The PocketWizard Plus II Transceiver/Relay is a triggering system that offers Auto-Sensing Transceiver Technology. This technology analyzes the status of the Plus II's miniphone jacks, camera hot shoe or the TEST button to determine which mode (Transmit or Receive) to set itself. By default, the Plus II is always in Receiver mode unless it senses a trigger pulse from a camera's hot shoe. It then quickly switches to Transmitter mode. The Auto-Sensing feature can also be disabled, if necessary.
This unit can also be used as a relay. You can remotely trigger your camera, and the camera-mounted transceiver automatically relays the triggering signal to a remote flash. With the Plus II's fast switching speed, there's no loss of camera shutter speed performance or triggering delays.
Note: Our PocketWizard radio devices operate on the U.S. frequency of 344MHz. PocketWizard radio devices operating on one frequency cannot operate with PocketWizard devices on a different radio frequency. PocketWizard will not ship devices to markets that use a different frequency and cannot provide proper warranty service for products shipped out of their intended market.
