Description

If you’re looking for a reliable and professional-grade bug detector, the T-9 Bug Detector is the one for you. Trusted by security professionals for over 12 years, the T-9 is a proven favorite.

The T-9 is an RF (radio frequency) detector that can locate most wireless cameras and microphones. To ensure accurate detection, turn off your wireless router and phones before use. The T-9 can detect nearly all wireless bugs, providing you with peace of mind.

Using the T-9 is simple. It finds both analog and digital bugs, with lights that get brighter and vibrations that intensify as it gets closer to the bug. Its audio assist feature lets you hear what the bug hears, helping you pinpoint its exact location.

Hiring a private investigator for bug detection can be pretty expensive... with the T-9, you can do it yourself at a fraction of the cost. Our detailed instructions guide you through the process, and we’re always available via email for additional support.

How It Works

When someone uses the term ‘bug’, they’re usually talking about a covert device that sends a wireless signal. That device could be a hidden camera or microphone. The signal it sends usually goes anywhere from 50-500 feet, but it could go further.

The signal that’s being sent goes to a receiver. That receiver could be send to a tape recorder, or even a person camping inside a van like you see in movies. Yes, law enforcement actually does that! That signal can be detected with a bug detector.

So, you think you’re being bugged. Turn off all your electronics that emit signals, like wireless routers and cordless phones. Flip the power switch on the detector, and pay attention to the LEDs on the bug detector. If it senses a weak signal, a couple of LEDs might flicker.

The stronger the signal, the brighter the LEDs get. As you walk around the room, pay attention to those lights. If there really is a wireless bug, you’ll be able to pinpoint where it is.

Expert Advice

The T-9 has been produced for over 14 years, and it’s probably the most popular counter surveillance tool with private investigators that work with us.

The audio assist feature can be very helpful, and no other bug detector has that benefit. The next step up from this is more than twice the price, which makes the T-9 a great choice.

Where do you ship to?

We can ship to any address in the USA. This includes homes, apartments, businesses, and private mailboxes.

We can also deliver to PO and APO mailboxes, but cannot guarantee 2-day and overnight deliveries will get there on time as USPS doesn’t guarantee these services.

If you would like something shipped internationally, our clients outside the USA seem to like MyUS.com as a low-cost method of having packages forwarded.

The shipping label doesn’t say SpyGuy, of course! It says ‘Fulfillment Center’ and has the return address of the fulfillment center. The package contents aren’t listed on the packaging.

If you do an online search for the fulfillment center’s address, it doesn't return anything related to SpyGuy.


I want this sent somewhere else, is that okay?

We understand some clients don’t want this sent to their home or business, and that’s fine. Just give us the full shipping address you want this sent.

Make sure you also add the billing address, which is tied to your credit card or other payment method, otherwise your payment might get refused.

FAQ

Here are some of the most frequently asked questions:

How do I know if the detector is working?

When the T-9 is turned on, it scans for radio frequencies. As it gets closer to a bug, the lights will get brighter, and it will start to vibrate.

Can the T-9 detect hidden cameras and microphones?

Yes, the T-9 can find most wireless cameras and microphones by detecting their radio frequencies. If it's using a rarer technology outside the frequency range, it won't be detected.

Do I need to turn off my Wi-Fi and phone while using the T-9?

Yes, to avoid interference and ensure accurate detection, it's best to turn off your wireless router and phones.

Is the T-9 easy to use if I'm not tech-savvy?

Absolutely. The T-9 is designed to be user-friendly, with clear instructions included. If you need help, you can always email us for support.

    Found the Secret Surveillance

    It is so discreet, just raised the antenna and put it on vibrate mode in the deep pocket of my vest. Whenever it vibrated I located suspicious items and simply shifted them and watched the peepers running around to try to figure out what was wrong with their secret surveillance equipment. LOL, then they kept walking near us with blue tooth phone playing music to try find out if we had a detection device but it was on vibrate mode so it didn’t chirp. More fun than a barrel of monkeys, thanks SpyGuys!
