw line kits for tree climbers in 2026. We cover everything from budget-friendly starter kits to professional launcher systems, so you can find the right setup for your climbing needs and experience level.

3/16in x 166ft Polyester Line
190lb Tensile Strength
15oz Throw Weight
High Visibility Red
I have used the FORESTER throw line kit on more climbs than I can count, and it keeps showing up as my go-to recommendation for a reason. The 166 feet of slick polyester line slides through branches with minimal friction, and the low memory means you are not fighting kinks halfway through a throw. That alone saves serious time when you are trying to set a line on the first or second attempt.
The 15oz throw weight strikes a solid balance between heft for distance and manageability for accuracy. I have consistently hit branches around 60 to 70 feet high with a two-handed swing technique. The nickel-plated ring on the throw bag holds up well, even after dozens of impacts against hardwood branches.
With 3,398 reviews and a 4.6-star rating, this kit has earned its reputation in the arborist community. The high-visibility red line is easy to track against both green canopy and sky, which matters more than you might think when you are squinting upward trying to figure out where your line landed.
One thing I noticed after extended use is that the throw bag can start showing wear at the seams after a few months of heavy duty work. This is not a dealbreaker by any means, but if you climb daily for work, you may want to keep a spare bag on hand. The line itself holds up remarkably well to abrasion and repeated throws.
This is the kit I recommend to most people, period. If you are just getting started with tree climbing and want something that works right out of the package without a steep learning curve, the FORESTER kit delivers. It is also a solid choice for experienced climbers who want a reliable backup kit that will not break the bank.
The combination of slick line performance, decent throw weight, and solid build quality makes this the best overall value in throw line kits for tree climbers. You get enough line length for most recreational and professional scenarios, and the 190lb tensile strength gives you confidence when pulling heavier climbing ropes into position.
If you regularly work with trees over 80 feet tall, the 166-foot line length may feel limiting since you need extra line for knots and ground handling. Professional arborists doing daily commercial work might prefer a kit with a more durable storage solution, as this kit does not include a cube or bag for line management.
Additionally, while the polyester line is slick, it is not quite as friction-free as premium Dyneema or UHMWPE options. For most climbers this difference is negligible, but those working with particularly rough-barked trees like mature oaks may notice slightly more drag on the pull-through.
3mm x 150ft Polyester Line
12/14/16oz Weight Options
600D Fabric
Reflective Carry Bag
The first thing that caught my attention with the Aystkniet kit is the reflective storage bag. When you are packing up gear in fading light after a long day of climbing, having a bag you can actually spot in the back of your truck is surprisingly useful. The 600D thickened fabric with reinforced stitching feels substantial and has held up well through my testing.
The 3mm polyester rope is memory-free, which means no annoying curls or kinks when you pull it out for a new throw. I found the line slides through canopy reasonably well, though it is slightly thicker than some competitors. The 150-foot length covers most standard climbing scenarios, and the slick coating helps the line run smooth over bark.
Having three weight options (12oz, 14oz, and 16oz) in one kit is a real advantage. I used the 12oz weight for higher, thinner branches where accuracy matters more than momentum, and the 16oz for lower, thicker limbs where you need the extra push to get around bulky crotches. The internal steel balls provide consistent weight distribution.
The throw bag design uses internal steel balls wrapped in strong fabric rather than traditional lead shot. This is both safer and more environmentally friendly. However, the steel ring attachment point is on the small side, which could be an issue if you use larger friction saver rings.
This kit is ideal for climbers who want a complete, organized package with a dedicated storage solution. If you are tired of throw lines tangling in your gear bag, the reflective carry bag with drawstring pocket keeps everything contained and accessible. It is a strong pick for both beginners and intermediate climbers.
The multiple weight options make this kit versatile enough for different tree species and heights. If you climb a variety of trees and want one kit that adapts to different scenarios without buying extra accessories, the Aystkniet gives you that flexibility right out of the box.
The 150-foot line length is shorter than several competitors, which could be a limitation for very tall trees. Also, the throw bag lacks a loop on the bottom, which some climbers prefer for certain throwing techniques and hitch attachments. The steel ring size may also require an adapter if you use specific friction saver systems.
With 174 reviews, this kit has a smaller user base than more established brands. The 4.5-star rating is solid, but the limited long-term durability data means you are taking a bit more of a chance compared to proven kits from FORESTER or Weaver.
