We recommend placing the tester along the spine of the mat. There are two PEMF cores in the Go Mat and four PEMF cores in the Pro Mat. These specific spots will pick up the vibration of the metal pallet.
We advise testing these areas on all four PEMF levels. Levels 1-2 should produce quicker vibrations whereas levels 3-4 have slower vibrations.
The cores are located at the center to optimize the transmission of the frequencies to the rest of the body.
