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 coiled, stretches to 3', and will trigger Mamiya RZ67 and 645 Pro-TL cameras.
