    "device_name": "One-hand Adjustable Divining Rod",
    "goal": "Increase the sensitivity and precision of dowsing/detection of subterranean substances, water, minerals, and other environmental phenomena.",
    "problem_addressed": "Traditional dowsing rods have low and and poor reproducibility, making it difficult to locate specific spots or regions in space with confidence.",
    "concept_summary": "A one-hand test rod consisting of a conductive metal tube handle, a flexible indicator wire, and a slideable conductive tuning element inside the tube. By adjusting the tuning element, the rod forms an electric resonant cavity that amplifies deflection of the indicator tip when it encounters a target region. The device is claimed to provide reproducible, highly sensitive detection of water, minerals, and other geobiological stimuli.",
    "detailed_description": "The invention comprises a cylindrical conductive tube (e.g., copper) that forms the handle, a straight indicator wire (e.g., brass) attached to a conical helix tip, and a longitudinally slideable conductive tuning element (copper or brass) inside the tube. The tuning element can be locked in position with a knob and stud mechanism. When the indicator tip is brought near a region of interest, the tuning element can be moved to a resonant position, causing the tip to vibrate or spin. The inventor reports that different resonant positions correspond to different spatial spots and that the deflection is reproducible in practical tests. The device is intended for tracing water, mineral resources, and other \"irritating stripes\" on the ground, as well as for therapeutic applications when combined with textile sleeves containing copper conductors.",
