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.
