Create beautiful lighting and take advantage of your shoe-mounted flash's true potential with the FreeWave Aviator Wireless Flash Trigger Transceiver from Vello. Dedicated to Canon's E-TTL II system, users will have full functionality with modern automatic flash settings. This transceiver is also able to function as either a master transmitter/trigger or a slave receiver for maximum versatility. Operation is reliable as well due to the Aviator's use of a 2.4 GHz radio frequency to provide a range of up to 300' without the need for line-of-sight.

The Aviator Transceiver has access to 16 different channels, ensuring limited interference with other users and the wireless technology set up in your venue. Users will also have access to 3 different groups with which to organize their flashes (A, B, C). The group controls of the Aviator allow for separate adjustment of the flashes in either TTL or manual modes as well as the ability to set group ratios in A:B or A:BC configurations.

Setting up the Aviator is simple as it easily slides into your camera's hot shoe to receive TTL information and also offers top hot shoe for adding another flash to the mix. For ease of use, all information is accessible via a backlit LCD screen and it has a standard 3.5mm sync port. Also, it has high-speed sync and a mini-USB port for firmware updates. It runs on two AA batteries.  not included
