How this works
Angle correction uses the Rifleman's Rule: gravity acts on the horizontal component of the shot, so you dial the horizontal distance on your sight — not the line-of-sight distance. A 50-yard uphill or downhill shot at 30° dials like a 43-yard flat shot.

Wind hold is the lateral offset in inches you need to hold into the wind to compensate for drift. Hold your sight pin that many inches upwind of the target.
