Quantum Instruments FW10w FreeXwire Digital Transceiver

Each Quantum FW10w FreeXWire Digital Transceiver can be used as a radio transmitter or receiver, or relay unit. The FreeXWire creates a two-way link between the camera, flash, and photographer. One FreeXWire unit signals a remote FreeXWire to trigger a flash or camera, and the remote sends back confirmation that it received the signal.
