Pocket Wizard Motor Drive Cords connect to the camera's remote cable socket, and enable your Pocket Wizard radio slave SET to trigger the camera's shutter remotely. This pre-trigger cable is designed to keep the camera constantly "awake", and has the same effect as holding the camera's trigger button pressed down half-way. A camera will trigger much faster in the "awake" mode, but will also use up more battery power. However, the pre-trigger mode can be switched on or off from the cable itself. This cable is 3' long and will trigger the Hasselblad H series, or Canon EOS cameras compatible with the RS-60E3 Remote Switch: Canon Digital Rebel series, Elan 7 series, Elan II, Rebel T2, Ti, 2000, G, X, XS, XSN & IX. For this cable without the pre-trigger feature, order #804-509.
