The delivered digital metal detectors utilize propelled SMD advancement. These are integrated with ultrahigh stability and sensitivity to detect metal material on a person. They are also integrated with a battery charger for a worker to recharge the battery when it gets drained. Please come with visual symbols for battery low, power on, battery charging on, and metal detection. Our digital metal detectors also have an audio indication and vibrator that turns on when a metal is detected. They do not influence magnetic tapes and Cardiac pacemaker. These have ABS molded structure that offer low weight, lifted strength and rigidity features.
