Satechi (3 feet) CM-N3-P Compatible Pre-Trigger Product Details
Motor drive cords connect to the camera's remote cable socket, and enable the Pocket Wizard radio slave 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 Canon N 3- Pin type cameras, such as EOS 3, 1V, 1V-HS, D2000, D30, D60, 1D Series, and 5D. Triggers any Canon camera that takes a Canon RS80N3 remote trigger cord.
