Kestrel HUD Heads Up Display Manuals, Downloads, and Troubleshooting Documents
The free Kestrel LiNK Ballistics app is the perfect companion to the Kestrel Sportsman, Kestrel 5700 Ballistics Weather Meter, Kestrel 5700 Elite Weather Meter with Applied Ballistics, Kestrel 5700 Ballistics Weather Meter with Hornady 4DOF, or Kestrel 2700 Ballistics Weather Meter. Build and manage your gun/bullet profiles and download them to your Kestrel Ballistics Meter before you set out. At the range or match, secure your Kestrel Ballistics Meter to a tripod using the optional Kestrel Vane Mount and use the LiNK Ballistics app to quickly adjust the target range and direction of fire and view the shooting solution and wind rose without leaving your shooting position. It’s like having a meteorologist and ballistician standing next to you while you shoot.
Download Kestrel LiNK Ballistics for iOS:
LiNK (Kestrel)
Quick Look
- Wirelessly adjust the target range and/or direction of fire on your Kestrel and view the resulting elevation and windage solution without ever leaving your shooting position.
- Build and transfer custom gun/bullet profiles.
- Comprehensive Applied Ballistics bullet library provides G1/G7 ballistics coefficients, weight, diameter, and length data for over 500 bullets.
- Comprehensive Hornady Bullet Files that include the bullet's mass properties, aerodynamic moments, and Doppler Radar determined drag coefficients (Kestrel 5700 4DOF only)
- With Kestrel Elite Meters, also access and use Applied Ballistics Custom Drag Models, providing exact drag profiles for supersonic, transonic, and subsonic bullet flight for maximum accuracy at extreme long range.
- Advanced Target Card view allows you to simultaneously view the elevation and windage solution for up to 10 targets defined by direction, range, and angle - giving you the edge at precision rifle matches (available for Kestrel Elite only).
- Export your customized target card to save or print out.
- Use your phone's compass to capture a new direction of fire, wind direction, or inclination angle and send it to the Kestrel.
