The Hensel Profoto Air Sync is an eight channel radio slave transceiver designed to trigger the Profoto Pro 8a series, D1 Air monolights and Hensel heads and packs that offer built-in Profoto radio remote technology. Heads and packs without built-in radio slaves can also be triggered by simply adding another Air Sync to them to act as a receiver.
The Air Sync mounts directly onto a camera hotshoe or to the PC outlet on the power pack or flash head via the appropriate optional cables. Operating with two AAA batteries (not included), at a frequency of 2.4GHz, the Air Sync has a range of 1000' (300 m). It can sync up to 1/250 second with a focal plane shutter camera, and 1/500 second with a leaf shutter camera.
Note:Not compatible with the Pocket Wizard system
