This optical slave will work with the Vivitar 283 ⁄ 285 ⁄ 285HV, Sunpak 383 &frasl 544 ⁄ 555, Nikon SB-24 ⁄ 25 ⁄ 27 ⁄ 28 ⁄ 28DX, Canon 580 EXII* and many other flash units.  It has a female PC sync connector.

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 it is connected to.

It works with both small, battery-powered flash units and studio flash units.

Note that you must have some way to connect this optical slave to your flash unit. Many flash units come with a PC cord that will connect to this optical slave.

*This device will work with the Canon 580 EXII if connected via the PC port, but will not work with other Canon EX Flash units.  It will work with older Canon flash units including the Canon EZ series.

In addition, the triggering flash must not emit a pre-flash as this will prematurely fire the connected flash.

It is small, about ½ x ¾ x 1 inches.  The slave and circuitry is encased in solid resin, so it is extremely rugged.

Price: $8.00 + shipping
