The Quantum QF9C Qflash PILOT provides all the features of the TRIO without the flash head. With built-in FreeXwire TTL radio and QTTL adapter for your digital camera you control an unlimited number of remote Qflashes. Slip it onto the camera hot-shoe and go, it"s self powered. Or connect a Turbo with the included long power cable CQ2 or the accessory short power cable CCQ8. PILOT"s radio sends TTL commands to remote Qflash TRIO"s or Qflash 5dR series flashes. Configure distinct modes and settings of remote Qflashes from the on-camera PILOT. Radio QTTL signals from PILOT do not require line-of-site like camera optical links. They"re more reliable and work at 5 times the distance.
