The bow is a great tool. You can hunt or just have target practice. But soon after you will have many questions. What type of bow? Quick release or not? What kind of arrows? What style? This guide should help you get started.
There are two types of bows compound and recurve. Compound is more complicated and harder to repair but is more power for less draw. The recurve is simpler and easy to use but it requires more strength to draw. Personally I would recommend the compound for it's ease of use.
