The Case Air features an integrated hot shoe mount for using on your camera. If you’re mounting a flash or trigger on the hot shoe simply add a RapidMount Accessory Extension Bar to your hot shoe. Then, you can mount both the Case Air and flash/trigger on the bar. You would plug the Case Air into the USB as normal and then use a sync cord to plug your flash/trigger into your camera’s sync port. To learn more , visit How to Mount the Case Air to Your Camera.