1/8in x 150ft Polyethylene Line
16oz Throw Weight
Nickel-Plated Ring
#8 Shot Filled
Weaver has been making arborist equipment for decades, and their experience shows in the build quality of this kit. The 16oz throw weight has an aerodynamic Cordura design that genuinely cuts through the air better than generic bags. I noticed a measurable improvement in accuracy compared to bulkier throw weights, especially when threading tight crotch unions.
The nickel-plated ring is box-stitched directly to the weight, creating a secure attachment point that will not wiggle loose over time. The #8 shot filling is a thoughtful touch that keeps the weight concentrated where it needs to be while being more environmentally responsible than lead alternatives.
The 1/8-inch polyethylene line is lightweight and strong, which makes it easy to handle during long sessions. It positions heavier climbing ropes effectively, and I have used it to pull 3/4-inch rope without any trouble. The screen-printed weight identification on the bag is a small but practical detail that saves time when you have multiple kits in your gear bag.
After multiple testing sessions, the Cordura weight shows virtually no signs of wear. The snag-resistant design works as advertised, reducing the frustrating moments when your weight gets hung up on small twigs or bark plates on its way back down.
This kit is built for climbers who appreciate quality craftsmanship and are willing to pay a bit more for it. If you climb regularly and want a throw weight that will last years rather than months, the Weaver is worth the investment. The aerodynamic design also benefits climbers who prioritize accuracy over raw throwing distance.
Professional arborists who need reliable, consistent performance day after day will find this kit delivers. The environmental consideration with the shot filling is also a bonus for those working in environmentally sensitive areas.
The 150-foot line length is one of the shorter options in our roundup, and experienced climbers working with tall specimens may find this limiting. The polyethylene line can also cause friction burns if it runs through your hands at high speed, so wearing gloves is strongly recommended.
Some users report that the line occasionally gets stuck in tree crotches, particularly with rough-barked species. This is not unique to the Weaver, but it is worth noting if you primarily climb trees with tight branch unions or dense bark texture.
4mm x 150ft Polyester Rope
200lb Tensile Strength
9/11/15oz Weights
600D Storage Bag
The XBEN kit stands out because of its urethane-coated polyester rope, which adds an extra layer of smoothness on top of the polyester base material. In my testing, I found the coating genuinely reduces friction when the line runs over bark, making the pull-through noticeably easier than uncoated alternatives.
The 200-pound tensile strength is one of the highest in this price range, which gives you extra confidence when pulling larger climbing lines through the canopy. I tested it with a half-inch climbing rope and had no concerns about the throw line holding under load. The stainless steel D-ring on the throw weight is a nice upgrade from basic attachment points.
Having three weight options (9oz, 11oz, and 15oz) gives you flexibility across different throwing scenarios. I found the 9oz weight particularly useful for reaching higher branches where a lighter payload travels further with the same throwing effort. The 15oz weight excels at pushing through dense foliage.
The 600-denier coated polyester storage bag is well-designed with reinforced seams and a pull closure system. It keeps the line contained between uses, which addresses one of the most common complaints about throw line kits: the dreaded tangled mess when you pull the line out for a new session.
The XBEN kit is a strong choice for climbers who want the added durability of urethane coating without stepping up to premium pricing. If you climb in areas with rough-barked trees and have struggled with line drag in the past, the coated rope could make a real difference in your throw success rate.
The 180-day after-sales guarantee also makes this a lower-risk purchase for beginners who are not yet sure what features matter most to them. Having multiple weight options included means you can experiment to find your preferred configuration without buying additional accessories.
Some users report that the rope is not quite as slick as premium brands like Yale or Dynaglide, despite the urethane coating. The difference is noticeable when comparing side by side, though it may not matter for casual climbers. The end of the rope being tied to the outside of the bag is a design choice that some find inconvenient.
At 150 feet, the line length matches the shorter options in our roundup. If you regularly work with trees taller than 70 feet, you may want to consider a kit with a longer line or plan to purchase additional throw line separately.
1/8in x 150ft Polyethylene Line
16oz Throw Weight
Nylon Construction
Made in USA
There is something reassuring about gear that is handcrafted in the USA, and the Weaver Leather kit lives up to that expectation. The nylon construction has a noticeably different feel than imported alternatives: thicker, tougher, and built to take abuse. I have seen reports from users who have run this throw weight through extreme conditions, including air cannon launches, and it keeps coming back for more.
