This is a set of 2, 4-channel radio slave tranceivers with accessories, designed for use with Bowens or other monolights or AC Strobe power packs.

Radio slaves are more dependable than infared, or optical slaves. They operate on specific radio frequencies that are more immune to interference and failure. An additional studio slide-switch provides additional protection from other photographers' triggering of radio slaves.

These tranceivers may be used as a transmitter, or receiver, by flicking a switch. Includes AAA batteries.
