A partnership between Hornady and Kestrel has resulted in the 5700 Ballistics Weather Meter with Hornady 4DOF. The platform combines onsite environmental measurements and Hornady's 4DOF trajectory solutions into a rugged and portable package. The latter previously available as a smartphone app, the 5700 Ballistics Weather Meter takes the phone out of the equation entirely by incorporating 4DOF into the weather meter, making it a one-stop solution for long-range shooters.
