With the optional Flash Confirmation Sensor attached to a
PocketWizard MultiMax set for receiver mode, the PocketWizard
MultiMax (set for Transmitter mode), receives a visual and audible
confirmation signal, when a triggered flash actual fires. The
confirmation system reassures the photographer at the camera
position that everything is working correctly. The Flash Confirmation
sensor included a narrow field of view flash sensor, mounting hardware
for popular electronic flash units and a 3-foot cable.
