Mount a shoe-mount flash onto this unit, then mount it to a light stand, and fire it from the flash on your camera, instantaneously, without wires. Create more 3-dimensional lighting with multiple flash units quickly, and conveniently.
I was able to easily put an old Vivitar 285 flash to good use as auxilliary lighting for indoor sports pix by simply attaching the slave/flash combo directly atop a light stand. The biggest drawback is that almost all of my stands have a 1/4 stud rather than the 1/8 that fits this slave.
works perfectly well on indoor shooting, I have yet to test it outdoors
