This AC powered radio trigger kit made by high quality plastic, will work with all flash units, digital cameras and light meters up to 40 meters.
Because it uses radio transmission, rather than IR, it allows for triggering around corners, through walls and is not affected by high ambient light situations. The transmitter is equipped with a hot shoe for on-camera mounting and a PC cord for cameras without a hot shoe. It is powered by a 12-volt battery. Because of its low-voltage operation, it is perfect for digital cameras.
The receiver has a PC sync outlet and a standard photo-jack plug(6.35mm) that can be reduced to 3.5mm with the supplied jack adapter. It can be attached to the flash unit and get the power from the power cord.
