Speed Tracker air

Read full description

SPEEDTRACKER air is an amazing piece of technology. Developed by a team of German and Czech Engineers. Case design in the Netherlands, mathematics and programming in Berlin and Prague. Tested by gunners in the Czech Republic , Italy, Canada and the UK. The radar beam formed by incredible lenses with an aluminium foam filter (patented) in Bohemia. The heart is a 120 GHz radar SiR-chip – made in Germany. These wavelength empower us to generate the biggest radar cross section of bullets on the market. This results in an extremely high accuracy and with a lot of detections in the first meter. The BULLETSEEKER air is detecting the bullet up 1000 times in the first 100 cm. This is the true muzzle speed and it is not affected much by wind and air pressure. The reason for this is the very short wavelength of only 2.5 mm - competitors are using 10 times longer radar waves. Certified with CE and FCC.

FieldSolve is a fast, accurate ballistic calculator built for long range shooters, hunters, and precision rifle competitors who need a firing solution they can trust on the first shot. Enter your rifle, load, and conditions and FieldSolve solves the full trajectory — bullet drop, windage, and the exact hold or dial in MOA or mils. BALLISTIC SOLVER A precision ballistic engine that accounts for muzzle velocity, ballistic coefficient (G1/G7), zero range, sight height, shooting angle, spin drift, aerodynamic jump, and Coriolis. Get your holdover and windage instantly, as a dialed solution or a reticle hold. BUILT FOR THE FIELD Save unlimited rifle and load profiles. Build range cards and DOPE charts for every distance. A clean heads-up display gives you the numbers you need at a glance, even on the clock. LIVE ENVIRONMENTAL DATA Wind, temperature, pressure, humidity, and density altitude all change your solution. Enter them by hand, or connect a weather meter to pull live atmospherics straight into your solve. Connect an anti-cant level to read your rifle's true cant, and import muzzle velocity directly from your chronograph so your data is real, not estimated. RECORD YOURSELF SHOOTING FieldSolve records video of your shot with a live data overlay — your solution, wind, cant, and velocity burned right onto the clip. Review your form, confirm your DOPE, and share your best shots. FEATURES - Advanced ballistic solver with G1 and G7 drag models - Bullet drop, windage, and lead in MOA, mils, or clicks - Spin drift, aerodynamic jump, and Coriolis - Unlimited rifle and load profiles - Range cards and DOPE charts - Angle (cosine) and cant correction - Metric and imperial units - Live weather, level, and chronograph integration - Video recording with data overlay FieldSolve is a free ballistic calculator. Whether you shoot PRS, NRL, F-class, or hunt at distance, it gives you a firing solution you can rely on. Always follow safe shooting practices and know your target and what lies beyond it. Ballistic solutions are calculated estimates; confirm your come-ups on paper before relying on them in the field.
