Logitech today introduced MouseMan Dual Optical, a new USB mouse that features two optical sensors for higher accuracy and precision on a broader range of surfaces. Each sensor provides a resolution of 800 dpi–twice that of previous sensors–and is positioned at a 45-degree angle from the opposite sensor. According to Logitech, the mouse monitors both locations from different angles to extract the best possible reading of mouse movements. Mirroring many of the same design features as the Cordless MouseMan Optical, MouseMan Dual Optical features a contoured design for the right hand, four programmable buttons, scroll wheel, and support for Macs running Mac OS 8.6 or later. The mouse will be available this month for $49.95.
