This concept was the original Bow Sling ( Andy Vale once held a world record for most arrows in the air at once ). He discovered that the arrow catch sometimes hit the feathers on launch.
That was a great informative video. Good self defense, but never forget to bring back up if the enemy comes so close. Brother what if I use more strong rubber tube?
I like the D loop for grabbing the dart. That's a really good method for achieving maximum draw.
Also I like the method of nocking the dart head to the tubes. It looked like a short straight piece of rod or wire. If you see this post could you please confirm?
Too bad you have to put up with some of the dumbest comments I've ever seen such as someone calling it a kid's toy or just a balloon shooter. Gosh, clearly they failed primary school & I am sure they are why many don't bother creating videos.
