Before testing, look what the FX radar has specification. You can try use devices at the same time, if frequencies are different. Labradar (FMCW technology) and digitally controlled 24 GHz adjustable frequency with 8 MHz channel step. .

@ Low price only with Arduino + HB100 Doppler radar sensor 😉, but the device with HB100 will be unreliable for a high speed measurement. Jeremy Lee https://www.allaboutcircuits.com/news/teardown-tuesday-hb100-doppler-radar-module/ https://youtu.be/0oK-Co2i01U HenrikL15...

A nice presentation... but if the distance Y of the barrel is higher, an error is higher too. https://youtu.be/1Mae7F3UuYI When the XN ( max. operating distance) is short, a frequency of received signal, strongly depends on an angle. An example 1 (Air Force Texan, assumed X...

What is BC new X system? Is it higher than below ? https://hardairmagazine.com/ballistic-coefficients My the Daystate Red Wolf .177, JSB Heavy has 0.035 at 12 Ft/Lbs.

@ I'm sorry if I wrote something bad. The results are approximately similar because they are two different devices and different measurement methods. 1) Small devices are sensitive to an angle. 2) If the distance from the barrel is too small - a noise, vibrations, may disturb the measurement...

It is not easy, but i can to describe soon - how to change the power ( up/down ) in the Pulsar and Red Wolf. The new design with front panel and circuit for programming ( USA version ).

I will give you today 1000 USD if their accuracy is true...

The Doppler needs a good stability microwave oscillator and antenna. The Labradar is Doppler chronograph - rest are marketing toys.
