B1 500 AirTTL To-Go Kit

Off-camera flash. With TTL. Without cords.

The B1 makes it easy to take the flash off your camera, take control and shape light.

With TTL you set the light in a flash. With HSS you control the ambient light no matter how harsh the sun is. With battery-power and a clever design without cables or cords, you can take the B1 with you wherever you go and put it wherever you want.

Add to that the power, speed and light shaping possibilities that Profoto lights are known for, and you have an off-camera flash that makes great light easy.
