About Spy-Nexus

Who We Are and Who Buys Our Products

Spy-Nexus is an affiliate of Great Southern Technology Inc, a Georgia corporation, and our counter-surveillance equipment was designed by John Meyner. He started in this industry in 1966 and is a recognized authority in the counter-surveillance field.

The FBI sought his assistance when attempting to identify and analyze the actual bugging devices used in the Watergate break-in which eventually led to President Nixon's resignation.

Mr. Meyner was repeatedly invited by Mike Wallace to appear on the national program 60 Minutes to discuss bug detectors and the various eavesdropping equipment involved in the break-in.

For more than 40 years, Mr. Meyner has designed and sold electronic equipment to many of the largest companies and government agencies in the U.S. including the following:


  • Los Angeles Police Department
  • Chicago Police Department
  • Dallas Police Department
  • State Attorneys General
  • United Nations
  • NASA
  • US Department of Justice
  • US Naval Weapons Testing Lab
  • IBM
  • General Electric
  • Continental Airlines
  • Bell Telephone Laboratories
  • Opryland
  • Allied Chemical
  • Jet Propulsion Laboratories
  • Westinghouse Electric

When the New York City Transit Authority (the subway system) experienced a rash of armed holdups and a number of clerks were murdered, New York turned to one of Mr. Meyner's companies in New York for assistance.

The equipment that the Transit Authority possessed at the time would not operate properly in the heavily shielded underground subway system. He subsequently designed a transmitter-receiver combination which enabled the N.Y.P.D. to set up surveillance systems at a number of change booths. This resulted in the apprehension of the murderers and returned safety to the passengers and the clerks of the New York subway system.

Over the years, Mr. Meyner and his various companies, have been written up in numerous newspapers, magazines, and national publications including best-selling books and top-ranking websites such as:

  • Time Magazine
  • The New York Post
  • Gizmodo.com
  • The Electronic Invasion
  • The Covert Catalog
  • The Anarchist's Cookbook

In short, Mr. Meyner knows this business as very few others do!

If you have a need for efficient and reliable, yet moderately priced professional bug detection equipment, you may feel confident that you are doing business with an acknowledged expert in the field.

- J.M., Oxnard, California

I've used your MCD-22H Bug Detector to sweep my phones, my home and office, and even my car! I feel so much more secure knowing that my conversations are truly private.

- R.H., Montreal, Canada

Thanks for the fantastic instruction guide that came with your MCD-22H. I'm not very technical but I just followed the instructions step by step and quickly felt confident even with the advanced detection techniques.

- T.S., Louisville, Kentucky

I can't tell you how much I like your CSD. I've compared it to similar types of equipment, but none have the complete capabilities or are priced like it. On a recent job ...(several) different taps were being used...and using the CSD, I pointed them out to my client.

- M.J., Helena, Montana

We manufacture all our products including the MCD-22H and the CSD-21 (upgraded from the older model, the CSD-18). Both are the best selling counter-surveillance detectors in the U.S. They are both used by police agencies, private investigators, security firms and individuals in all 50 states.

We've just upgraded them for additional sensitivity and increased the detection operating frequencies of both detectors to levels unheard of in their price range.

Mr. Meyner has been in this industry for over 40 YEARS with manufacturing facilities in Georgia for the past 15 years.

There must be a good and sound reason why he has been so successful for such a long period of time. And, there certainly is.

It's because his equipment delivers every single thing he promises!
