The Best Radio Frequency Detectors to Buy Right Now

It’s crucial to familiarise yourself with the types of signals you can encounter before purchasing a radio frequency detector. Although EMF and RF waves are often used interchangeably, they are typically separated by frequency intensity. EMFs are found in the electrical wire that carries AC currents, such as the wiring in your walls and the cords that power your appliances, at a lower level. Radio waves are employed by devices that transfer data, such as radio receivers, TV antennae, WiFi routers, and cell phones.

A handheld detector can detect both types of frequencies. Countersurveillance can make use of RF detectors. An RF detector can help locate surveillance devices such as recorders or cameras that have been hidden in a room. Although this may appear to be a far-fetched fear, there have been various privacy concerns reported in connection with private holiday rentals where hosts snoop on tenants.

Lower-level EMFs can be detected by some of the best RF detectors, which can be beneficial if you work in electrical engineering. An RF detector, for example, could assist you in identifying difficulties due to poor wiring.

How We Chose the Best Radio Frequency Detectors

Because there are many different types of signals that can be encountered, we chose detectors that can detect both RF and lower-level EMF signals. Our picks are compact enough to fit into a bag and are excellent for traveling to vacation homes or assisting a friend with a DIY project in their house.

1- TriField Electric Field Radio Frequency Meter

TriField Electric Field Radio Frequency Meter

This helpful instrument can assist in the detection of a variety of electromagnetic signals. You can track AC magnetic, AC electric, radio frequencies, and microwave frequencies using adjustable dials. The device has a handy designated knob that allows you to scan for the signals you’re looking for without becoming distracted by unnecessary background information. The digital display is simple to read and changes dynamically to assist you to locate hotspots. Instead of the rechargeable batteries used by the GQ, ERICKHILL, and other detectors on this list, this option uses alkaline batteries.

2- Poniie (RF) Digital Multi-Fields EMF Meter

Poniie (RF) Digital Multi-Fields EMF Meter

Poniie’s affordable option scans RF and EMF signals, making it a handy instrument for a wide range of applications. This option, like the Erickhill and GQ detectors, is powered by a rechargeable battery. It’s simple to receive a reading at a glance thanks to the huge illuminated display.



This EMF meter from Erickhill is a cheap choice worth considering if you’re specifically wanting to detect lower-level emissions. This detector does not scan for radio frequencies like the GQ and Trifield choices, but it does scan for electric and magnetic fields. This meter, like the GQ RF meter, is powered by a rechargeable battery.

4- KORKUAN RF Detector


This detector from Lonove includes various functions to identify concealed cameras, bugs, and other invasive devices if you’re concerned about personal privacy and security. It has an RF detector that detects signals from a number of sources. The probe makes it easy to locate the position of signals, and the unit’s light-up display indicates signal intensity. The infrared window is also intended to assist you in locating any hidden cameras.

5- Ebarsenc Anti Spy Detector

Ebarsenc Anti Spy Detector

The Ebarsenc Anti Spy Detector has a discrete design that makes it the greatest RF detector that appears like a pen. The small, compact gadget is powered by a lithium battery that may last up to seven days on standby or 25 hours of continuous operation. In a 10 square meter zone, the Ebarsenc can identify hidden cameras. The Ebarsenc includes a rotary signal sensitivity control and may be adjusted to vibrate mode. A flashlight is located on the bottom of the unit, which is shorter than a smartphone, for enhanced convenience.

6- GQ EMF-390 Multi-Field Electromagnetic Radiation 3-in-1 Reader

GQ EMF-390 Multi-Field Electromagnetic Radiation 3-in-1 Reader

The GQ features numerous sensitivity levels that make identifying and testing a range of radio waves, such as microwaves, power lines, smartphones, and more, a breeze. The GQ, which can detect a 5G network signal as well as RF up to 10GHz, can warn users if the waves surrounding them are producing an unsafe amount of power, and a built-in RF spectrum analyzer allows for real-time RF monitoring. The date and time, battery level, graphs, peak readings, primary readings, data kind, and suggestions for a suitable power source are all displayed on the GQ’s screen.

7- EMFields Acoustimeter

EMFields Acoustimeter

The EMFields Acoustimeter is well worth the investment for an EMF reader who is very sensitive to frequencies. The tiny handheld detector covers a range of 200 MHz to 8 GHz, making it one of the most versatile personal detectors available. The unit’s LCD screen, which delivers the most precise information, and its LED lights, which light up quickly to show consumers a wide variety of waves present, display the readings. The Acoustimeter can detect electromagnetic radiation from a variety of sources, including TV towers, microwaves, WiFi, and other similar devices. There’s also a speaker and a headphone jack, as well as a carrying case.
