Thread: Chronographs what do you use ?

CED's IR Upgrade includes 4 support legs, 2 tops with LED's and 16 IR diodes each, a "Y" cable and an AC to DC power converter. The IR tops look nearly the same as standard skyscreens. Two of the four side supports have wire leads, contacts and power jacks molded into the plastic. Wires do not hang down inside the screens live area so they can be hit with a bullet! An NiMH battery pack with 8 hour rating and charger is available for total portability.
