Several new models have hit the market since our extensive test of detector (evo 15), so we've tried some of the best-sellers.

To cut through the jargon, k and ka bands are the most commonly used in the UK.
Both GATSO and hand-held radar work on these bands. Many detectors are based on US models, which means they also detect X band.

This used to be the source of majority of false readings. Fortunately, the latest units allow X band detection to be disabled. Mini GATSO cameras work on Ku band, but their use is not widespread.

Our verdict

Each detector claims comprehensive cover against police methods of monitoring speed. We were unable to carry out a controlled test, but the various units were tried out over a period of several weeks. The Bel units and Valentine One gave ample warning on approach to a GATSO camera. The directional indicator on the Valentine was also a useful feature. The Snooper was less sensitive, but gave just enough warning to react. False alarms were not a problem on dual-carriageways or motorways, but could become tiresome in town.

The Bel Euro 330 and 550 are developments of the 980 and 990 models which cleaned up in our previous test (issue 015). We've seen nothing to change our recommendation this time around. Both are designed specifically for use in the UK (and Europe in the case of the 550) and work extremely well. The Euro 550 performed marginally better with GATSO, and its settings can be changed country by country. These features warrant the extra money over the 330 , but both are a good buy.
The Valentine One is an impressive looking unit with some good features. However, its US roots show through with the lack of Ku band detection, and a display angled towards the left of the cabin. The price also counts against it.
