The Smith-Victor PG750 Optical Slave Trigger lets you trigger off camera flash units that do not have a built-in slave. This small, universal optical slave can be attached to a non-slaved flash unit via a standard sync cord.
When connected to a secondary flash, it "sees" that light, and fires the off camera flash it is connected to instantaneously.
It is also ideal for flashes with low sensitivety slaves. Only 1-1/8" long, and 7/8" in diameter, the PG750 is small and easy to position. It includes a suction cup for convenient mounting.

Reliable and just as simple as you can get. I returned, but only because I needed something with a pre-flash cancellation. Overall a nice simple product.
