The SYK-4 flash remote controller is harnessing optical theory making the master flasher to control remotely the auxiliary one to flash synchronously without the need of connecting wires. It features small in volume, good-looking in exterior, high inflexibility and stable in performance, it can also artificially create different kinds of effect and take special photos._x000D_

Technical Performance:_x000D_
Distance of remote control: L = master flasher guide number/2 (The above formula will be established when the face receiving the light of the flash remote controller is aiming mutually at the illuminating face of the signal flasher and when the two are on a same level)
