The Impact PowerSync16 DC Radio Slave System is designed for triggering flash units and cameras up to 590' (180 m) away indoors, or 200' (60 m) outdoors using the included battery-operated transmitter and receiver.
PowerSync16 has 16 digitally coded channels available so you can even work at events with other photographers without flash or radio interference. You can trigger as many flashes or cameras as you like from one transmitter, as long as they're all on the same frequency and have this PowerSync16 DC or optional AC receiver. Flash sync speeds of up to 1/250 second are possible with PowerSync16.
The transmitter operates on one 3V CR2450 battery, and the receiver uses 2x AA batteries (included). Included in the kit are a mini to mini cable, a mini to phono adapter, and a submini to pc cable. Impact offers a selection of other compatible sync cables and camera release cables as well. The PowerSync16 system is not designed to perform in TTL mode with flash units - camera and flash must be set to Manual Mode.
