How common is the use of laser for speed monitoring?

Less than 1,000 laser guns are in service in 45 states at present. Most are used by city police on urban multi-lane roadways although some state highway patrols - Illinois and Ohio to name two - have dozens of units spread throughout the state. The use of laser guns for speed monitoring is expected to increase, but will remain limited due to their high cost-four times that of a moving radar-and limited attractiveness to agencies that favor the convenience, offered by conventional moving radar. Currently, laser guns account for less than 5% of the total number of speed monitoring guns (radar and laser) sold in the U.S. annually; during the next five years, this figure is expected to remain under 8%. Laser guns will likely be in service in every state within a few years.
