Pact Professional Chronograph XP
September 24, 2010
Uneven natural lighting conditions or artificial lights like you find on indoor ranges can cause erroneous velocity readings.
PACT has developed a solution to these problems with its new Professional Chronograph XP. This unit will work with natural light just like a traditional chronograph or with infrared in dim light--or even in the dark. Beyond the usual velocity and standard deviation calculations, it will also produce bullet drop, IPSC power factor, kinetic energy, momentum figures and more.
It has the ballistic coefficient for more than 800 bullets stored in memory, or you can compute your own ballistic coefficient for any bullet. Additional data inputs include temperature, altitude and bore-to-sight height. Data can be downloaded directly to your computer.
This is a versatile unit and proved to be just as accurate under artificial lights or in the dark as it was outdoors. It didn't matter whether I was testing high velocity .223 Remington or .45 ACP that lumbered across the sky screens at 900 fps--the chronograph worked perfectly. $270. www.pact.com, 800-722-8462
