This Paramount Nikon 4-Pin Pre-Trigger Motor Drive Cable is for Pocket Wizards or other wireless radio slaves with a 3.5mm miniphone jack and a Nikon D70S or D80 DSLR camera.
This pre-trigger cable connects to the camera's remote cable socket and enables your radio slave to trigger the camera's shutter remotely. This 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. This cable is approximately 3' long and will trigger the D70S and D80 DSLR cameras via the 4-pin remote socket. It will not work with the D70. The cable is made in the USA.
