Atlatls are super fun, but very difficult to master. Often times people say, "Ahhh, It looks simple enough, I'll just build my own." Truth is it's a little more complex than people realize. Anyone can throw a stick with a stick, but building a well balanced set can make the difference in achieving accuracy faster or banging your head against the wall. I always encourage folks to build their own sets, but if you want to get started with a good proven set, look no further.
Atlatls pre-date the bow and arrow and were used to hunt everything from frogs to wooly mammoths. Most people think the atlatls were a weapon of luck and little accuracy. As you will see in the video below, great accuracy can be achieved with enough practice.
