What does a bow sight do?

Recurve sights and compound scopes

A typical target recurve sight has an extension arm, a vertical track and a sight pin or aperture. Elevation moves the aiming reference up or down. Windage moves it left or right. Fine adjustment screws let you make small, repeatable changes.

Compound target sights commonly carry a scope housing with a dot or pin, sometimes a magnifying lens and a bubble level. A peep sight in the string provides a rear reference. Keep the scope centered in the peep before judging the pin's position on the target.

World Archery recurve rules prohibit magnifying lenses and levels in the sight; its compound rules permit them. Other competition classes have their own restrictions. Check the event rules before fitting a scope or changing sight accessories.

Single pin or multiple pins?

A single-pin sight gives you one aiming reference. On a movable sight, you set its position for the required distance. This keeps the view relatively open, but you need the correct setting before the shot.

A multi-pin sight gives separate pins for several distances. You choose the relevant pin without moving the housing for every distance change. Extra pins can crowd the view, and using the wrong one produces an avoidable miss. Some designs combine multiple pins with a movable track.

For either type, a steady anchor point matters. A perfectly set pin cannot compensate for moving your drawing hand or eye between arrows.

How do you adjust a bow sight?

1. Shoot a group at a distance where you can keep every arrow safely on the target. Judge the group center rather than a single poor release.
2. Move the front sight toward the group: up for high arrows, down for low arrows, left for a left group and right for a right group.
3. Make a small adjustment, secure the sight as instructed and shoot another group. Record the change before moving again.

Moving the front sight up makes you lower the bow to put the pin back on the same aiming spot. That is why high arrows call for an upward sight adjustment. Follow the actual movement of the sight head; knob markings can describe different things.

Keep sight marks with the setup

A sight mark is the track reading or tape position that puts your group on the aiming point at a particular distance. Record the distance units, arrow setup and extension position alongside it. Recheck marks after equipment changes.

A purchased or calculated sight tape still needs verification on your bow. Start close, then work outward within your safe range. At the lowest sight positions, check arrow and vane clearance beneath the scope. Keep your aiming references consistent while testing, and record the verified mark before changing distance.
