Calumet Quad Plus 2.4GHz Wireless Receiver for Canon Flash Systems

The Quad Plus enables you to assign your flashes to four groups so that you can either isolate or combine different groups to allow for complex lighting setups. The trigger's 4 channels can be used so that up to 4 different photographers can shoot with the Quad Plus in the same location without triggering each other's flashes. (Flashgun not incuded - for illustration purposes only)
