The Interfit Strobies Pro-Flash Transmitter & Receiver Kit is used to remotely trigger the Strobies Pro-Flash 180 and 360 Flashes. This kit includes a transmitter for the camera and a receiver for the flash that have a working range of up to 165' when necessary. Also, it features a maximum sync speed of 1/250 second.
The transmitter mounts on the camera's hot shoe and has 16 channels. This allows the programming and grouping of up to 16 Pro-Flash units. Additionally, you have the power to adjust the power, set the AF-assist beam and audio signal, as well as trigger your flash from the camera position. The transmitter also runs on 2 AA batteries for power.
The receiver operates under the same guidelines as the transmitter with the ability to select from 16 channels. Instead of battery power, it draws its power from the USB connection it makes with the Pro-Flash unit. This all runs with a frequency of 433 MHz for general operation.
