The ACM Countermeasures Kit 1960's, 1970's


A cut above the Hotdog Alcheapo Detective Agencies who had $49.95 "bug detectors", this model was a professional grade countermeasures kit developed by Ted Swift that would check phone lines, electrical wiring and sweep a room for RF signals. The kit sold for about $1895.00, a lot of money for it's time. This kit has been used by Ralph Thomas on major TSCM sweeps.

On the left is the ACM RF Detector. It had an adio verification mode with other plug-ons. On the right is the ACM main TSCM sweep box. It did it all! Become of the various setting and modes, it took some practice and time to learn how to use all it's features.
