With Police departments increased use of Laser for Speed traps it is highly recommended to add a Laser Stick to the front of your car in order to confuse the laser speed measuring devices so that they are unable to instantly get your speed. With laser, by the time your detector goes off they may already have your speed. The Speed Stick prevents that and with the warning from your detector you have time to slow down before a good speed reading can be obtained. A serious recommendation from Radar Rob
