The Targus Laser Presentation Remote features a simplistic button layout, making it easy to give presentations. The Key Lock™ Technology locks non-essential buttons when not needed to help eliminate accidental button presses. The integrated laser pointer allows the presenter to highlight important content while the backlit buttons provide visibility in environments with low lighting. The latest RF 2.4GHz cordless technology works from up to 40ft away, providing flexibility while presenting in large conference rooms or classrooms. The mini USB receiver stores inside of the presenter so it's always ready to use. The device is immediately ready to use and comes stocked with one AAA battery.
