Profoto Air Remote Transceiver
The Hensel Profoto Air Remote is a radio slave transceiver designed to work with the Pro 8a 1200 and 2400 Ws power packs, D1 Air series of monoheads and Hensel power packs and flash heads with built-in Profoto Air Remote technology. This transceiver can control an unlimited number of power packs and heads on eight channels. It can mount to your camera's hot shoe, or sync to your flash terminal for firing.
Operating from two AAA batteries, 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. Its triggering speed is over 100 fps.
The Air Remote can also be used in pairs or in conjunction with the Profoto Air Sync (one on camera and one on flash) to trigger flash units without built-in Air technology.
