Gigahertz Solutions RF meters
Recently I have decided to add some of Gigahertz Solution RF meters since they have become very poplar in USA, Canada and EU. These meters are very accurate, very sensitive, very fast and very “German”(made in Germany). Their operation is not so simple as you need to use switches, Attenuators, external antennas and etz, but they allow a lot of flexibility in the measurement. To this day I have not used them my self but you can experience the operation of the meter from the video above.
Sampling rate is too slow – meter could not identify fast changing signals (WIFI, DECT).
I hope that in the future TENMARS will improve this very basic feature so the measurement will be based on at least 1000 samples and will show MAX value.
DT-1130 Electromagnetic radiation detector
As in other cheap devices, it reacts to the radiation only when being very close to the source. However it can still be used to scan a wall or a room (you need to be very close to the source, and even if you are it seems that the measurement is not accurate).
The manual say it can go up to 3500MHz, well I could not see how it can. I put it next to a working DECT phone, it did show a high level of Electric field, but the same level was seen when the DECT phone was out of the power socket( I am not sure what it measured in this test). So I am not sure, but is was not as responsive as I would expect it to be. In addition the manual say it’s Efields sensitivity is as low as 1V/m. This could be fine for ELF but not sensitive enough for RF.
In the pictures above, 0(none) then mid(10V/m) then high(344V/m) readouts of electric field just few cm. a way from the source.
In the pictures above, Left picture, no ELF magnetic field is detected from a audio amplifier. In the middle positioned picture, 3.21uT magnetic field just cm from where the meter was in the left picture. In the right picture the UHSshows a level of 10mG (1uT) farther away from the amplifier.
I think it may be usable only as a cheap ELF Electric and magnetic fields detector, if you can’t efford a more accurate reliable meter.
When in peak mode, the display averages all peaks within ½ of a second. The average peak is displayed on the display.
In RMS mode it displays the root mean square (RMS) average of all signals during that ½ second period. This reading is much lower than Peak mode when measuring a digital signal.
Easily detects cell phone towers, cordless phones even microwave oven leaks. Instructions in German and English. The sounds from this meter help distinguish different sources of RF.
The antenna is detachable to avoid damage during storage or when transporting so its a good idea to keep the original packing box and use it for protecting the antenna. by Chris Young P.E.

Carry pouch supplied
All EMFields own instruments are shipped in a carry pouch, with batteries pre-installed for your convenience. We don’t ship them in additional packaging for environmental reasons.
Do I need to be technical? The equipment we stock is easy to use, even with no technical background. Where international research has found adverse health effects at specific EMF levels, these are shown clearly in the instruction leaflets.
The RadAware RDis our Personal RF/microwave exposure alarm. Although there are now many meters and monitors that measure RF, there are virtually no sensitive personal RF/microwave exposure alarms.
The RadAware is designed to be left switched on, monitoring your personal exposure, and alerting you if it rises above your chosen level. It can be left on your desk, but it is also small enough to be carried in a pocket or bag. It is thousands of times more sensitive and detects more than twice the frequency range of other RF alarms we have seen. We designed the RadAware using our 2years experience of EMF/RF measurements and research.
What you need to measure
This represents the most important issue to resolve if you want to have the best experience. If you want to measure beyond just electromagnetic fields and you are also interested in microwave or radiation detections, it’s worth checking out the products that offer such abilities.
To help you even further, in the following section, the best EMF meters on the market are presented after lots of hours of research. There’s enough variation in terms of features and costs to please nearly everyone, so if you need a reliable and high-quality detector, your searches have come to an end.
An essential tool for any ghost hunter is a capable EMF detector and this one from Alternative Tech International allows you to detect any paranormal disturbances. It features a good audio and light indicator to enable you to go out in the dark and to keep monitoring even from far away. Even though it’s an inexpensive unit, it has solid features for the cost and is very easy to use.