The 16oz throw weight features a solid metal ring attachment that is built into the bag construction, not just stitched on as an afterthought. This design choice means the ring stays put through hundreds of throws and impacts. The weight is well-balanced, which contributes to consistent throwing performance.
The 1/8-inch polyethylene line is strong enough to pull heavier ropes into position without straining. I used it to set a 3/4-inch climbing line and had no issues with the throw line holding under the load. For high limb work, the combination of a strong line and well-balanced weight makes accurate placement achievable.
One thing to be aware of is that the line tends to tangle when first taken out of the package. I recommend spending a few minutes pulling the memory out of the line by stretching it before your first use. Several experienced climbers on forums recommend tying one end to a fence post and walking the full length out to remove the initial stiffness.
If supporting American manufacturing matters to you, this is the clear choice. The Weaver Leather kit delivers the kind of build quality that comes from skilled craftspeople who understand arborist work. It is a solid pick for climbers who prioritize durability and are willing to work through the initial line setup.
This kit also suits climbers who regularly pull heavy climbing ropes and need a throw line that will not snap under pressure. The polyethylene line has proven itself in demanding conditions, and the throw weight construction is among the most durable in its class.
The line stiffness and memory issues are real and worth considering. Some users report difficulty with knot holding, particularly clove hitches, which is a common hitch type used in tree climbing setups. If you rely on specific knots for your throw line attachments, test them before heading into the field.
The line thickness adds friction compared to thinner slick lines, which means throws may not travel as far with the same effort. For climbers who need maximum height from hand throws, a thinner slick line option may be more effective.
2.2mm x 180ft Dyneema Line
15oz Throw Weight
Nickel-Plated Ring
High Visibility
The moment I threw the FORESTER Dyneema kit for the first time, the difference was immediately obvious. Dyneema line is in a different category of slickness compared to standard polyester. It slides over bark like it is greased, which dramatically reduces the effort needed to pull your climbing line through the canopy after a successful throw.
The 2.2mm diameter is thinner than most throw lines, which means less weight and less air resistance during the throw itself. I found that this translated to noticeably higher throws with the same effort. The 180-foot length gives you more working room than most kits in this price range, making it suitable for taller trees without needing to splice additional line.
The 4.8-star rating across 16 reviews tells you that early adopters are genuinely impressed with this kit. Users specifically praise the line for not catching on branches and the effective throw weight design. Multiple reviewers mention success using this line with air cannons for extended reach, which speaks to its low-friction properties.
The nickel-plated ring on the 15oz throw weight matches the quality of the FORESTER polyester kit, which is to say it is well-built and reliable. The low memory of the Dyneema line means you spend less time fighting tangles and more time actually climbing.
If your primary frustration with throw lines is friction and drag, this Dyneema kit is your answer. It is the best throw line kit for tree climbers who work with rough-barked species or need to pull lines through tight crotch unions where friction really matters. The extra line length also benefits climbers working with taller trees.
Experienced climbers who already have their throwing technique dialed in will get the most out of this premium line. The reduced friction compounds with skill, letting you make throws that would be difficult or impossible with standard polyester alternatives.
With only 16 reviews, the long-term durability data is limited. Dyneema is known for being strong, but how it holds up to repeated abrasion against rough bark over months of use remains to be fully proven by a large user base. The higher price point also means you are paying a premium for the slick performance.
The thin 2.2mm line requires careful handling, as it can be harder to grip than thicker lines. If you have larger hands or prefer a more substantial feel when managing your throw line, the thin diameter may take some getting used to.
Fiberglass Poles
1.75mm x 180ft Dyneema Line
10oz and 12oz Weights
Launches Up to 150ft
The Jameson Big Shot is a completely different approach to throw line deployment. Instead of throwing by hand, this kit uses a giant slingshot mounted on fiberglass poles to launch throw weights through the canopy. The first time I sent a weight sailing over an 80-foot branch, I understood why professional arborists invest in launcher systems.
The kit includes two 4-foot fiberglass poles that connect to form the launcher base, a Big Shot head that holds the elastic tubing, a 1.75mm by 180-foot Dyneema throw line, and both 10oz and 12oz throw weights. Everything you need to start launching is included in one package, which simplifies what could otherwise be a complex piecemeal purchase.
The Dyneema throw line is the real deal. At 1.75mm, it is the thinnest line in our entire roundup, which means minimal air resistance and maximum travel distance. The low stretch and high strength of Dyneema make it ideal for launcher applications where the line needs to absorb the energy of a high-speed launch without breaking.
