Frequently Asked Questions
How do sight tapes work?
Sight tapes are calibrated strips attached to your bow sight that allow you to set precise aim points for various distances. They're created by shooting known distances and mapping sight positions.
How do I set up multi-pin sights?
Start by setting your top pin at your closest distance (usually 20 yards). Then set each subsequent pin at 10-yard increments (30, 40, 50 yards). Fine-tune by shooting groups at each distance.
What affects arrow drop?
Arrow speed (draw weight and arrow weight), distance, wind, arrow fletching, and gravity all affect drop. Faster arrows (higher draw weight, lighter arrows) have less drop at the same distance.
