The desired material is called

• I used an arborist throw-line kit. Basically a 12 oz beanbag (filled with metal shot), with a loop attached that you tie onto some thin/strong dedicated throw line (2mm) and then you launch that into the canopy using your preferred method. I use a one-handed underhand pendulum style throw (good for about 50ft). Arborists also use sling shots (100ft range) and air cannons (200ft range). You can also do pendulum style throwing two handed (70 ft range), or just pitch it like a baseball or a grenade (35' range). You get it up over a strong limb or crotch, and then then once it's in place you tie your climbing rope onto the throwline and pull it up and over, and then set an anchor at the base of the tree.
