New outdoor audio and indoor visual

With its upgraded Windows 7 compatibility, the USB Digital microscope can connect to any classroom computer, and accommodate large group lessons when wired to a projector.

The new paging horn helps to ensure all messages are heard throughout the school year - wind, rain or shine, and can be easily mounted on the exterior of any school building.