Using this device is a breeze. The first thing that you need to do is to turn it on by pressing the large button found on the front of the unit. Then it’s simply a matter of interpreting the readings. If you go ghost hunting, you need to look for certain patterns like beeps, lights, and needle moves that are random and harder to predict. Constant readings are usually indicating power lines but those that come and go and change without apparent reason can suggest paranormal energy.
Each EMF meter is individually calibrated so the accuracy is quite decent. If the unit indicates a strange fluctuation and you’re quick enough, you can even take a photo and capture a picture of a ghost though that is quite difficult to do. The response time of this detector is on par with more expensive models and a great advantage of it is the ability to operate in silent mode so that it doesn’t distract other investigators and it also doesn’t interfere with Electronic Voice Phenomenon recordings.
Useful for more than hunting ghosts, The Ghost Meter EMF Sensor is a reasonably sensitive piece of equipment and can provide lots of uses and quite a lot of fun if you’re into detecting paranormal activity. It’s also a very affordable item to get for a kid or a teenager who is intrigued by the possible existence of ghosts. It doesn’t overwhelm the user with too many complicated gimmicks and it just simply does well what it’s supposed to.
KII KEMF Meter Deluxe Black Edition
This model stands out due to its lightweight and compact design. Despite the small size, it’s actually very durable and feels sturdy in your hands. The design of this detector has been enhanced for better paranormal research. It has been tweaked to be more reliable in the field and deliver more promising results. It’s simple to use, to monitor, and, perhaps more importantly, it’s a very quiet device.
It can sample EMF levels at reasonably fast speeds. You can see the results clearly when the device’s lights light up all of a sudden. To register the changes in EMF levels more clearly, the manufacturer added colorful lights and the activity is easier to see at night or from far away.
Perhaps the most important aspect of this meter is its efficiency. It’s capable of detecting paranormal activity and you can see its superiority compared to other detectors in various videos of ghost hunters. It covers a wide range of frequencies, from 30 to 20,000 Hz and this means that this is a reliable instrument for capturing high EMF levels in your home and not just for going ghost hunting.
Considering everything that’s been said about the KKII EMF Meter Black, it’s getting pretty clear that this represents a great buy on the market for EMF detectors. It’s easy to use and delivers the performance to accomplish its purpose effortlessly. The fact that it’s made in the USA provides an extra peace of mind knowing you’re getting a truly reliable and genuine product.
Cornet ED78S EMF RF Meter ElectroMagnetic Detector
Cornet is a very trusted brand in the industry and the ED78S is perhaps their best EMF detector. It offers reliable paranormal detection features in a compact package and also allows you to steer clear of the dangerous levels of microwave radiation. The price is not the lowest you will find on this list but if you want to obtain better value in the long run, this unit seems promising.
This meter is capable of handling the measurement of two types of EMFs. It detects radio frequency radiation, from items such as cell phone towers, WiFi routers, smartphones, and many others. It also measures magnetic fields like electrical powerlines, electrical substation EMFs, and the wiring from your house.
The sensitivity of this device is on par with what you’d expect at this price. It has two magnetic field settings and it measures from 0.mG to mG on the lowest setting and it has a resolution of 0.mG. The previous model had a 0.mG resolution so there have been some improvements in sensitivity. For RF readings it can capture up to GHz compared to just GHz of the previous model.
With the help of a reliable EMF meter, you can gain some useful insights into the types of radiation you’re exposed to in your own house regarding all the electronic equipment around. For a non-professional grade EMF detector, the Cornet ED78S does a solid job as it’s an excellent measurement tool for a decent price. The range and sensitivity are on point and you can definitely make smarter decisions about how you use electronic equipment.
KII K-II EMF Meter for Ghost Hunting
The older model from KII is still relevant in the world of EMF detectors as it packs a solid punch in terms of features per price. Simple to use and equipped with a multi-segment LED display that provides good visibility, this model is a great choice, especially when considering the accuracy of 5% at 50-60 Hz.
