West Cobb Archery Ballistics
Dual-mode precision sight-tape calculator
Generate a trajectory-based starting tape or build directly from measured marks. Verify all predicted tapes before hunting.
Predicted setup
Important: wheel diameter does not fully describe a slider sight's gearing. Use the movement ratio to calibrate predicted sight movement to physical tape travel with a known long-distance mark.
Verified marks
Measure from the center of the zero mark to each known tape mark in millimeters.
