Pocket Wizard Motor Drive Cords connect to your 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 all "D" Series DSLR's, 1, 1V, 1VHS, 3 Film SLR's.
For this cable without the pre-trigger feature, order #804-501.
