CED M2 Chronograph System Review:
CED (Competitive Edge Dynamics) M2 Chronograph is an exceptional chronograph. It has an operating range from 50 fps to 7000 fps, covering essentially all load speeds. It can store a shot strong of up to 500 velocities per string and up to 500 different strings (250,000 total shots). The standard M2 set sells for $200 and includes: Main CPU Unit with keypad, two Sensors, Daylight Sun diffuser screens, 2 ft. mounting bracket, USB cable, Data Collector software, and instruction manual. Youíll need a tripod or something to mount the measuring device to as well as a 9 volt battery for the CPU/main unit.
Recently, I tested the CED M2 chronograph. Although it was intimidating intiially, setting up and using the CED M2 was much easier than I thought. After installing the measuring devise, I placed it on top of the tripod and set it about 11 feet away from the muzzle of the rifle (the manual recommends between 8-14 feet), placing the anicipated path of the bullet in the middle of the devise. After hooking up the two chords to the CPU and turning it on, I was ready to fire. Using my .22-250 and Winchesterís 45 grain JPH, I fired 25 shots through the chronograph. Although Winchester has a published velocity of 4,000 fps, I averaged 3,898fps (removing the top & bottom shots) and only 2 shots reached a velocity of over 4,000 fps; these loads were more consistent around 3,900 fps.
A chronograph is an exceptional tool for reloaders, but is also a great tool for those who want to improve their downrage accuracy. The CED M2 is quick and easy to set up and is a fun, informational addition to any range shoot.
Below are some pictures from my test:
