Whether milling raw timber or using recycled lumber, this powerful and accurate hand held detector will help you save valuable saw, planer, and jointer blades by locating embedded metal before you cut. It detects nails, screws, wire, bullets, staples, tacks, and other small metal objects up to 6" deep, even in dense woods. Detector has a 5" long x 2-1/2" wide detection path to speed the lumber scanning process. It's LED Target Indicator works in tandem with one of two settings: 1) A high pitched Audio Alert for quiet conditions 2) A Vibration Alert for noisy workshop situations. Both Alerts operate with equal accuracy.
