For the Earth Goddess — trust the earth, but verify the mat.
A grounding practice is only as good as its conductivity. This pocket-sized tester checks that your earthing mats, sheets, and wristbands are actually conducting: touch the probes to the material, and if the light comes on, the current flows. Peace of mind in about four seconds.
Remove the cap, touch the prongs to your grounding gear, read the light. It travels well, too — perfect for checking hotel-room setups without ceremony.
Battery-powered conductivity tester · 3 LR41 batteries pre-installed (easy cap-off replacement) · Compact and portable · Works on grounding mats, sheets, and wristbands. Please note: this is a conductivity tester, not a grounding verification tool — it checks whether a material conducts electricity.
