Metz Mecalux 11 Auto Hot Shoe Slave

The Metz Mecalux 11 is amongst the very best of purely optical slaves.  Like all optical slaves, it triggers an auxiliary flash from a main unit without a directly wired connection.  But the Mecalux 11 has a little more going for it.  Many slaves only feature a flash shoe, but the Mecalux 11 can be used with a hot shoe connector or a standard PC cord.  On the side of the unit there is a pc female socket, and on top there is a standard hot shoe connection.

Unlike most slaves which have both a hot shoe and a pc socket, the Mecalux 11 will simultaneously trigger flashes connected via its pc socket and its hot shoe-usually if one is enacted, the other is cancelled out.  The Mecalux 11's hot shoe rotates 360°, and the bottom features a "cold" flash shoe as well as both 1/4"-20 and 3/8"-16 threaded female sockets.
