Regarding peep sights for archery, there are two main types: fixed and adjustable. Fixed peep sights are permanently attached to the bowstring and have a fixed size and shape. They are typically less expensive and more straightforward, making them a popular choice for beginners. On the other hand, adjustable peep sights allow the shooter to change its size and shape to fit their needs better. It can improve accuracy by allowing for a more customized sight picture. However, adjustable peep sights are typically more expensive and require more knowledge and skill to use effectively. Choosing between fixed and adjustable peep sights will ultimately depend on the shooter’s preferences and skill level.
