Looking for a dedicated system for triggering your flashes? This is the setup for you. This kit consists of one transmitter and one receiver. You can now fire your strobes from as far as 100 feet away cable free. You cant always get those strobes to fire with optical slaves. Sometimes other cameras can set them off too. With this kit those worries are a thing of the past. With a dedicated frequency you can count on your strobes firing when they are needed. Great for the studio or on location where you need maximum mobility.
