Daily Telegraph on Snooper Indago

Chunky, pleasing to behold and uncluttered by buttons, it is a perfect miniature replica of a flat-screen TV - a 32-inch Sony accidentally put through several hot wash cycles.

The manufacturer claims the neat, stubby antenna is the most powerful GPS receiver in its field, and the Indago works out where it is almost instantly (tall buildings and trees don't appear to be major impediments).

Its digital maps are sprinkled with speed camera locations and other hazard information. Although marketed as a "plug and play" device, with no mandatory internet updates, you'll need to subscribe to a download service to keep your finger on the pulse of Gatso installations.

It costs a bit more than similar products, but then operation is a smidgen more intuitive, the screen less prone to reflected glare and the mapping a little more, well, map-like.
