This Godox X1 trigger set includes an X1T transmitter and a X1R receiver, both for Nikon. You can use this setup for off-camera TTL flash with any compatible Nikon Speedlight (not included), or with radio-enabled Godox strobes (also not included). Don’t care about flash? The receiver can also be used to trigger your camera with the included 10-pin, DC2, and miniplug-style remote connectors. In excellent condition.
