- Low power consumption: operates with 1 x 9V 6F22 battery, enabling extended use between replacements. The device uses visual alerts to indicate status: yellow LED signals a detected object, flashing green LED indicates the machine is starting to work, and flashing red LED warns of low power. - Flexible alarm options: choose between two alarm modes to match your environment. Audio mode uses a buzzer and red indicator light for clear audible and visual alerts. Vibration mode uses a vibration alert along with the red indicator light for situations where sound is undesirable. - Wide detection range with adaptive sensitivity: detection distance is 3 to 20 meters. Sensitivity changes based on the size, volume, density and surroundings of the detected object, so performance adapts to different targets and environments. - Excellent workmanship and user comfort: the device features a beautiful, streamlined design with a lightweight, compact form. High sensitivity is paired with a comfortable build for extended use. - Scenarios and applications: - Recreational treasure hunting on beaches or parks to locate coins, jewelry, or other metal objects. - Construction and maintenance sites to detect buried metal components such as rebar, tools, or debris. - Field exploration or surveying where adjustable alerts (audio or vibration) help you stay informed in noisy or hands-busy conditions. - Key attributes at a glance: - Battery: 1 x 9V 6F22 required - Indicators: yellow LED for detected object, flashing green LED when powered on, flashing red LED for low power - Alarm modes: audio (buzzer and red light) or vibration (vibration and red light) - Detection range: 3-20 m - Sensitivity: varies with object size, volume, density and environment - Build: streamlined, lightweight, compact, high sensitivity, comfortable to use - Consistent with original specifications and functionality: this description reflects the intended brand, model features, and performance without adding or omitting elements from the original product details.
