Archery & Bow Hunting
The large side surface area of an arrow makes it far more subject to wind drift than other hunting projectiles. Even 5-10 MPH of crosswind requires wind compensation or arrow selection adjustment. You can drop tufts of grass to estimate the wind - or measure the wind speed to +/- 3% accuracy with a Kestrel. The Kestrel even calculates the exact crosswind effect with respect to a target direction - invaluable when practicing and learning how to read the wind.
