Invention for retrieving throwbag from distance 2 Months, 2 Weeks ago  
I want to share a solution I invented for retrieving a throwbag from a great distance (say when going from one tree to the next). It is a rather simple device made of wood with a bit of wire that can easily be carried aloft with other common gear. You can learn all about this invention from a movie I posted to YouTube.

Enjoy!

I like it! It does the same as a grapnel but in a more controlled way - less chance of getting tangled up. I myself invented a new type of grapnel with arms twisted to the sides in a spiral to make it more effective at catching a dangling line. New Tribe are producing the first ones right now!

I think more people should find new ways to solve problems rather than just shopping for what's already available. We all have to potential to be inventors

Hi
Thanks a lot for your ideas and videos. I really enjoyed them.
By the way, I have a simple image(not yet tested)of retrieving a throwbag.
If you reave me any comment or message on my illustrated method, many thanks will follow.

That looks like a clever solution!

What language is the webpage written in?

That's a viable technique Pabllo. If you substitute a Grapnel for the second throw bag or hang a grapnel off the throwbag it will be much easier to snag the line.

My method is to throw the bag over the destination branch, let it go down enough so that there is enough line to make it back to where I am. Girth hitch a Grapnel (what New Tribe sells or one you make) to the same throwline. The throw bag needs to be slightly heavier than the Grapnel depending on bark texture. I use an 8 oz (for smooth bark) or 10 oz bag. Back to the Grapnel, it's girthed to the throwline midline. Let out additional throwline, the Grapnel moves towards the target branch. If the bag won't pull down enough to move the Grapnel just bounce the Grapnel gently upward, that will take weight off the line, the bag will drop and the Grapnel will move forward. Allow the Grapnel to hang down below the target branch, swing it gently to snag the target line which is over the other side of the branch. When you snag the line pull the Grapnel back. Now you'll see why you need to let the bag drop far enough below the branch, if there is not enough line out the bag won't make it all the way back to you. That's it.

I've used this technique when there obstructing branches in the path of the traverse, the Grapnel can be moved over obstructions as you send it towards the target. I've used it to blind grab the line on the other side of a tree trunk. Works great. I no longer keep my Grapnel on its own tether line, it's always added to the throwline as described above. You're only limited by how far you can throw horizontally and how much throwline you carry on your harness. I use 2mm ZingIt, if you use heavier throwline you'll need to use more throw weight and perhaps add weight to the Grapnel.

Hi Tom.
Thanks for your interest on my post.