Durability is one of the strengths of this device as it has been outfitted with a durable plastic case that resists rain and accidental droppings on hard surfaces. It feels very rugged to the touch and it’s clear that it’s not easy to break. Paired with the solid battery life, this looks like a very reliable model. It comes with a 9V battery installed and it can last for approximately one year.
Reading EMF measurements in the dark is simple with the help of different colors that indicate the strength of the electromagnetic fields. When the lights suddenly flash you can be sure that some paranormal spikes have been detected. Compared to digital readings or needles from other meters, this system seems to work better. The readings can be viewed from far away if you intend to leave it in a room and watch it react to paranormal activity.
As it measures a wide range of EMFs, from 30 Hz to 20,000 Hz, this is a pretty sensitive unit and the detection process goes very quickly as the device is highly responsive. It’s important to note that the meter is noiseless which can be appreciated during haunted investigations.
If you need a reliable EMF meter for ghost hunting or for measuring electromagnetic fields created by various house items, this one can be an ideal option. The KII EMF detector generally works as intended though it has some issues with moving objects so perhaps it’s not ideal for ghost hunting and it’s more recommended for testing appliances.
LATNEX MG-300 LF magnetic Field Meter
Getting a capable EMF detector can be a worthy investment if you are doing regular EMF home inspections and it’s essential to get one that’s sensitive enough because various smaller electronics generate electromagnetic fields that are harder to detect. A good solution lies in the Latnex Mg-300, a meter used to measure EMF of extremely low frequency from 30 to 300 Hz.
This unit can measure electromagnetic fields with good accuracy and one of the best aspects of it is how easy it is to operate. When you buy a new home it’s a good idea to check the EMF levels so that you can understand what kind of radiation is found both inside the house and outside in the surrounding area.
Some of the most common sources of EMF radiation that can be detected with the help of this little gadget are power lines, electrical transmission equipment, and various household appliances. Long-term exposure to this radiation can be unhealthy so having a detector is crucial for future homeowners and real-estate agents who want to verify the EMF levels.
This device is lightweight and the manufacturer includes a handy carrying case and a protective boot to prolonge the life of the unit. The customer service from Latnex is really good as you can reach them easily for any questions or concerns about the meter or EMF radiation. This can be a must-have device to have you’re interested in moving to a new house or apartment as it allows you to make an informed decision and steer clear of hot spots of electrical fields.
Accurate and easy to use, the Latnex MG-300 is a great EMF detector and the price is quite fair too for what it offers. It’s recommended for anyone looking to have a handy tool around the house and it can even be useful if you ever intend to discover paranormal phenomena. It does have some reliability issues occasionally but after you learn how to use it correctly, it can provide accurate results.
Tools of the trade
When paranormal investigators aren’t trying to listen for the exact causes of cold chills and creepy feelings, they tap into technology to capture visual evidence as well.
In order to photograph spirits, ghost hunters turn to infrared and ultraviolet light. “‘Ghosts’ may only be visible in those wavelengths, which most humans cannot see but unfiltered digital sensors and some photographic films are able to record,” explains New England Investigator Anthony Duda.
Duda, who has been investigating the paranormal for more than 2years, is all about getting to the bottom of paranormal activity for his clients. In his line of work, he uses both still cameras and video camcorders.
Tune in to any of the ghost hunting programs on television and you’ll see investigators using simple recording equipment, too. You may even be inspired to whip out your digital camera the next time you’re walking through an old building. However, you might need to splurge a little if you’re as serious as the professionals. “The basic and affordable components of a ghost hunter’s toolbox in order of use and importance are the digital camera, audio recorder, EMF detector, and remote temperature sensor,” says Tom Elliott of Boston Paranormal Investigators.
The evolution of the hunt
As investigators work hard to figure out the paranormal, they have a mountain of technology to confront as well. Luckily, the five basic human senses are affordable resources they can use along the way.
