All-In-One GPS, Bug, Phone Tap and Spy-Cam Detector

Do you suspect that you are the subject of illicit surveillance? Do you fear that you and your vehicle are being tracked, that your private phone conversations are being monitored or recorded, or that the privacy of your vehicle, home or office has been violated? If you require total and completely dependable protection against ALL types of GPS trackers, against physical and spyware-based cellphone and landline taps, or against RF room “bugs” and transmitting spy-cams, then the MCD-22H All-In-One Combination Detector will prove the ideal solution.

Could Someone Be "Listening In" or Tracking You?

Don't for a minute believe that an eavesdropper requires any type of large, complicated transmitting device (many are smaller than 1 inch square) ... or that GPS trackers are only used by secret government agencies ... or that listening devices cost thousands of dollars!

As you read this, many "police-grade" telephone taps, spyware apps, and GPS tracking devices are presently being offered to the general public by a number of firms for incredibly low prices.

And remember, if your cell phone has been hacked or otherwise compromised, it may ALREADY be acting as a GPS Tracker and proximity bug! To rest easy, you need a Combination Detector to quickly sweep your vehicles, your phones, and your home/office. Only the MCD-22H can give you this three-fold protection!

Countless individuals and businesses are being enormously damaged by having their vehicle movements monitored and their private conversations overheard, monitored and recorded! Text messages, contact details, personal videos and confidential photos also regularly intercepted. And, almost without exception and AFTER the fact, the victim makes a statement along the lines of...

"But I Never Thought It Would Happen To Me!"

If you fear that your car may conceal a GPS tracker, if you suspect that your home or office may be bugged, or if you've noticed strange noises on your landline or strange behaviors by your cell phone, an efficient, combination GPS tracker detector/RF bug detector/phone tap detector is exactly what you need to provide full protection against all the variations of the latest techniques now employed by today's eavesdroppers.

In response to the overwhelming demand from businesses and individuals for an economical, yet completely dependable combination GPS, phone and bug detector, our engineers have recently developed the MCD-22H All-In-One GPS & Bug Detector.

The MCD-22H's unique and proprietary detection circuitry will detect and locate all the major categories of surveillance devices -- whether targeting your vehicle, your phones, or your home and office -- including all of the following:


  • GPS Tracking Devices
  • Landline Bugs and Wiretaps
  • Cell Phone Spyware
  • "Series" Telephone Transmitters
  • "Parallel" Telephone Transmitters
  • Room Bugs in Home/Office
  • RF Signal, Microwave and Laser Bugs
  • Spy-Cams and Transmitting Video Cameras
  • Computer and Fax Eavesdropping Devices
  • Body Wires
  • The "Infinity" Device

A true engineering breakthrough in bug detection, the extremely versatile MCD-22H combines a wide spectrum miniature GPS/RF bug detector and an ultra-sophisticated telephone tap detector in one compact 5" x 3" x 1" package, only slightly larger than a deck of playing cards!

Not "Just Another" Transmitter Detector

The MCD-22H is not a simple transmitting bug detector like those commonly offered by most security dealers. Aside from a few cheap "toys" that promise, but never truly deliver the higher frequencies, virtually all the other "detectors" presently offered on the Internet have a maximum effective top frequency detection range of about 3 GHz.

Today's eavesdroppers are not fools. They've seen this and have now raised the transmitting frequency of their bugs and telephone taps to above 3 GHz. This very effectively evades detection and allows them to continue to Eavesdrop on unsuspecting individuals that have been deceived into thinking that they were protected.

However, the MCD-22H's very broad detection range of 1 MHz to 9 GHz also protects against analog, digital, wireless and spread-spectrum ultra-high frequency transmitters.

The MCD-22H Also Detects The Infinity Device

And, not only does the MCD-22H quickly and easily detect the very latest transmitters, it also detects one of the most popular devices used by today's eavesdroppers known as the INFINITY device. Beware the Infinity Device!

With this space age eavesdropping device (also known variously as the Hook-Switch Bypass, Third Wire Tap, and Harmonica Bug) Eavesdroppers can literally monitor your confidential conversations With your telephone still "On The Hook!"

Everyone is aware of the widespread eavesdropping presently used to monitor telephone conversations and very few individuals now speak freely on the telephone.

You know it.... We know it.... The government knows it.... AND, THE EAVESDROPPER KNOWS IT!

He is completely aware of the fact that he will learn very little "useful" information by monitoring your telephone conversations. So now, over 95% of the time he doesn't even try!


He knows that while you won't speak freely on the telephone anymore, whenever your telephone is "down on the hook", your guard is also down. You'll speak confidentially to your wife . . . your business partner . . . your attorney . . . and usually give little, if any, thought to eavesdropping.

THAT is when you are most vulnerable. THAT is exactly when today's eavesdropper now strikes!

Very few eavesdroppers plant a transmitter and patiently sit 300 - 1,000 ft away from the subject and remotely monitor a receiver. That is far too costly, time consuming and just plain uncomfortable.

He would much rather monitor your premises whenever and from wherever he chooses!

And, that is precisely what the many variations of the INFINITY Device allows him to do.

He simply calls your telephone number and using a variety of electronic methods, prevents your telephone from ringing and then turns your telephone into a Super-Sensitive Listening Device.

He can now monitor all the conversations and even the slightest whispers in the room where the telephone (still on the hook) now innocently sits.


Hear What The Bugger Hears!

And, not only will the MCD-22H detect a concealed INFINITY DEVICE, the super-sensitive headphones included will also allow you to actually "LISTEN-IN" to everything that the eavesdropper is monitoring! With the MCD-22H, you can "tap" into your own phone line.
