Handheld Metal Detector, 4-4.5 cm Sensitivity Distance

Q1: Do handheld metal detectors work?
A1: Handheld metal detectors are useful tools for a security guard that can be used in various settings, from airports to schools. These devices are designed to detect the presence of metal, which makes them ideal for finding hidden metallic objects like weapons or other contraband.

Q2: How deep can a handheld metal detector work?
A2: Most metal detectors can detect objects about 4-8" (10 - 20 cm) deep. In ideal conditions, a mid-range metal detector can reach 12-18" (30-45 cm) underground. Some specialized detectors can go as deep as 65' (20 m).

Q3: Will a metal detector find a diamond?
A3: Metal detectors will not detect non-metal items such as gemstones, diamonds and pearls. What a metal detector can do is lead you to indicator minerals, which are used by prospectors.

Tips: What will a metal detector not pick up?

Metal detectors work on electromagnetism. This means that they send out electromagnetic fields and listen for any waves that come back from items with electrical conductivity.

Metal detectors have a tough time detecting metals like stainless steel, which have very poor electrical conductivity. Stainless steel has low magnetic permeability, which means it does not produce a signal strong enough to be detected. Other items that metal detectors won’t be able to locate include:

• Gemstones
• Paper
• Pearls
• Bone
• Stone figures
