It is almost impossible to trust any new place you enter, and not expect to find such predatory items. Especially when they come in sizes small enough to fool the naked eye. From screws, clocks, tissue boxes, and even toilet paper holders have been reported to carry camera lenses or microphones hidden with delicate intricacy.
Therefore, it is best to carry an RF Signal detector whenever you travel as these will aid in protecting you when you are the most vulnerable.
To make sure of your safety, a credible RF detector is needed. For this, you must inspect certain factors:
A good quality RF detector must pick up a wide range of frequencies. And to be able to make sure one does, it is better to check where certain devices rank in the RF spectrum. You have different frequency band names like:
- High Frequency – 3 to 30 MHz (Software Broadcasts)
- Very High Frequencies – 30 to 300 MHz (FM Radio, TV Broadcasts, Mobile communication)
- Ultra-High Frequencies – 300 to 3000 MHz (TV, WIFI routers, Wireless LAN, Cordless phones, Bluetooth, 2-way Radios and many more)
- Super High Frequencies – 3 to 30 GHz (Wireless LAN, WIFI Routers, cable, Satellite TV broadcasting and some cordless phones)
Many radio devices have multiple ranges of frequencies, so if your RF detector has a wide range, you should be on the safe side. Do know that a camera not emitting signals in real-time will not emit a signal. For that, you would need an RF detector that picks up camera signals too.
Sensitivity and Filtration
It is all about sensitivity when it comes to RF signal detectors. The best RF Signal detector will be able to pick the faintest signals being emitted in an area. Cheaper RF detectors are only good at telling the type of emissions in a certain space. But if you invest in a high-priced device, specificity regarding such signals is also exhibited in the readers.
It all depends on the specificity of the need for a user and their privacy. Filtration of signals amongst RF detectors is also key in getting to know hidden bugs. This is because an RF signal detector must be able to pick hidden pieces instead of the obvious day-to-day use items. High-priced detectors come of sue here as they excel at the sensitivity and picking out ambient signals.
Long battery life comes of great help, especially when you are travelling to new places. You must have the device up and running when checking into hotels or even going into shared toilets or changing rooms. A device with more than 12 hours of battery life is ideal in such situations. This way, you won’t have to wait for the device to come back to life when certain urgent situations arise.
That’s just about it. Now, let’s take a look at the best RF signal detectors market has to offer.
1. Electric Field, Radio Frequency (RF) Field, Magnetic Field, Strength Meter by TriField
The first on our list of Best RF signal detectors is the 3-field strength meter by TriField. This detector will be your best bud, especially when you are a rookie and don’t know much about the complexities of certain fields and waves.
The TriField Detector has a sensor capable of detecting AC Magnetic (3 axes), AC Electric (1 axis), and RF/Microwave (1 axis) fields. The device is backed by a 9V alkaline battery that comes with its indicator giving you a working time of >20 Hrs (backlight off) and >12HRs (backlight on).
Measuring 1.5 x 2.8 x 5.2 inches, the RF signal detector has a wide analog display that is very easy to use. You just need to twist the knob to measure any field. The large LCD will show clear readings to which you can adjust the backlight accordingly. The best part? It can quickly catch fast pulses of both standard AC readings and weighted High frequencies as well.
However, this device does not come cheap. If you want a more affordable device, take a look at the other RF detectors on our list.

2. EMF Meter, Advanced GQ EMF- 390 Multi-Field Electromagnetic Radiation 3-in-1 Meter
Another worthy opponent built with reputable signal catching meters. The device is packed with high sensitivity multiple sensors for easy and quick signal pick-up. These can pick signals from Power lines, Smart Meters, Cell Phone Microwaves, and even 5G Network signals and RF up to 10 GHz.
The system also has a built-in RF spectrum analyzer along with GQ RF Browser for real-time monitoring. That’s not all! With its 3axis Electromagnetic, electrics fields, and radiofrequency up to 10GHz, no bug shall go un-discovered. It can even recognize the source of RF emission.
The backlit wide LCDs all required readings and makes them easy to understand. It can easily pick up EMF, EF, and RF and make you vigilant of the current situation instantaneously. Additionally, it measures 5.5 x 3 x 1 inches, which is quite compact and portable. The device is supported with Lithium-ion batteries and can be charged with a USB cable.
The only limitation of this model is its limited capacity to pick up intermittent signals.

3. Anti-Spy RF Detector Wireless Bug Detector by JMDHKK
Next in line, we have the anti-spy RF signal detector. It can detect 1.2G/2.4G/5.8G hidden wireless camera and eavesdropping bugs and locaters with mobile 2G/3G/4G cards with a range of 1MHz- 8MHz.
As for its sensitivity, signal detection is unmatched with strong anti-interference with the latest chipset technology. The 3 in 1 detector’s wide range detection can track any type of GPS tracking or wiretapping. With its lightweight, portable structure, it is super easy to go into stealth mode anytime, anywhere. The device starts giving off a beeping alarm and indicator lights, as it gets closer to the bug.
Simply adjust the sensitivity from high to low, to specify the pinpoint location of the bug. Weighing only 150g and measuring 117 x 56 x 20mm in size along with a 3.7V 100mA polymer lithium battery, this device is worth your serious consideration.
The operating mechanism is a bit hard to figure out. Thankfully, the instructions manual comes in very handy. It mentions everything from setting up to troubleshooting and making the most out of your purchase.

4. Sherry Anti-Spy Detector and Camera Finder RF Signal Detector
A bug detector perfect for any situation or place. Sherry had to be on our list of best Rf signal detectors. It has a wide range of 1MHz to 8000 MHz, dynamic range if >73DB, and a critical sensitivity of < 0.03mv, along with a detection range of 40 ft. You can adjust the sensitivity and detection range if needed. What’s more, it can easily detect a wide range of signals very easily.
The advanced chips in this device keep you safe from all sorts of GPS trackers, Magnetic detections, or chances of data theft. The numbers and light indicators make this RF signal detector capable of keeping your privacy safe from sneak shots, tracking, blocking, or unwanted location sharing.
Built with a 1200mAH Li-battery, it gives a working time of 8-10 hours and measures 6.2 x 4 x 2 inches in dimensions. Which is pretty compact, don’t you think?
Our only disappointment is its Analog display. A little more detail would have helped users better utilize this amazing hardware.

5. HOHOPROV RF Signal Detector
Lastly, we have the HOHOPROV Rf signal detector, capable of picking up nasty little bugs through its 5 detection modes. These include laser detection, vibration (mute) detection, beep detection, LED display detection, and finally, the headset mode. So this is a very versatile device.
Its potentiometer has high sensitivity and can also be tweaked to adjust the threshold to widen your detection range. Moreover, It is capable of picking up signals of spy devices like hidden cameras, audio bugs, or GPS tracking quickly and efficiently. To fish out cameras with or without real-time transmission, this device’s chipset offers laser scanning and an indicator light signals to identify the source of emission.
This RF detector is rechargeable and measures 3.6 x 1.8 x 0.7 inches and has a working time of a total of 5 to 6 hours. The system will set the indicators in action when switched on near a bug and guide you.
Nevertheless, it falls short in one aspect of pinpoint bug indication. Instead of 360 degrees detection, you have to point at or on stuff for more accurate detection. But it is not a big deal. This affordable device can be a perfect first RF Signal detector for anyone venturing into the anti-surveillance gadget marketplace.
