BULLETSEEKER mach4 for speeds up to 1200 m/s 4000 fps BULLETSEEKER 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. All made in Europe May 22 2 Instructions BS HS engl final 21-april-2022.docx The core components, the 120 GHz radar chip and the beamforming lens, empower us to generate the biggest radar cross section of bullets and pellets on the market. This results in an extremely high accuracy and with a lot of detections in the first meter. The BULLETSEEKER mach4 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. Chronometers with light barriers have 2 measuring points only. The BULLETSEEKER mach4 has 20 to 1000 measuring points. We are measuring up to 1000 detections with very high precision. The typical mistake of light barrier systems is the gun position and the firing angle as well as problems with light conditions. This is solved by the BULLETSEEKER mach4 due to the radar technology, the small size, its light weight and the ability to mount it on the gun like a flashlight. Enjoy accuracy, enjoy BULLETSEEKER May 22 3 Instructions BS HS engl final 21-april-2022.docx On / Off
- Press the switch for a second

- a Picatinny rail counterpart is mounted on the BULLETSEEKER
- a universal V-holder is part of the delivery
it can be attached to the barrel with an elastic band or stand alone beside the gun May 22 5 Instructions BS HS engl final 21-april-2022.docx Positioning
- Beware of radar shadow
- Closer to the muzzle is better
- Find the right position on your gun by testing
- Beam forming is set to 22 degrees mid of the lens
- Do not cover the lens and the aluminium foam filter May 22 6 Instructions BS HS engl final 21-april-2022.docx Picture by Michael Andrew Photography Positioning BULLETSEEKER mach4 Explosive ammunition creates a muzzle cloud from hot gases and metallic abrasion. This cloud of plasma and metal splinters is electrically conductive. It can interfere with the radar waves and wipe out the signal. We have tested different muzzle brakes. Muzzle brakes with a guided gas jet such as star or spiral shape allow the radar signals to pass through very well. Find the right position on your gun by testing. May 22 7 Instructions BS HS engl final 21-april-2022.docx Data processing
- Data processing is fully automatic
- All data can be saved to your mobile phone and processed by yourself as well
- Data are saved in the folder DOWNLOADS with the file name BS + time stamp as a .log file, readable with a text editor
- The file name is a proposal only, you can rename it
- The angle between BULLETSEEKER and muzzle is important and falsifies the results of the first 3-10 detections (first 10 cm) per shot
- The initial speed is measured in the first meter
- You can evaluate and correct the data. In the app you can manage the data by scrolling with your finger tip May 22 8 Instructions BS HS engl final 21-april-2022.docx Application BULLETSEEKER mach4 Android 9 and higher
