Handheld Underwater Metal Detector, 8-9 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: How to use a portable metal detector to determine the size of a metal object?

Physiological research shows that human hearing is relatively dull to changes in volume (logarithmic relationship) but sensitive to changes in pitch (linear relationship). Size, which is different from other similar products, it allows us to more accurately distinguish metal objects of different sizes.

When the probe of the instrument sweeps over the human body (object), if it emits a relatively low sound, and the sound will gradually disappears after the probe stays above the sounding place, we can determine that it is a small piece of metal, such as a belt buckle, Zipper etc. If the sound is very sharp, even if the probe is stopped, the sound is still continuous, it must be a larger piece of metal, such as a dagger, pistol, etc.
