Logitech Professional Presenter R800
$149, from authorised dealers from Nov 19

ORATORS who feel tied down to their PowerPoint setup can get untethered with this wireless presenter.

You can pace up to 30m away from your PC and still be able to work your slides. An LCD display shows you the reception-level signal in case you wander too far.

The same display also counts down the time you have preset for your talk - the 71g pointer discreetly warns you with silent, vibrating alerts.

Setup is easy: Detach the receiver from the presenter and plug it into a USB port of the PC.

No software installation is needed.

The R800 hides a secret weapon - a powerful green laser which is brilliant enough to be used in a bright room or on LCD and plasma displays.

Beats the dime-a-dozen red laser pointers.
