Designed to be used with a Hensel flash head incorporating the FREEMASK technology, the Hensel Strobe Wizard Plus - Transmitter FREEMASK triggers the head wirelessly, and automatically alters the flash output in sequential exposures for creating a cut-out mask. For added versatility, you can use this device like the standard Strobe Wizard Plus transmitter in order to wirelessly trigger Expert or Integra series flash heads with inbuilt receivers. Furthermore, there is the option of switching between full, off, and prop for controlling the flash power and modeling lamp. This transmitter runs on a single 6-V battery with a life cycle of 1–2 years.