Notice the sun emits light in many wavelengths that most don’t consider “Light”, they are not things we usually think of as light. That’s right, radio waves, x-rays and infrared are all “light” and come from the sun.
It’s important to use a light with a wavelength that actually has a biological impact on the issue you are trying to solve. We want the right type of photons hitting our body. Some lights actually use a white or blue wavelength of light and add a red filter. In other words, the LED driver is based on blue light and it only looks red because there is a red filter over the light. We want pure wavelengths of light, not just a red filter that might not give off enough red light in the wavelength we want. Other lights do use a true red wavelength but use one that has not yet been shown to be biologically helpful.
This chart pulled from the Joovv site shows that one of the receptors of light energy in our body, Cytochrome C Oxidase, absorbs many more photons at certain wavelengths.
I was able to spend an hour talking with Dr. Michael Hamblin from Harvard, one of the foremost researchers on photobiomodulation and we discussed wavelengths of light.
The most beneficial of these peaks are in the range of 660-670 nm and 830-850 nm. These wavelengths have been proven to produce substantial improvements in cellular function with a wide range of resulting benefits including improved skin health, enhanced muscle recovery, reduced joint pain, increased testosterone, and even weight loss! Alternatively, other wavelengths such as 700 nm or 720 nm have almost no biological effects. So, it’s critical to choose a device that delivers optimal wavelengths of light.
So, it’s critical to choose a device that delivers optimal wavelengths of light.
It has also been shown that Red light can penetrate 15mm into the body at 694nm wavelength.
I asked Dr. Hamblin if it was possible that synergies between multiple wavelengths would increase the benefit of a healing light device over one without such synergies.
Synergies between multiple wavelengths have not been well studied. However, Dr. Hamblin agreed that a combination of NIR and Red light worked well together and it’s possible there could be synergies between wavelengths but this isn’t something he has studied.
Dose matters. A lot.
Dr Hamblin recommends everyone, especially practitioners, but also those using photobiomodulation devices purchase a light intensity meter. Without this tool, you would have no way of knowing the total energy and intensity of the device, nor how far away to keep it from your body.
Mercola and Dr. Wunsch indicate that an intensity of 10-20 mW/cmis ideal, while Joovv and some research studies argue 50-100 mW/cmare better. I believe both ranges work. Remember that more is not better.
Dr. Hamblin talks about the biphasic dose-response curve. Too much light has a negative consequence and too little may do nothing.
A Biphasic Dose Response means that if you use too little you won’t get an effect and if you use too much you will get a negative effect. You need just the right amount. Using too much, too high an intensity, too long of a time under the light can be worse than no light at all.
It is not understood why the negative effect from PBM happens, but it could be due to too much ROS (reactive oxygen species) being created in the cell.
The red light you buy should list the intensity it uses. This is the only way to know how long to use it. It’s also helpful for the manufacturer to suggest how long to use the device for certain conditions. If you don’t know the intensity, or the manufacturer doesn’t list it, get an intensity meter and measure it. You want to ensure you don’t get too much light and harm yourself.
LED lights flicker because with alternating current the LEDs (light diodes) are turning on an shutting off many times a second as the current changes directions.
I took a slow-motion video of my Christmas tree lights vs the Joovv and Redjuvenator to find out. Often using slow motion on a camera, we are able to show the flicker effect.
Dr. Hamblin mentioned that pulsing of LED lights studied in the lab showed more benefit than constant photon flow and also said that flicker should not be an issue in PBM. Admittedly, he did not know much about flicker. But his belief is that pulsing light is more effective and therefore flicker in a light panel may possibly be a good thing. Remeber, it’s not good for working or general lighting to have flicker, but for short time use as light therapy, it might be worthwhile. None of the lights I tested appeared to have flicker.
If you have to supplement, you want to supplement with some of the important the missing components of indoor lighting. Red, infrared, UVA and UVB are missing in indoor light and can be supplemented.
