Ghost or paranormal investigations: Their hypersensitive nature makes them suitable for detecting unusual electromagnetic phenomena often associated with paranormal activity.
Underwater and water-related explorations: While not explicitly waterproof, the devices could potentially be used underwater if properly encased.
Energy harvesting and power generation: When connected with power cells or resonated at specific frequencies, these units can generate significant voltage, up to thousands of volts in certain conditions.
