Wireless presenter features a brilliant green laser that's eight times more visible than standard lasers to make your point even in the brightest auditoriums. With a 100' range and intuitive presentation controls that are compatible with PowerPoint and Keynote, feel free to move around the room to engage your audience for greater impact. Backlit LCD allows you to quickly take a glance at the timer and signal strength to keep your presentation on track. Vibration alerts can be set at predetermined times for convenient reminders, such as when you only have one minute left in your presentation. Plus, its easy-to-use design does not require you to install any software for immediate use. Presenter is Mac and PC compatible.
