Add wireless enhancement to your flash's capabilities with the Phottix Ares II Flash Trigger Receiver. The receiver features both a hot shoe and a 3.5mm sync port for connecting to both on-camera flashes and studio strobes. Once connected, this receiver can then be triggered by a separately available Ares II transmitter from a distance of up to 492'. This system also uses a 2.4 GHz frequency to limit interference as well as access to 16 channels, 4 groups, and digital ID codes so that it won't be accidentally tripped by nearby photographers.
