EMF Detector — sense electromagnetic fields up to 30 feet away
A battery-operated STM32 detector that reads changes in electromagnetic force with a 30 ft range — the ghost-hunting gadget we manufacture at 10,000 pieces a month.

EMF sensing
Reads electromagnetic force around the device with high sensitivity.
30 ft range
Detection reaches a full 30 feet from the device.
Change-based detection
Triggers on changes in EMF — steady fields stay quiet, anomalies don't.
Scan mode
A dedicated scan mode for sweeping rooms — ghost hunters welcome.
Battery operated
Fully portable — no cords in the haunted house.
Volume manufacturing
10,000 pieces a month, fabricated and tested in-house.
