The sync flash shoe to clip on, e.g., compact flash holders and panheads and similar accessories with flash shoe as well as photo and lamp tripods via a 1/4 inch thread. The photo cell on the front of the sync flash shoe receives the flash light from the master flash and triggers the flash that is clipped onto the sync flash shoe via the center contact.
The servo trigger, however, can only be used in a limited manner, as it can only be used for flash devices with high voltage firing circuits, such as those of older flash devices. It does not work with modern flash devices with a low voltage firing circuit, such as the Canon Speedlite 430 EX. For modern flash devices you can use our walimex Digital Flash Trigger.
