Throw bags are a good means of positioning throw lines over tree branches either by hand or by a slingshot. Typically, they are made of vinyl or leather and are fitted with a ring to where the throw line is tied. There is a little problem with throw bags, though. It can get torn when snagged by a sharp tree bark or twig. And the ring can also get stuck in between tight crotches.
The Treepedo Rope Access Tool eliminates these problems. This is a cylindrical tool made of hard anodized aluminum whose both ends terminate in a cone that has been cut open at the tip. The cylinder is divided into two parts, the nose and base cones, with the latter having a larger diameter than the former. This allows the insertion of the nose cone into the base cone. A nut locks the two cones together. The Treepedo also comes with a stainless steel weight that fits inside the cylinder and a split ring for attachments.
The throw line is inserted into the hole at the tip of the nose cone and either knotted or spliced and locked with a cotter pin to hold it in place. The stainless steel weight is then put into the base cone, after which the two cones are attached making them ready for throwing.
The Treepedo is launched just like throw bags, either by hand or a slingshot. The difference between them is that the former slices through the air and leaves, and glides over twigs and branches while a throw bag may smash into them. This is possible because of its aerodynamic design and a reduced friction point.
In the event that the Treepedo does not fall back to the ground and gets stuck up in the branches, retrieval is easier because of its conical point, cylindrical body, and the absence of a ring. If the throw is successful, you can use it as a handle to pull the throw line down after tying the climb line to its opposite end.
