In this Electronics video you will see how to set up the Pocketwizard with a Nikon SB-800 and SB-900. When you use Pocketwizard as a master to trigger the flash, the remote flashes for a working distance of 1600 feet as against 33 feet. First attach a Pocketwizard unit to the flash by using the Velcro stickers. Plug in the cable supplied with the Pocketwizard in the 'Flash' slot. Open the rubber door on SB-800 and plug in the other end of the cord into 'sync'. Turn it ON. When the connection is properly connected, it will fire the flash. Watch the video for further instructions.
