WindMaster is a ballistic calculator and wind reading trainer for precision airgun shooters. Elevation takes a few weeks to learn. Wind takes years. WindMaster gives you a full ballistic solver for your rifle and pellet, then lets you practise reading wind through a simulated scope whenever you cannot get to the range. BALLISTIC CALCULATOR • Pellet specific aerodynamic drag model, built for diabolo projectiles • Ballistic coefficient and muzzle velocity per profile, multiple rifle profiles • Full atmosphere: temperature, altitude, station or sea level pressure, humidity • Trajectory tables and graphs • Inclined shot solutions • Wind Areas: set different wind along the lane and see the path from above • POI Reticle: your live point of impact projected onto your own reticle • Field calibration for scope height, BC and speed, and your scope click value REAL SCOPES AND RETICLES • Over 20 reticles taken from real scopes, including Sightron, Schmidt & Bender, Falcon, Element, Optisan, Delta, Nikko Stirling, Hawke, Valiant and Bushnell • Correct magnification and true second focal plane behaviour • Elevation turret with clicks and turns, using your own click value WIND • Live gusting wind that keeps changing while you aim • Windicator and flag give you the same partial clues as a real course • Windicator trainer: record your own thread angle to wind speed table • Bluetooth anemometer support for live field conditions PRACTICE AND SIMULATION • Field Target: 9 to 50 m, knockdown silhouettes and kill zones, three levels • Hunting Field Target: forced stances and inclined lanes • Bench Rest: the official 25 box card at 25 or 50 m, regulation scoring with X count tiebreak • Free practice, plus long range out to 300 m • Online multiplayer: every shooter faces the same seeded course, with live rival progress TRAINING LOG • Record real range sessions, hit or miss per shot, notes and photos • Conditions captured with the session • Export and import your whole log Free to download.
