Record the units with the numbers
A magnetic-field value cannot be compared directly with an electric-field value. Note the mode, unit and location each time. Data Hold freezes a display for reading; it should not be assumed to create a saved session log.
Before you buy
The retailer gives conflicting magnetic alarm thresholds. Check the supplied manual for the settings, and do not use an alarm color as a health or safety verdict.
This overview is based on published product information, not a hands-on HauntGears test. Confirm the exact model, current specifications, included accessories and seller terms before ordering.
Using the device during an investigation
Make baseline observations before a session. Note nearby wiring, appliances and transmitting equipment, then repeat unexpected readings with the device in the same position. A response alone does not establish paranormal activity or certify environmental safety.
Read our EMF meter field guide, compare EMF meters, or browse digital recorders for documenting your observations.
