SEAGULL SYK-3 Flash Remote Controller 

This Hot Shoe Flash Remote Slave Trigger has a sensor to sense light from the master flash so as to trigger the slave flash wireless.

1. Introduction
    The SYK-3 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.

2. Technical Performance
    1) Distance of remote control: L=master flasher index/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).
    2) Structure
    A flasher standard socket is seated at the top part with a fixed nut on the bottom surface.
