Kestrel MeterKestrel® 5700 Ballistics Weather Meter with Hornady® 4DOF®

Kestrel® Ballistics has combined precise Hornady® trajectory solutions with its own onsite environmental measurements in the Kestrel® 5700 Ballistics Weather Meter with Hornady® 4DOF®.

Ideal for precise long-range calculations using select low drag precision bullets, the Hornady 4DOF® Ballistic Calculator provides trajectory solutions based on projectile drag coefficient (not ballistic coefficient) along with the exact physical modeling of the projectile and its mass and aerodynamic properties. Additionally, it calculates the vertical shift a bullet experiences as it encounters a crosswind, referred to as aerodynamic jump.

When paired with Kestrel’s environmental information, the result is extreme accuracy at long range with ultimate convenience in the field. Hunters and shooters can focus on their shot without fumbling with a smartphone or worrying about apps.

Key features include:

  • Accurate measurements of wind speed and direction, temperature, altitude and more.
  • In addition to 4DOF, a G1/G7 Ballistics Solver with large library of independently tested bullet data.
  • Easy operation with large buttons and bright, clear backlit display.
  • IP-67 waterproof, MIL-STD-810 drop-tested and backed by five-year warranty.
  • Powered by one AA lithium battery for hundreds of hours of reliable use.
  • Load-and-go convenience for calculating trajectories in areas without cell service.
