Its 4-channel design makes it not only reliable and easy to operate but also allows the control of which strobes to fire without the concern of others who may be operating a similar radio on the same frequency. Its low voltage is safe for digital cameras.

The transmitter, powered by a 23A 12-volt pre-installed battery, has a standard hot shoe mount that can be mounted on the camera's hot shoe. It also has a standard PC connection for cameras connecting with PC cords. The PC connection is especially helpful for use with a flash meter.
