Using a spear or dart is one of the oldest ways of hunting. The people from ancient times upgraded the way to use a spear/dart and made the atlatl. It is a tool that is uses leverage to increase the velocity of each throw.
The spear can be thrown well over a 100 meters but it is more accurate at distances of 20 meters or less.
This is an ancient but proven way to hunt for food in a survival situation. Once you have your spear, there are only a few things you need to make an atlatl. The video doesn’t really give you specifics on how to make the atlatl but shows you exactly how to use it.
I really think that this is a very great way for you to at least learn the basics on how to use the atlatl.
Just watch the video, enjoy and learn.
