Techknow: Smart tools - The Garmin eMap - What is it?

Last Updated: 31 Aug 2010

What is it?

It looks like a cross between a mobile phone and a Gameboy, but is actually a hand-held electronic map.

What does it do?

It stores digitised road and street maps in its memory and displays them on an LCD screen. The big difference between this gizmo and a conventional A to Z is that the eMap uses global positioning system (GPS) technology so that it always knows where you are and which way you are travelling - to within 10 metres. With one of these in your pocket, you won't leave the station and stride off in the wrong direction again.

What's the competition?

Regular pocket GPS units are popular with outdoor types, but provide only a latitude/ longitude position. In-car navigation devices have more features but are no good to pedestrians. Until the next generation of internet and GPS-enabled mobile phones comes along, the eMap is more or less unique.

When can I get it?

Available now at about pounds 350.
