Feature:1. 4 Depth Range Class: automatic material classification classifies magnetic metal(8cm), non-magnetic metal(5cm), AC cable(5cm), and wood(2cm) for accurately location.2. Big Sensor: adopts with high sensitivity sensor to improve the detecting accuracy.3. Dual Alarms: indicator light change to red and buzzer sounds up once detecting metals.4. 3 Indicators Lights: according to the strength of the detected metal, the indicator light changes among red(strong metal signal), green(no metal) and orange(weak metal signal).5. Large Display Screen: 2.2-inch large LCD screen with backlight display the measured data clearly and intuitively.6. IP65 Protective Grade: protect the detector from dusty environment, suitable for various working conditions.7. Fluff Pad Design: 2pcs fluff pads increase the flatness of the detector thus enhance the stability during detecting.Specification:The wall detector can detect metals(magnetic and non-magnetic), wood and live cables hidden in walls, ceilings and floors (the wall, ceilings and floors refers to concrete, tiles and boards.)Features:4 Depth Range Class: automatic material classification classifies magnetic metal(8cm), non-magnetic metal(5cm), AC cable(5cm), and wood(2cm) for accurately location.Big Sensor: adopts with high sensitivity sensor to improve the detecting accuracy.Dual Alarms: indicator light change to red and buzzer sounds up once detecting metals.3 Indicators Lights: according to the strength of the detected metal, the indicator light changes among red(strong metal signal), green(no metal) and orange(weak metal signal).Large Display Screen: 2.2-inch large LCD screen with backlight display the measured data clearly and intuitively.IP65 Protective Grade: protect the detector from dusty environment, suitable for various working conditions.
