The application provides you a full ballistic solver for your air rifle and pellet, then lets you practice 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
• Wind Table: wind drift at every distance, read straight off your reticle marks
• HFT Dope Card: a holdover card for your own reticle, ready to print or share
• Field calibration for scope height, BC and speed, and your scope click value
• Measure ballistic coefficient from two chronograph readings

WIND, THE PART THAT TAKES YEARS
• Live gusting wind that keeps changing while you aim
• Windicator and flag give you the same partial clues as a real course
• Wind Observation: watch a lane and see the correct hold appear on the reticle
• Windicator trainer: record your own thread angle to wind speed table
• Wind Quiz: wind problems generated from your own rifle and pellet
• Bluetooth anemometer support for live field conditions

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

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
