The PocketWizard PlusX 2 Pack Kit was put together by B&H to provide a wireless solution to triggering a studio or portable flash unit remotely at distances up to 1,600'. It's also possible, using one transceiver on-camera and the other acting as a receiver on your remote flash, to trigger multiple flashes positioned near the receiver using their onboard optical slaves.
The PlusX Transceiver offers 10 channels that are easily navigated via the large backlit channel dial. Auto-Sensing technology allows it to instantly fluctuate between transmitter and receiver duties. The PlusX is fully backward-compatible with all other PocketWizard radios slaves and as well as flash units with built-in PocketWizard reception such as Sekonic, Photogenic, Norman, Bowens and Dynalite. Sync speeds as high as 1/250 second for focal plane shutters and 1/500 second for leaf shutters are possible with triggering speeds up to 14.5 frames per second. A hot shoe on the unit and a 3.5mm sync port allows connection to devices with or without hot shoes.