Before using or buying a device, ask yourself what benefit you are looking for.
Chronic health concerns vs vanity concerns like wrinkles, age spots and collagen may require different criteria in a device.
Do you want to reduce aging, wrinkles, increase collagen? Light in the 630-660nm wavelength stimulates cytochrome C oxidase and has effects on improving mitochondrial function and visual signs of aging.
Do you want help with improving mitochondrial function? You want red light in this wavelength 630-670nm and 830-870nm.
Be sure to know the intensity of the light so you know how long to use it.
It’s been proven that red light therapy can
Second, the intensity of the light matters. Lower intensity light will have less effect and take a much longer time to benefit. Higher intensity light will penetrate the body deeper and take less time to be effective.
While there are many devices out there, we only list those for which we’ve had experience and talked with the founders and scientists in the companies.
Joovv was developed by two couples who include medical device professionals. After paying high fees for using a red light device at the spa, the Joovv was put into development as a lower cost light device for use at home. The name actually comes from a combination of rejuvenation and domain names that weren’t yet purchased.
Joovv based their light design on scientific studies of LLLT. Joovv is transparent about the wavelengths and intensity they use and have made a rugged and effective device.
In addition, Dr. Michael Hamblin is on their scientific advisory board and supports that the Joovv is an effective light for PBM.
The Redjuvenator was developed by Leanne Venier, an engineer, artist, and student of energy medicine and eastern medicine.
The Redjuvenator has many hundreds of testimonials claiming great benefits from use including healing sun sensitivity (people who always need to wear sunglasses) to healing rashes, muscle pain, and speeding recovery. Some users claim that it works well to induce sleep and cure jetlag. Leanne Venier, the inventor of the Redjuvenator, has a private Facebook page where people post their results using her devices. There are certainly lots and lots of positive testimonials.
This panel contains two undisclosed wavelengths of RED light and one undisclosed wavelength of infrared light. Leanne will not disclose the wavelengths of light that she uses. She claims that they are effective but not well studied in the literature.
Because we do not know what the wavelengths are, Leanne keeps them secret, we cannot make claims pointing back to the scientific literature. However, Leanne is very well read in the literature, the physics, and in energy healing and Eastern medicine. We believe her when she says that the wavelengths she uses are effective and the testimonials on her Facebook page and website support this.
Redjuvenator Woo Factor
Here’s where The Redjuvenator differs from all other lights. Leanne adds “quantum healing codes” and her knowledge of eastern medicine, energy medicine, and color into her light design. She claims this makes it far more effective than traditional lights that are based only on what’s been studied in the literature. Often the literature studies focus only on what NIH (National Institute of Health) funds and may exclude testing effective therapies for many reasons.
Leanne claims her panels are low EMF but did not provide any indication of how she engineered that into the panel. In my testing, the electric field was very high, while the magnetic field was lower than Joovv and the single Suana Space light and about the same as the Sauna Space EMF Sanctuary Sauna.
I have not personally used one of their lights. A friend of mine has one of their lights and it’s the one with wavelengths in it.
Are wavelengths better than 2? It’s hard to say. Dr. Hamblin says the wavelengths they use are so similar that likely the added wavelengths do not do anything beyond what wavelengths would do.
Developed by Dr. Jack Kruse and Ruben Salina, the Quantlet is an evolutionary design in wearable technology that is designed to use PBM on your wrist. We wrote an entire article on The Quantlet. We think it’s the right direction and sorely needed in our modern world. At this time, warranty and quality issues are keeping us from wholeheartedly backing the device. If Quantum Dynamics, the company selling the device, steps up quality and customer service, we will review it again.
That being said, there are many users, device quality issues or not, that swear by the life changing and healing benefits they have received from using it. The Quantlet uses frequencies of light that are critically important in ALL life, ultra-violet (UV) and infrared (IR). These two light frequencies can be captured by water and drive numerous processes in the body that maintain health. Without these two frequencies, we do not thrive, we are left open to disease and increased aging.
