The FreeWave Fusion Wireless Flash Trigger & Remote Control from Vello is a versatile, reliable remote control kit that will trigger off-camera flash units and studio lights from up to 300 feet away. It can be used to configure up to three different light groups, which can be triggered individually or simultaneously, for a total of seven different combinations, using its multiple groups feature. Simultaneous triggering of multiple light groups requires additional FreeWave Fusion Receivers (available separately).
The FreeWave Fusion also provides the convenience of a wireless camera shutter release, ideal for photographing wildlife, and also for macro and close-up photos or long exposures, where the slightest camera movement can ruin a picture. Working on the 2.4 GHz frequency gives you reduced radio interference and an extended range (up to 320' / 100m)—you don't need to have line-of-sight alignment, either, as radio waves will pass through walls, windows and floors.
