Clark County Gun Club Installs NEW Chronograph Technology That Uses Doppler Radar
Since assuming operations of The English Pit Shooting Range we have tried to provide our visitors the best equipment that we can find (and afford). Chronographs are one of those shooting accessories that we have provided on a no-charge basis.
For those unfamiliar with them, a chronograph measures projectile speed at a fixed distance from the muzzle. This data is particularly useful to those who reload their own ammunition and long distance shooters. Combining the projectile speed with other physical and environmental factors, the projectile's trajectory, speed, power factor, etc. can be calculated for any distance.
Today's typical chronograph relies on the projectile passing over two optical sensors. The shadow of the projectile starts and stops a counter which is the basis for the speed calculation. This requires ideal lighting and that the projectile pass very close to the sensors. If the person firing the projectile is not careful it can strike the chronograph. Since a chronograph is typically set up only 10 to 15 yards in front of the muzzle, a bullet strike can cause significant damage making it useless until replacement parts are installed. This has repeatedly happened to ours.
A new generation of chronographs use Doppler radar to track and measure projectile speed. Chronographs using Doppler radar are immune to the many shortcomings of optically triggered chronographs. See the comparison of Optical vs. Doppler below.
We've replaced our problematic optical technology with state-of-the-art Doppler radar! We are excited for you to give our new Doppler radar chronographs a spin!
