The ProTwin is an amazingly versatile single head with two plugs and two flash tubes. It allows you to connect both plugs to one pack and halve the flash duration or to connect each plug to separate packs to get twice as much power and twice as fast recycling time And when you connect it to a Pro-10 or D4 you get the utmost from your pack. The ProTwin is as compact and durable as the ProHead Plus. It is compatible with more than 120 Profoto light shaping tools and designed to support the Profoto zoom function. It’s a unique feature that allows you to shape light by simply sliding the reflector back and forth on the head.
