[QUOTE="FearNoWind, post: 1088047, member: 50867"] The Competition Electronics Pro Chronograph is a common open V style design which can be obstinate even under ideal circumstances. That design is sensitive to the distance the machine is from the muzzle, how level it is (actually how well it matches the bullet path so that the bullet is nearly the same distance from the detector at one end as it is when it passes the other end), whether it's cloudy or bright (to varying degrees, either atmospheric condition can have an effect on the device's accuracy), etc. If your fired round runs too high in the V it may not register at all. If the fired round is not perfectly aligned between the outer adges of the detection elements it is unlikely to register. If it doesn't run true to the surface of the chrono (same height over the first and second detectors) the output may prove to be inaccurate or unrecorded. Try setting it up about ten feet in front of the bench. Use a laser level or similar instrument to make certain the chrono is centered on the bullets path and a level to get the chrono on the same plane as the bullets path. Don't get too risky, but try to get the bullets path as close to the detector elements as possible without risking hitting the machine. Factor in recoil for that calculation. See if you can find a MagnetoSpeed for a test run. You may discover you like it better and finding a buyer for the Pro Chrono shouldn't be that difficult. Best of luck to ya .............. [/QUOTE]
