This optical slave is packaged in a convenient hotshoe.
This device will immediately fire a connected flash unit when another flash burst is detected. This allows a remote flash to be fired without any connecting wires.
It requires no batteries or other power; it runs off the flash unit to which it is connected.
The triggering flash must not emit a pre-flash as this will prematurely fire the connected flash.
This optical slave will work with many hotshoe based flash units (see very partial listing below).
