Godox X2 Trigger (Canon)

Excellent, small wireless flash trigger for Godox strobe lighting systems. Works with AD range of monolights (AD400/600). 

Features passthrough hotshoe on top for adding additional on-camera flash if required. 

Also features Bluetooth app which connects to the trigger allowing remote adjustment of the strobe power and settings. This works great if your digi-op needs to adjust settings on the fly while the photographer remains focused on working with their talent.