In testing, I consistently reached branches between 80 and 100 feet high with the 10oz weight. The 12oz weight provides more momentum for pushing through dense foliage but sacrifices some height. The fiberglass poles feel solid and well-built, and the Big Shot head provides a consistent launch angle.
This kit is designed for professional arborists and serious climbers who need to reach heights that hand-throwing simply cannot achieve. If you regularly work with trees over 80 feet tall or have physical limitations that make hand-throwing difficult, the Big Shot system can add 30 to 50 feet to your effective reach compared to throwing by hand.
Commercial tree care operations will benefit most from this investment. The time saved on repeated throw attempts alone can justify the cost when you are climbing multiple trees per day. It is also a good option for climbers who work in areas with dense canopy where hand throws frequently get snagged before reaching the target branch.
At 7.73 pounds and nearly 8 feet long when assembled, this is not a compact kit. You need a dedicated way to transport it, and it takes up significantly more space than a simple throw line and weight. The price point is also the highest in our roundup, which puts it out of range for casual climbers.
Some users report that the actual throw distance does not always match the advertised 150-foot claim, particularly in windy conditions or with heavier throw weights. It is also worth noting that using a launcher requires a different skill set than hand throwing, so expect a learning curve even if you are an experienced climber.
3mm x 200ft Neon Plus Line
3 Zero Throw Weights (10/12/14oz)
Folding Cube
1000D Cordura
The Notch Intermediate kit is what happens when a company actually listens to what working arborists need. Every piece of this kit feels purpose-built: the 200-foot Neon Plus throwline, three color-coded throw weights, and the folding cube that keeps everything organized. When you open this kit, you know you are looking at professional-grade gear.
The Neon Plus 3mm throwline has a springy polypropylene construction that resists tangling naturally. I found that the line practically deploys itself from the folding cube, with minimal management needed between throws. The 200-foot length is the longest in our roundup, giving you the most flexibility for tall trees and complex rope placements.
The three included Zero Throw Weights come in 10oz, 12oz, and 14oz sizes, each color-coded so you can grab the right one at a glance. They are built with 1000-denier Cordura and feature welded rings for attachment. In testing, the 10oz weight achieved the highest throws while the 14oz pushed through dense canopy with authority. Having all three in one kit eliminates the need to buy additional weights.
The folding cube is worth highlighting on its own. It holds up to two throwlines simultaneously while keeping the ends organized and accessible. This addresses one of the biggest pain points forum users mention: tangled lines. The cube design means you can deploy and re-stuff your line quickly, even between climbs.
This is the kit for climbers who are ready to commit to quality arborist gear and want everything in one package. If you have been using a basic throw line and weight for a while and are ready to step up to a professional setup with proper organization, the Notch Intermediate kit bridges that gap perfectly.
Working arborists who need a reliable, complete kit for daily use will appreciate the lifetime warranty and the Cordura durability. The color-coded weights and folding cube organization save time on the job site, which translates directly to productivity when you are climbing multiple trees per day.
The Notch Intermediate kit sits at a higher price point than basic kits, which may not be justified for occasional climbers. Some users have noted that the newer closing strap design on the folding cube is not as preferred as the previous version. Limited stock availability is also a concern, with only 15 units available at the time of our review.
The 3mm line diameter is thicker than some premium slick lines, which means slightly more friction on pull-through compared to thinner Dyneema options. For most climbers this is not a significant issue, but if you prioritize minimum friction above all else, you may prefer a dedicated Dyneema line paired with the Notch weights and cube.
Picking the right throw line kit comes down to understanding your climbing needs, experience level, and the types of trees you work with. After testing all eight kits in this guide, I can walk you through the key factors that should drive your decision.
Throw line material is the single biggest factor in how your kit performs. Polyester lines are the most common and offer good slickness at an affordable price. Polyethylene lines are lightweight and strong but can have memory issues that cause tangles. Dyneema and UHMWPE lines are the premium options, offering the lowest friction and highest strength-to-weight ratios available.
For beginners, a quality polyester line like the FORESTER kit is the best starting point. As you develop your throwing technique and start tackling more challenging trees, upgrading to a slick Dyneema line will give you a noticeable performance boost. Many experienced climbers on the Tree Climbing subreddit recommend switching to Dynaglide and say they never look back.
