"A 15-pound survey device, Leica Geosystems' SmartStation, lets officers record measurements and reconstruct an accident scene in 20 to 30 minutes. Before the SmartStation, they used a 300-foot steel tape measure, a pencil and paper to create a diagram of the accident. It was time-consuming -- the process took approximately three hours -- and not very accurate."
