The Bowens Omnicell Slave Unit is a slave sensor with a 1/4" phone plug. It is ideal for those situations where the built-in photocells on the monolights just do not receive enough light to trigger the flash. The simplest solution is to plug an extension sync lead into the flash and fit an auxiliary Omnicell into the other end of the extension. The Omnicell is placed in a position where it can "see" the master flash.
