Bow Sight: Types, Pins & How They Work

A bow sight is a device attached to a bow that gives archers a clear, consistent reference point for aiming. Mounted near the handle, it uses one or more pins — or a reticle — to help align each shot with the target more precisely. Whether you shoot recurve or compound, choosing the right sight architecture is one of the most impactful equipment decisions you'll make.

Types of Bow Sights

Single-Pin Sights

A single-pin bow sight features one adjustable pin that the archer sets for a specific shooting distance before drawing. Because there is only one pin in view, the sight picture stays uncluttered, making it a strong choice for target archers and bowhunters who want an exact aiming reference at any range. Many single-pin models use a sight tape — a printed strip with distance markings — calibrated to match a given arrow's weight and flight speed.

Fixed Multi-Pin Sights

Fixed multi-pin sights carry several pins set at predetermined distances, often ranging from three to seven or more. Pins are typically color-coded to help the archer distinguish them quickly, and fiber-optic pins gather ambient light to create a glowing reference point — useful in low-light conditions. Common fiber-optic pin diameters are .010, .019, and .029 inches; a larger diameter is easier to see but covers more of the target. This style is popular among hunters who need fast reference for multiple ranges without pausing to adjust the sight.

Multi-Pin Adjustable Sights

Adjustable sights combine multiple pins with the ability to fine-tune windage and elevation independently. They tend to be more complex than fixed designs but offer a high level of precision. Some feature a magnifying lens housing rather than bare pins — an option used almost exclusively by target archers, where the magnification also reveals any unsteadiness in the hold. USA Archery's Fixed Pins division specifies sights used without the aid of magnification, so check your competition rules before selecting a sight.

Setup and Accuracy Considerations

Mounting a bow sight is only the first step. Proper leveling across all axes — including adjustment for shooting uphill or downhill — is essential for consistent accuracy. A correctly calibrated bow sight level ensures the bubble reads true whether you're on flat ground or an angled shot. Understanding how bow cant affects arrow impact is equally important, since even a small tilt can send shots wide when using a sight.
