Sight tape generator
Enter your bow setup and the wheel positions you measured at known yardages. The tool fits a real trajectory through those marks and prints a tape at exact 1:1 scale.
Single-pin movable sights (HHA Optimizer, Spot Hogg Fast Eddie, Black Gold Ascent, Axcel Landslyde) need a printed tape that maps wheel travel to yardage. Chrono speed alone isn't accurate enough — drag depends on your shaft, fletching, point weight, and air density. This tool calibrates against your actual zeroed pin marks instead, so the tape is right for your specific bow and arrow.
Enter at least two calibration marks (20 yd and 60 yd is a good baseline; three marks unlocks a quadratic fit). The tool prints at exactly 1:1 scale with a 1-inch verify ruler so you can confirm your printer didn't auto-scale. Setup tape with 1/8-inch tick marks is included for sights that don't have an etched scale.
