Many people worry about constant exposure to electromagnetic fields (EMFs), citing health concerns such as headaches, insomnia, and other ailments. Hoping to detect when fields are elevated, they turn to using EMF meters. Unfortunately, EMF meters are inconvenient to use, not to mention often inaccurate and costly.

Introducing the EMF BeaconTM, a patent-pending device that monitors EMFs 24 hours a day, without requiring batteries or user interaction. Packaged as either a small acrylic keychain or in a plastic sleeve, this state-of-the-art device continuously monitors the ambient environment, shining a bright red light when EMF levels are elevated. Never be unaware of excessive high-frequency EMF energy again!

Described as "two parts engineering and one part magic!" The EMF Beacon harvests ambient EMF energy to power its circuitry. It’s not a scam; it really works! The EMF Beacon has two antennas that work together to monitor the 2.4 GHz and 5 GHz frequency bands. Together, they detect EMFs from wifi, Bluetooth, microwave ovens, cordless phones, baby monitors, car alarms, video transceivers, and more!

Please read the FAQ's before purchasing.

Available in green or black as either a keychain or in a plastic sleeve.

Shipping & Returns

$5 Flat Rate Shipping in USA

Additional shipping costs outside the USA. Prices do not include foreign import (duty) fees. We now only ship internationally with USPS to help reduce import charges that other carriers charge.

We test each EMF Beacon before shipping, but If you receive a defective unit, please contact sales@emfbeacon.com for a replacement.


The EMF Beacon measures approximately 1" x 2".

Customer Satisfaction

If you're unsatisfied with your order, please write us at sales@emfbeacon.com. We will do our best to make it right without a hassle. Please keep in mind that EMF Beacons are expensive to manufacture, so please treat us with the same consideration you would want if you were operating a small business.


The EMF Beacon is a unique device that uses ambient EMF energy in the 2.4 GHz and 5 GHz bands to power its circuitry. No batteries are ever required. It is designed to light when the field levels exceed about 1% of the ICNIRP/IEEE maximum recommended levels. Most areas in your home will not exceed these levels. Also, it will not light from power line emissions because those are at much lower frequencies and drop off very rapidly with distance. One way to see your device working is to hold it near a Wifi router or microwave oven.

Growing a small business is very hard work, and we absolutely value and respect every customer.

Thank you in advance for your continued support!

A Few Interesting Facts

1. Electromagnetic fields (EMFs) radiate from anything that generates, consumes, or transfers electricity.

2. The WHO/International Agency for Research on Cancer (IARC) classifies non-ionizing radiofrequency electromagnetic fields as possibly carcinogenic, based on an increased risk for glioma, a malignant type of brain cancer.

3. EMF intensity drops off quickly with distance. For every doubling of distance, EMF power drops by a factor of four.

4. Low-frequency EMFs, such as from power lines, require special high-permeability materials to block. Fortunately, low-frequency EMFs are rarely above ICNIRP recommended max levels of 83 micro Tesla.

5. High-frequency EMFs, such as from routers and cell towers, are easy to block with metal barriers but are also able to squeeze through very tiny apertures. Unfortunately, EMFs from high-frequency sources often exceed the ICNIRP recommended max levels of 10 watts per square meter.

6. The most effective method of reducing EMF exposure is usually to put distance between you and the source. To do that, a device like the EMF Beacon that warns of elevated fields is extremely helpful.

We Value Our Customers

  • Shipping

    Ships to anywhere in the USA for a flat rate of $5. Shipping also available to Canada and other countries for added cost. We ship Delivery Duty Unpaid (DDU), i.e., price does not include import fees outside USA. We now only ship by USPS due to the much higher import fees charged by other carriers.

  • 100% Product Tested

    To ensure performance, we test every EMF Beacon and examine every Stealth Tech Hat prior to shipping.

  • Satisfaction Guaranteed

    If you are unsatisfied with your order for any reason, write us at sales@emfbeacon.com. We will do our very best to make it right without a hassle.

  • Developed In USA

    The EMF Beacons and Stealth Tech Hats were developed in the USA for use anywhere in the world. They help to reduce EMF exposure from nearly all high-frequency EMF sources.

  • Returns

    When returns are requested and the product is not defective, we ask that the customer cover shipping costs. We test every EMF Beacon and examine every hat prior to shipping.

  • Questions?

    Please don't hesitate to write us at sales@emfbeacon.com with any questions you might have.
