This Cybersync outfit includes one CST Transmitter and three CSRB receivers, plus PC sync and miniplug cables to connect the receivers to nearly any flash. The Cybersync is only nominally cyber, with a simple frequency dial and nothing else- but it’s an easy to use, reliable way to trigger strobes. The CST transmitter slips into any standard hot shoe; the CSRB receivers connect to strobes with a cable. Please note: the receivers do not have hot shoes, so your flash needs some way to accept a remote cable. Basically every studio strobe has this connection, but not all camera-mounted lights do, so check first. Includes three each of miniplug-miniplug, miniplug-1/4″, and miniplug-PC sync cables, plus a PC sync-trigger cable for systems without a hot shoe.
