The Activpen is Promethean's unique battery-free, wireless mouse-pen. It writes like a pen and acts like a mouse. The Activpen can activate mouse rollovers (hovers), right-click, drag and drop, highlight, open tools and applications, switch between pages and activate sounds and images. The mouse functionality allows you to 'double-click' for additional helpful tools with onscreen guidance. The Activpen is so accurate and precise, you can measure and mark on the Activboard to the millimeter or degree. Compatible with all AP10 ActivPanels.
