Kensington Computer Products Group has released the US$79.99 Wireless Presenter Pro with Green Laser Pointer (http://us.kensington.com/html/13361.html). It provides an "ultra-bright" green laser, an extended 150 foot wireless range, four intuitive control buttons, a USB receiver that stores inside and a travel case.

According to Bill Rathbone, Kensington global product marketing manager, studies have proven that the human eye is naturally more sensitive to green than red light, thus making a green laser presenter brighter than a standard red laser. Green laser technology, which is as much as 10 times more visible than comparably powered red lasers, will also stand out more against today’s brighter projectors, plasma displays, LCDs or bright rooms, he adds. The Kensington Wireless Presenter Pro with Green Laser Pointer will work on virtually any screen or surface.

The Kensington Wireless Presenter Pro with Green Laser Pointer is a 2.4 GHz wireless device with an extended 150-foot range. It's Mac and PC compatible and works with Keynote and PowerPoint.
