The Nissin Air System (NAS) is an easy-to-use radio transmitter system developed by Nissin Digital that allows photographers to control and trigger flashes remotely, with coverage up to 100 meters (328 feet), even around obstacles.

You can add NAS capability to a non-NAS flash using an Air R Receiver.
