Our Mission

At CSECO, our mission is to eliminate the distribution of illegal drugs that continue to ravage our communities, as well as reduce the risk of loss of life from the transport of dirty bombs, explosives and illegal weapons. We keep this mission, these goals, in mind with each contraband detector we design and manufacture. Unlike some of our competitors, and because we take this mission so seriously, we sell exclusively to qualified federal, state, local and international law enforcement agencies only.
