SSR systems let you fire your slaved strobes without triggering flash. No need to hook up a PC cord to the main flash or use a camera-mounted strobe; the SSR transmitter replaces them both. Mount the compact transmitter on your hot shoe, or connect it to the camera PC terminal; each time you shoot, the SSR transmitter fills the studio with an invisible pulse of light.
Note:This is a transmitter only. A receiver is required (W930015 or W930010), or order this item as a system (W920125 or W920175).
