Drivers beware! While this device is the smallest speed trap in the world, it certainly packs a mighty punch. Thanks to clever technology, it can pinpoint speeders on busy motorways, or even in bad weather. Called the SpeedLaserB, it fits snugly in the palm and is designed to be no harder to use than a pair of binoculars.
Developed in the US, the compact piece of kit can register speeds of up to 200mph and takes three-tenths of a second to calculate how fast a car is travelling. It uses laser technology to pinpoint specific vehicles on a busy road.
The speed is then flashed up on an LCD head-up display. Obstruction mode allows the lasers to function in heavy rain, fog and snow, or even through the windows of a patrol car.
