This RadioPopper Radio Receiver for Einstein 640 Flash Head plugs into the body of the Paul C. Buff Einstein 640 allowing triggering of the flash from distances up to 1,750'. The receiver works with virtually all RadioPopper systems and requires an optional Jr2, PX, JrX or Nano transmitter for use. In addition to remote triggering, the optional Jr2 transmitter is also capable of controlling the Einstein's power levels. Since the receiver draws its power from the flash head, no batteries are needed.
