Triggering bowens and nikon sb910
I've just bought the bowens kit Gemini pro500
(it's my first studio flash) and I'm gonna use as a third 'head' my nikon sb910.
The kit includes pulsar transmitter and one pulsarcard trigger ,how can I trigger the bowens flash and nikon off camera in ttl mode ?do I have to buy another card for the second head? Shall I use a sync cord?
