Satellite-Synchronized Clock Display Kit

Just plug-in and go. This kit comes with a satellite-synchronized clock, a large digital clock display, and all accessories to work right out of the box with a quick-start instruction sheet. The clock supplies accurate time to synchronize up to 15 display clocks. The clock display has high-visibility LED digits that may be read up to 200 feet away. The clock and display are designed to work in harsh environments with a wide operating temperature, making them suitable for industrial applications.
