In our opinion this is the best AFFORDABLE 3 in 1 meter available.
It measures 3 types of EMF SIMULTANEOUSLY and has a higher sensitivity setting for RF that includes sound so you can hear the frequencies. This meter detects at 50 MHz through 10 GHz. This covers FM radio stations, 3G, 4G, and many sub 10 GHz 5G signals.
Simultaneous measurement allows the beginner to understand the nature of the different frequencies much more quickly. The more experienced or knowledgable individual is able to sweep areas for problems much faster without carrying multiple meters.
A four page document of professional instructions from Shielded Healing founder Brian Hoyer will be sent with this meter on how to accurately use the various settings to maximize your effectiveness at detecting exposures.
Magnetic Field Detection
The magnetic setting is triple axis so you do not have the complications of measuring in a single axis mode and missing a magnetic field source.
Radio Frequency Detection
There is a speaker that allows you to hear the RF frequencies in the 3 in 1 mode.
This model includes a higher sensitivity RF setting where all the LEDs are used for JUST RF and the sound is enhanced.
Electric Field Detection
This model detects ambient electric field voltage differences and can alert you to hot spots in a room from items plugged into the walls or wiring in the floors, ceilings, and walls.