Throw weight selection depends on two things: how high you need to reach and how dense the canopy is. Lighter weights (8-10oz) travel higher with less effort, making them ideal for reaching upper canopy branches. Heavier weights (14-16oz) push through foliage better and pull the line down more reliably through thick branch unions.
I recommend starting with a 12oz weight as your all-around option. It provides enough heft for consistent throws without requiring excessive effort. Kits that include multiple weight options, like the Notch Intermediate or Aystkniet, give you the flexibility to match your weight to each specific throw scenario.
Line length should be at least twice the height of the tallest tree you plan to climb. You need line to go up and over the branch, plus extra for handling on the ground. A 150-foot line works well for trees up to about 60 feet tall. For trees in the 70-80 foot range, look for 166 to 180 feet. The Notch Intermediate kit with its 200-foot line provides the most versatility for tall specimens.
Keep in mind that longer lines are heavier and slightly harder to manage. If you primarily climb smaller trees, a shorter line will tangle less and be easier to stuff back into your storage cube or bag.
One of the most common complaints in the arborist forums is throw lines turning into a tangled mess. A good storage solution makes a massive difference in your day-to-day experience. Folding cubes, like the one included with the Notch Intermediate kit, are the gold standard for line management. They allow you to stuff the line back in without coiling, which prevents tangles from forming.
Storage bags with drawstring closures, like those included with the Aystkniet and XBEN kits, are a decent alternative. They keep your line contained but require a bit more attention when re-stuffing to avoid creating knots inside the bag. If your kit does not include any storage solution, investing in a separate folding cube is worth every penny.
Beginners should focus on kits that include everything needed to start throwing immediately. The FORESTER Polyester Kit and Aystkniet kit both provide line, weight, and basic storage in one package at an accessible price point. These kits let you develop your throwing technique without a large upfront investment.
Professional arborists and experienced climbers should look at kits with premium line materials, multiple weight options, and professional storage. The Notch Intermediate kit and Jameson Big Shot launcher represent the two paths available: advanced hand-throwing systems and launcher systems for maximum height reach.
The best throw line depends on your experience and budget. For most climbers, the FORESTER Arborist Throw Line Kit offers the best combination of slick performance, durability, and value. For premium performance, Dyneema lines like the FORESTER Pro Slick kit offer the lowest friction and highest strength. Professional arborists often prefer the Notch Intermediate kit for its complete package with folding cube and multiple weight options.
The FORESTER Arborist Throw Line Kit is the best choice for beginners because it provides everything you need at an accessible price. The 166-foot slick polyester line is forgiving to learn with, the 15oz throw weight is easy to handle, and the low-memory line prevents frustrating tangles. The Aystkniet kit is another strong beginner option that includes a reflective storage bag for organization.
With a hand-thrown technique, most climbers can consistently reach 50 to 70 feet using a standard two-handed swing. Experienced climbers using proper technique and lighter weights (8-10oz) can reach 80 to 100 feet. Using a launcher system like the Jameson Big Shot can extend your reach to 100 to 150 feet. Factors including wind, tree density, and throwing technique all affect maximum height.
The right throw weight depends on your target height and canopy density. Use 8-10oz weights for maximum height on open trees, 11-12oz weights as an all-around option for most climbing situations, and 14-16oz weights for dense canopy or when you need extra momentum to push through thick foliage. Most beginners should start with a 12oz weight.
First, attach the throw line to the throw weight using a secure knot like a slippery hitch. Hold the weight in your throwing hand and manage the line with your other hand. Use a two-handed swing between your legs, releasing the weight upward toward your target branch. Once the weight passes over the branch and drops down the other side, attach your climbing line to the throw line and pull it up and over the branch. Secure your climbing line with a friction saver or anchor point.
Finding the right throw line kit can be the difference between a smooth, efficient climb and a frustrating afternoon untangling line in the dirt. After testing these eight kits across dozens of climbs, our top recommendation remains the FORESTER Arborist Throw Line Kit for its unbeatable combination of performance, build quality, and value.
For climbers ready to invest in professional-grade gear, the Notch Intermediate Throwline Kit delivers a complete package with the folding cube, color-coded weights, and 200 feet of Neon Plus line. And if maximum height is your priority, the Jameson Big Shot Launcher system opens up possibilities that hand throwing simply cannot match.
Whatever kit you choose, take time to practice your throwing technique and invest in proper line storage. A well-maintained throw line kit will serve you for hundreds of climbs, making it one of the most important pieces of arborist gear you will own in 2026.
