Variable intensity, interconnectivity and master control of all make these the "top of the line" markers.
The new advanced stage marker will save you lots of time and trouble. Each unit comes with three interchangeable LEDs: red, green, and orange. Optional blue LEDs are also available. With only one unit, you can have any color you like--just change the LED!
They are individually dimmable or can be controlled by a master control when linked together by standard telephone line but you are responsible for building your own controller. If you're up to it, ask us for pinout instructions.
Each stage marker is powered by its own 9 volt battery. They are about the size of an old fashioned Motorola pager so you can see they aren't very big.
