Second Curtain 
Sync Mode

The Vello FreeWave Aviator supports 
Hi-Speed Sync (HSS) up to 1/8000 of 
a second on compatible cameras and 
TTL flashes. This means that the entire 
duration of the shot, including the flash, 
can be as short as 1/8000 of a second.
The FreeWave Aviator also supports 
second-curtain sync mode on 
compatible cameras and TTL flashes.
Consult your camera’s user manual to 
find out how to activate these modes.
