The Wein Sync-Link Universal IR Flash Trigger can be used to trigger any flash unit that features a built-in optical slave. The Sync-Link simply slips into the hot shoe of a camera. An infrared signal is sent from the trigger to the infrared slave built-into the strobe unit to fire the flash.
The Sync-Link is ideal for use in studio settings since it uses IR, which requires line-of-sight with the flash. it can be used to increase the range of the built-in slave sensor of the flash.
Built-in regulator increases battery life substantially, and cycles to zero when not fired. It cuts off after the system is charged for the next flash.
Built-in Safe-Sync feature keeps your camera protected to a safe voltage level.
