Susan,
While some flash units (mainly monolights?) have slaves built in, most
slaves are discrete units. Note that the slaves themselves don't provide
the light -- they simply trigger a flash that you've attached to them.
They generally consist of a light-sensitive mechanism (the propeller heads
on the list will provide deep detail here, I'm sure! <g>) and either a hot
shoe or a PC cord connection or both. My slaves are the dual kind -- hot
shoe connection on top and a PC cord connector on the side.
No batteries required for the slave.
Beware, however -- on some of the cheaper slaves (i.e. Wein) the "slots" on
the hot shoe are very narrow and most flashes (i.e. my T20) won't slide in.
Take one of your flashes with you when purchasing slaves.
HTH --
Dave
