Quick Start (5 steps)

2. Zero: Leave TRUE at ZERO unless you dialed/held at zero.
3. Ladder: Shoot 200, 300, 400… Enter observed TRUE; review updated TRY.
4. Hygiene: Single-decimal outputs; negative = down; check units first if results look off.
Weather
1. Tap Get Weather + Lock Heading, allow location.
2. Review Temp, Wind, Baro, RH, Elev, Station, GPS, Density Altitude.
3. Compass: Heading is muzzle; Wind From is source direction.
4. Optional: Include Spin Drift.
Advanced
Manual Wind Speed / FROM (0–360°): override station data.
Calibrate Wind (K / “MPH rifle”): match observed hold → model; shows as MPH Rifle: X.XX (Calibrated).
