The Lumber Wizard 5 Woodworking Metal Detector is designed to detect small metal objects hidden inside new or used lumber, such as nails, screws, bullets, wire, and other metal fragments that can damage expensive jointer, planer, and saw blades or cause serious injury. The device is easy to use with one hand and features automatic calibration every time it is turned on, ensuring precise detection strength and better false-positive rejection. The Lumber Wizard 5 has a durable, sturdy plastic casing, and comes with a laser line indicator that projects a red line onto the scanned surface when metal is found, helping users pinpoint the exact location of the metal object. The device is not affected by the moisture content of wood and can quickly scan any size wood with its 6" wide scanning area. It requires one 9-volt battery, which, when fully charged, can last for weeks of daily use. The Lumber Wizard 5 comes with a 1-year warranty and measures 15" in length, 3-1/8" in width, and 1-1/8" in height, with a weight of 13 oz.
