Uncover hidden treasures or ensure safety with this highly sensitive MD-3003B1 Metal Detector. You’ll appreciate how effortless it is to use, with no adjustments required. Despite lowering a 3.9V battery to around 7V, this device maintains a reliable detection distance. It’s energy-efficient too, offering more than 40 hours of continuous operation.
The metal detector gives you the flexibility to choose between an audio alarm or a vibration alert. Don’t worry about running out of power mid-search, as a consistent alarm or vibration signal will remind you to swap the battery. To ease usability, it features power-on and power-off alerts, with high and low sensitivity options. There’s also an external charging jack for power back up.
Specifications:

Operating the MD-3003B1 metal detector is straightforward. Insert a 9V standard or rechargeable battery, push the on/off switch until the green LED illuminates, and start detecting! For best performance, adjust the sensitivity until the red LED lights up, accompanied by a continuous audio tune.
Hold the detection face 10-30 mm above the area you’re scanning, and keep moving it to detect any metallic presence – which triggers an audio alarm and a red light. If the detector is held stationary over a metal object, the detection signal reduces, hence constant scanning is recommended.
Package includes:
