The PlusX is the simplest PocketWizard radio ever and the perfect entry into the PocketWizard Wireless System. How simple? Attach one PlusX to your camera, another PlusX to a remote flash using an included cable, set both radios to the same channel and start taking pictures. The PlusX is compatible with all Standard Channel-capable PocketWizard transmitters and receivers, so it’s the perfect companion for your existing radios and new flashes. The PlusX radio uses our Legacy firmware.
