What is the depth of a metal detector?
Most metal detectors can detect objects about 4-8ʺ (10 – 20 cm) deep. In ideal conditions, a mid-range metal detector can reach 12-18ʺ (30-45 cm) underground. Some specialized detectors can go as deep as 65′ (20 m).
Are there metal detectors that show images?
3D Imaging Systems: The engineering team at Nokta Makro Metal Detectors has brought to life the Nokta Makro Invenio Pro Pack Smart Metal Detector and 3D Imaging System. This device will show realtime image scans right before your eyes. Gold, Silver and other Valuable metals are shown in full color on a color display.
What are the parts of a metal detector?
An industrial metal detector consists of four main components: the sensor, the control, the signal processor, and the output device.
How many types of metal detectors are there?
There are generally three types of metal detectors for different purposes—land-based coin and relic hunting, beach and underwater detecting, and prospecting for gold.
How does the metal detector work?
How Do Metal Detectors Work? Metal detectors work by transmitting an electromagnetic field from the search coil into the ground. Any metal objects (targets) within the electromagnetic field will become energised and retransmit an electromagnetic field of their own.
Can metal detectors detect different metals?
Metal detectors detect iron, nickel, copper, brass, aluminum, tin, lead, gold, silver and bronze. General-purpose metal detectors can find buried metal objects such as jewelry, coins and other metal objects. “Discrimination” is a process that distinguishes between different metal targets or alloys.
What are the different settings on a metal detector?
Metal detectors use two different types of frequencies: Very Low Frequency (VLF) and Pulse Induction (PI).
- Very Low Frequency (VLF)
- Pulse Induction (PI)
- Turn Up the Sensitivity Setting.
- Swing Closer to the Ground.
- Reduce Discrimination Setting.
- Know Your Detector’s Settings.
- Try Different Swing Speeds.
- Use Headphones.
