This is our Professional Metal Detector which can be used to locate valuable metals, such as silver and gold to coins and other metal household items. It is the perfect search tool to use on the beach, in forests, fields, farmlands, and to simply locate cords, wires, and nails within your own home! Many of our customers have messaged us claiming that it is very suitable for high-speed cable detection in walls, ceilings, and floors along with finding nails hiding in the grass or on their driveway that could do some damage if not found. This has an adjustable volume and you can attach headphones (not included) via the Earphone Jack labeled “EAR,” to hear better in noisy conditions, such as a beach or construction site. When metal is detected, the metal pointer will swing to the right to show that there is metal underneath the detector. You can also use the included Waterproof Search Coil to find metal objects within water over 3 feet deep when the detector is fully extended.
