Used Profoto Pro-B4 1000 Air Generator

The Profoto Pro-B4 1000 Air Generator is the fastest, toughest, most precise battery generator on the market. At lower power settings, it fires up to 30 flashes per second, while the recycling time on full power is less than a second. In other words, you never have to wait for the Pro-B4. Now how fast you can shoot depends only on your camera. With flash durations down to 1/25,000s, the Pro-B4 offers the shortest flash durations of any generator on the market. It is now possible to freeze motion in a way that was not possible before.

The solid-cast aluminum chassis and the sturdy rubber frame ensure that the Pro-B4 can take a beating. All connections are covered with protective lids, helping to prevent moisture and dust from entering the generator. On-location, its performance rivals that of any AC-powered studio generator. In the studio it gets even better. The battery can fully recharge in less than 45 minutes and can be recharged while in use. This means that the pack can be used continuously, all day long - even with moderate modeling light use.

The Pro-B4 offers a huge 11 f-stop power range with unrivaled stability in power output and color temperature. It has two independent outlets with individual and intuitive controls and displays. The unique Air system is the fastest radio sync system in the world. Control the Pro-B4 from your camera, your computer or from the palm of your hand.
