What Are We Up Against?
The term EMF radiation doesn’t describe one single thing. It’s an umbrella term for different kinds of radiation we face on a daily basis.
Have a look.
Low-Frequency Magnetic Fields
Electrical currents in devices like power"Power" in a scientific context refers to the rate at which work is done or energy is transferred. In simpler terms, it's how fast something is using energy. For example,... More lines, household wiring, and large appliances such as refrigerators and washing machines create magnetic fields.
These fields are usually strongest close to the source and decrease rapidly as you move away.
Studies suggest that prolonged exposure to strong magnetic fieldsDefinition and Nature of Magnetic Fields Magnetic fields are a fundamental aspect of electromagnetic fields, produced by moving electric charges (electric currents). The strength of a magnetic field is measured... More can cause problems like sleep disturbances, chronic fatigue, and even increased stress levels in sensitive individuals.

Electric fields have a more limited range than magnetic fields (6-8 feet outside the electrical wires) but can still affect the immediate area around the source.
They’re often present in high concentrations in spaces with multiple electronic devices or complex wiring systems.
Radiofrequency (RF) Radiation
RF radiation is high-frequency radiation that comes from wireless devices such as Wi-Fi routers, cell phones, Bluetooth gadgets, and, increasingly, 5G"5G" refers to the fifth generation of wireless communication technology, a step up from the previous 4G, 3G, and 2G networks. It's designed to provide faster internet speeds, more reliable... More networks.
RF radiation is more energetic than low-frequency fields and is subject to ongoing scientific scrutiny.
Thousands of studies around the world have linked long-term RF exposure to problems like headaches, brain fog, anxiety, and even chronic diseases like cancer.
You can learn more about the health effects of EMF radiation on my “EMF Health Effects” page.
In urban environments or tech-heavy homes, RF radiation levels can be high due to the dense presence of Wi-Fi networks, cellular signals, and wireless devices.
This is where specialized RF meters, like the Safe and Sound Pro II, provide highly accurate readings and help users understand their exposure to RF in detail.
But today, we’re not focusing solely on RF radiation or the Safe and Sound Pro II.
We’re taking a comprehensive look at both the TriField TF2 and the Safe and Sound Pro II to see which one stands out as the better tool for your specific circumstances.
So, let’s dive into the comparison.
An In-Depth Look at the TriField TF2
The TriField TF2 is a versatile, multi-functional EMF meter designed to measure magnetic, electric, and RF fields.
This capability makes it a solid choice for users who want a single device to monitor multiple types of EMF sources.
Key Features of the TriField TF2
The TF2’s comprehensive EMF detection allows it to monitor all three main types of EMFs, giving it an edge over single-function meters.
Its frequency-weighted mode is particularly useful for health-conscious users, as it adjusts readings to show how EMFs interact with the human body.
Higher frequencies, for instance, create stronger currents in biological tissues, and the TF2’s frequency-weighting mode accounts for this, offering readings that correlate more closely with potential health impacts.
The TF2 also offers 3-axis magnetic fieldIn the context of electromagnetic fields (EMF), the term "field" refers to a region in space where electric and magnetic forces are exerted. An electromagnetic field is generated by electrically... More detection, which improves accuracy.
Unlike single-axis meters, which need to be held at a specific angle, the TF2 can be held in any orientation and still provide reliable readings.
This feature simplifies use and makes it suitable for less experienced users.
In terms of usability, the audio indicator is a standout feature, allowing users to follow sound cues to locate high-EMF sources without needing to look at the screen.
This is particularly helpful for identifying “hot spots” around appliances or wiring.
Pros and Cons of the TriField TF2
| Pros | Cons |
| Measures multiple EMF types (magnetic, electric, RF) | Limited RF range (up to 6 GHz) |
| Frequency-weighted mode simulates biological impact | RF sensitivity is moderate, not as high as Pro II |
| 3-axis magnetic detection for accuracy | Larger size, less compact than some other meters |
| Audio indicator helps locate sources quickly | No color-coded display for instant level assessment |
An In-Depth Look at the Safe and Sound Pro II
The Safe and Sound Pro II is designed specifically for RF detection, offering superior sensitivity and accuracy for high-frequency EMFs.
This focus makes it ideal for users primarily concerned with RF exposure from Wi-Fi, Bluetooth, and cell towers, especially those who live or work in RF-heavy environments.
Key Features of the Safe and Sound Pro II
The frequency"Frequency" in the context of electricity, Electromagnetic Fields (EMF), and wireless communication, can be thought of as the number of times something happens in a second. Specifically, it refers to... More range of the Safe and Sound Pro II spans from 200 MHz to 8 GHz, covering both low- and mid-band 5G frequencies, Wi-Fi, and other common RF sources.
This extensive range allows it to detect nearly all sources of RF radiation, making it one of the most comprehensive RF meters available.
One of its standout features is its high sensitivity, capable of detecting levels as low as 0.001 µW/m².
This precision makes it suitable for users who are electromagnetically sensitive, as they can identify even the lowest levels of RF and design low-exposure zones in their environment.
The OLED display on the Pro II is another valuable addition. This screen provides color-coded indicators that show RF levels in real time, from green (safe) to red (extreme), allowing users to instantly gauge exposure without needing to interpret numeric readings.
This feature is particularly useful for users who want to quickly assess exposure without extensive technical knowledge.
Finally, the Pro II’s sound signatures differentiate between RF sources by emitting unique sounds based on the type of radiation detected.
This function enables users to identify RF sources like Wi-Fi or cell towers without needing to analyze each reading individually.
Pros and Cons of the Safe and Sound Pro II
| Pros | Cons |
| Exceptional RF sensitivity (down to 0.001 µW/m²) | Limited to RF detection, lacks magnetic/electric measurement |
| Broad RF range (200 MHz – 8 GHz) | Shorter battery life than TF2 |
| Color-coded OLED display for easy reading | Higher price point |
| Sound signatures for source identification | Not suitable for low-frequency EMF detection |