The Quantlet also claims to help keep the body at its preferred temperature so that it can operate more efficiently. When the body overheats due to training or disease, physical performance, and cognitive function decline.
If metal detector manufacturers what a vision of the future then drop me a line as I have a brilliant idea which will push the world of detecting into the 21st century! In fact I may make one myself.
The batter life on the Garrett Ace 250 is very good. It takes x AA 1.5v batteries which is typical. The voltage at which metal detectors use is a little discussed area, but in basic terms the higher the voltage they run on and the more power they use, the more depth they will have. From my previous experience of Electro Magnetic Fields (EMF), when you double the voltage pulse the field strength goes up by a factor of four. Bear in mind the Spectrum XLT for example uses 8.
The Ace 250 is quite a good machine for a starter-plus machine, it picks up inch diameter coins at about to inches with no real problem. The discrimination works well and you can tell iron from good finds with no real problems. The biggest issue for me was with smaller targets. Despite what other reviews that are associated with shops or affiliates etc, I found that it really struggled with small coins, roman denarius, dimes etc. On a 10mm hammered silver coin, it struggles to detect it at more than about to inches, which is pretty much on the surface or you’d miss it. Depending on where you live and what you are looking for this can be a problem. In England with 1000s of small coins it is a problem for me.
20 years ago, I found the ones I tested with a Tesoro Silver Sabre II at about inches but the Garrett Ace 250 would struggle in the preset mode and I must say that the rate of progression of metal detectors over 2years has been shocking. If you think back to an 1980s mobile phone and an iphone you will see my point. And yes before you all start shouting about budgets and market size well that does not excuse building off the back of phone tech which is obsolete in two years.
I think if you want some fun, do not want to spend a silly amount of money on one and are happy that you may miss some very small coins and rings but not bigger items, then it is a good all round metal detector for the money. I pretty sure that the Garrett Ace 250 is the best of the bench in the bracket.
I really like this meter. It takes some getting used to to get an accurate reading. It comes with a probe that connects to the meter with a wire. If the wire is not connected, all you got is a sub par RF detector. When you connect the wired probe, the probe is what detects the electromagnetic field. The red light at the top will light up when it detects something, and it will make a buzzing sound. The meter itself is a bit complicated until you get used to it, unfortunately. These run about 30 dollars.
Here are some EMF exposure symptoms to look out for
A simple test to see if you could be reacting to too much EMF exposure is to go camping for a week and completely unplug. Notice how you feel. Pay attention to your energy levels. Be aware of how you sleep. If you feel remarkably better, and then really lousy when you return home, you just might want to look into reducing your EMF exposure.
EMF exposure in children
In fact, excessive EMF exposure during pregnancy has been linked with childhood autism, ADHD, and asthma.
However, children continue to be exposed to these EMFs after birth while they are still quite sensitive.
Children absorb more radiation than adults do, so safe levels of exposure are much lower for children yet they are often exposed to EMFs at the same rate or sometimes more than adults. Children are blasted with EMFs from baby monitors, equipment in hospital nurseries and NICUs, home wireless systems and more.
Easy on the home Wi-Fi
Wi-Fi is a wonderful thing. No more unsightly wires running everywhere. No more waiting for dial up. It is also an EMF-exposure monster, so use judiciously.
Protect your devices.
Another simple step is to use some protective cases for your most used electronics.
Be smart about your smart meter.

Induction cookers 101
The increasing popularity of induction cookers can be put down to a range of benefits, including faster cooking times and energy efficiency. Induction cookers use magnetic fields to induce an electric current in the ferromagnetic base of the saucepan, which in turn heats the vessel. Although this is effectively a closed loop and the majority of the magnetic field lines go through the base of the pot, some stray fields are inevitable. These do, however, decrease rapidly with distance from the cooker.
