Installing your climbing line and friction saver in a tree starts with a good throw line. We've gathered a selection of the best throw lines for tree climbing in one place. You'll find high-strength Dyneema and Spectra throw lines for professional use as well as inexpensive 1/8” throw line.
WesSpur throw line kits come complete with throw line, throw weights, and throw line storage all in one.
Made from Dyneema fiber, Samson's Zing-It yields the highest strength, lightest weight, lowest stretch and longest wear life available. Samthane coating adds wear life and ensures the knot-holding capability. Available in 1.75mm (400 lb. average strength) and 2.20mm (580 lb. average strength).
Jet Set is a redesign of the best-selling Jet Set throw line. This 100% pre-stretched spectra throw line flies great with hand-throws or the Big Shot. High-strength and low-memory after the break-in period. Best used with a 12oz or heavier throw line. 1.75mm has 450 lb. average strength, 2.20mm has 650 lb. average strength.
1.8mm diameter, 1,000 lb. tensile strength. Colors may vary.
Teufelberger Ropes' DynaGlide is a highly-visible, snag-free throw line made 100% Dyneema treated with a vinyl coating. Glides easily over branches allowing lighter throw weights. 1.8 mm. 1,000 lb tensile strength. Colors may vary.
2.2mm shaoLINE throw line by Teufelberger consists of a cover made of Dyneema® and polyethylene monofilaments and a polyethylene core. The PE monofilaments make this throwline more abrasion resistant and the cover tough. Resists kinks and tangling.
Petzl's Airline throw cord is an excellent choice for performance throw line. Airline has a Dyneema sheathe for added toughness and abrasion resistance over an EVA core. This construction helps it stay nice and round and glide through the tree easily. Airline is very light, so you don't need a very heavy throw weight. Airline throw cord is just the right blend between flexible and stiff for a cord that throws easily right out of the bag or cube and resist knotting and tangling.
Airline is 1.8mm in diameter and has a tensile strength of 550 lb (250 kg).

“I purchased this throwline this spring. At first I was very frustrated with it but I assumed its performance would improve as it broke in. It didn't. Instead it may have gotten worse. Even after carefully flaking it into the throwline cube it knotted up constantly. Birds nest after birds nest. I harassed a petzl rep about it and he just shook his head in agreement. Switched to Samson zing it, 1,000% improvement. It's almost difficult to tangle even when maybe you deserved a tangle. ”
2mm polyester-cover throw line from Marlow ropes sold in 50m (164 feet) spools. This throw line is a great value, and is high-strength and long-wearing for reliable throwing time and time again.

“Marlow ropes is a new player in the US, and we are offering some of their products this year. One "new" line form them is a simple offering. They have a 2mm Polyester throwline. (think super small prusik cord). It is slick, has no memory, throws well out of a cube, and is very easy on the wallet. The old "slick line" and Target line can be relegated to the garage sale this summer. I was amazed at how functional this line was for hand throwing. It is slippery enough to bring the bag back down, does not tangle bad, and for those on a budget where the more expensive offerings are out of reach, you now have a very viable option for professional use. We are placing this in our kits this year making an excellent upgrade for the entry level kits. Better gear equals more money and easier days.”

“First impressions after the first day out with this line:
I am comparing it to Target Line, the hard diamond-braid polyethylene line that I have learned to make work in a BigShot. I am working Southern Yellow Pine.
Visibility: Marlow is excellent, especially under low-light conditions. Pre-rigging a tree at dusk last week for work the next morning, the line was extraordinarily easy to see against a darkening overcast sky. Next day, in the sun, it was even better.
Slickness: Compared to Target Line, it is not quite as slick, requiring a bit more weight to pull through multiple branches. A side effect of the slightly rougher surface is that it seemed more prone to saw its way into crotches when hauling up the heavier rigging line. I did have a problem on a couple of tight-vee crotches but was able to clear the throw line without having to go up after it. I would actually prefer a slicker finish.
Flexibility: It is definitely more supple than Target. When it tangles on a shot, it knots down fairly tightly. I shoot out of a five-gallon bucket instead of a line cube, and have learned to carefully manage the twist in Target between shots. The Marlow seemed to be settling down by the time I finished this piece of work, so I'll be willing to wait and see how it does when fully broken in. Probably need to manage twist just as carefully. My first impression is that it was tangling/knotting worse than the Target, but I started doing better with it.
Size: smaller than Target. No impact on functionality.
Other: ability to grip and hold the rigging line is better, probably due to being more flexible and having a slightly rougher coat. It held perfectly with fewer half-hitches above the girth hitch.”

“This throw line stinks! It has way to much stretch, does not run good through crotches, breaks easily and gets tangled. Have to stay with zing-it. ”

“If Dr. Evil created a throw line it would be Marlow throwline. Sure it's cheap, Has a nice supple feel slipping through the fingies,and a great high vis colour. But that's where the fun ends, Tangles going into the cube out of the cube, it even managed to wrap the pull handle on my big shot pouch mid shot, W.T.F.!!!
Please, do yourself and others a favor, spend the extra on some Zing it or Dyna glide, you'll thank me later! ”
Target Line is a new economy throw line from the makers of the excellent Jet Set throw line. Target Line is 1/8” diamond braid polyethylene line, and is manufactured to be extremely slick to slide easily through the canopy. Target Line is more tightly braided than other economy throw lines such as Slick Line, to reduce snagging. Target Line has a neon orange and yellow striped pattern which really makes it easy to spot in the trees.
A hard, waxy finish give this affordable 1/8" diamond braid throw line its name. Slick Line features improved pliability from previous years. Great for pulling tool up to the climber, tying down loads, as an inexpensive throw line, and lots more uses around the work site.
