Set of two PocketWizard PluxX transceivers. The same range and reliability as the other PocketWizard professional triggers in an easy-to-use entry-level package. The PlusX transceiver is based on the Plus III, but has 10 channels, selectable via a permanently-backlit dial, and controls a single rather than mutliple groups. It automatically senses whether it needs to operate as a transmitter or receiver and uses the 433MHz frequency to reliably trigger flashguns or cameras up to 500m away. It can be used with other PocketWizard transmitters, and as a relay transmitter to extend operating range. Robust and reliable, it is powered by 2 x AA batteries.
