Carrollton Township police frequently try to curb speeding in the community's subdivisions. Soon, they will have new technology to do so.

Members of the Township Board of Trustees on Wednesday approved the purchase of an UltraLyte 200 speed enforcement radar, a handheld device its manufacturer says will drastically improve the ability to catch speeders.

With the old technology, a fixed radar inside each car, officers could record only the speed of vehicles traveling in the opposite direction. A car driving or parked facing north could clock a car only driving south, and so on.

With the handheld unit, officers can park in hidden areas or even get out of their cars if they wish, said Police Chief Craig A. Oatten.

"This is a more versatile way to handle traffic enforcement," he said. "Several other agencies have it, and they are very happy with it."

Oatten said the radar uses a laser that identifies its target and then calculates the speed.

The device, which Centennial, Colo.-based Laser Technology Inc. manufactures, will cost the department $2,845. In-car radar units cost $3,500 to $5,000, Oatten said.

The radar is accurate to within 1 mph and has a maximum target range of 2,000 feet. The state is supplying and endorsing the device, Oatten said.
