Feature:
Imported low temperature IC and the latest circuit design to achieve the most complete functionality with the smallest size Advanced push and pull button design, the one-button operation can realize the conversion between sound and light and mute/vibration operation The 9V battery is reduced to about 7V, with constant detection distance and power saving, which can be used for more than 20 hours continuously
Humanized push-pull battery cover design makes it easy for customers to replace the battery without any tools. Eco-friendly and with fire retardant materials, moisture-proof and dust-proof design Can simultaneously detect magnetic and non-magnetic metal, and with excellent detection sensitivity on copper and aluminum materials too. Three indication by light: power normally on (green), alarm light (red), battery power is in undervoltage state (yellow). With charging port, plug and charge, convenience charge at any time
