This Photoflex FlashFire Wireless Trigger is part of the FlashFire radio remote system which allows you to trigger your flash or studio strobe at distances up to 164' (50 m).
The beauty of the system is that it doesn't depend on "line-of-sight" communication between the transmitter and receiver. That means that you can trigger the flash through obstructions like walls, doors etc. Forget about that tangle of dangerous PC cords and potential damage to toppling equipment.
The 2.4 GHz FlashFire Wireless Trigger has 16 selectable channels to virtually eliminate interference or overlap with other photographers on the scene. It's not a battery vampire either. It runs on an easily-sourced CR2 (not included) with a battery life of approximately 20,000 flashes.
