Without any explanation of what a string sight is, and not seeing the arrow hit, and vehicle traffic in the background of the line of fire, I'd say his video doesn't show much of any use. What is a string sight? How does it work? Why did he shoot with that kind of a hold and release?
Ron, I know that you know a lot about archery, so this obviously means something to you. What more information can you provide to fill in the large blanks?
