iTTL Hot shoe 3 way splitter cord
I am looking at ganging up 3 or more Speedlites on a FourSquare or similar to trigger off camera with a single wireless trigger. Rather than using 3 triggers, one on each flash I want use one trigger and then use a iTTL Hot Shoe 'splitter' cord to fire the other 2 speedlites.
ie. I need an iTTL Host Shoe cord that has 3 hot shoe heads all wired together.
Does this exist?
