560iv - 2 Light Kit - Canon
This is a setup with 2 of the 560IV speedlights as well as the 560-tx controller. This will allow you to have a great 2 light setup for all of your off camera flash needs. In the event that you ever need to have a flash ON camera, the 560iv can be used as a master flash to allow you to have it on camera and control your other 560IV or 560III speedlights off camera. Below is a video on how easy it is to use the controller with these lights.
