How deep do metal detectors go?
Summary
In this article, I will share some key points about metal detectors. Metal detectors can detect objects about 4-8ʺ (10 – 20 cm) deep, but in ideal conditions, they can reach depths of 12-18ʺ (30-45 cm). Specialized detectors can even go as deep as 65′ (20 m). However, metal detectors cannot pick up stainless steel, gemstones, pearls, bones, diamonds, paper, or stone figures. Gold can be detected at a depth of around 1.5 meters with the best gold prospecting machine, but deeper depths are not realistic. The Garrett AT Gold metal detector has a maximum depth range of 40 cm for small objects and 125 cm for large objects. To pinpoint a target with a metal detector, you can pass the coil over one wind draw and imagine an imaginary line roughly the size of your coil. The largest gold nugget discovered in California was found in 1977 with a metal detector and weighed 156 ounces (4.4kg). False alarms in metal detectors can be caused by objects in the environment that emit or reflect electromagnetic fields, such as fluorescent lights, computer monitors, and structural steel. Airport walk-through metal detectors are sensitive to any type of metal, including orthopedic implants, metal plates, jewelry, keys, and belt buckles. Cheap metal detectors are not suitable for finding gold nuggets, as they are designed for coins. The biggest golden nugget ever found, known as the “Hand of Faith,” weighed 876 ounces (24.8 kg) and currently resides in a casino in Las Vegas. The depth capabilities of a metal detector depend on various factors.

What do metal detectors not pick up
Stainless steel, by definition, has a low magnetic permeability, which means that it does not produce a signal strong enough to be recognized. Other items that a metal detector will not detect are gemstones, pearls, bones, diamonds, paper and stone figures.
How deep can a metal detector find gold
A realistic depth to detect a fair size nugget is around 1,5 meters with the best gold prospecting machine on the market, the Minelab GPX5000. Depending on soil condition and nugget size a 1,5 meter depth is a realistic max depth for a large nugget. Deeper than 1,5 meters is not realistic.

How do you pinpoint a metal detector
So it's worth a dig first thing you do is pass the coil over one win draw. Yourself an imaginary line roughly. The size of your coil in this case 11 inches. So the target is going to be somewhere in
What is the most valuable item found with a metal detector
The largest gold nugget discovered in California, this famous 156-ounce (4.4kg) chunk of gold was found in 1977 in the Mojave Desert by prospector Ty Paulsen using his trusty metal detector.
What will trigger metal detectors
Multi-Zone Metal Detector
False alarms may be caused by objects in the environment that can emit or reflect electromagnetic fields. Fluorescent lights, computer monitors, and structural steel are some examples of objects that can cause interference.
What sets off a walk through metal detector
Airport walk-through metal detectors are sensitive to any types of metals, including orthopedic implants or metal plates used to treat bone fractures. Hip and knee replacements will also set off metal detectors at airports, as will any jewelry, keys, belt buckles, and more.
Will a cheap metal detector find gold
Despite what some dealers may tell you, you aren't going to have any success finding gold nuggets using a cheap metal detector. Those coin detectors might do a decent job finding coins in the park, but finding gold nuggets is a whole different ballgame.
What is the biggest piece of gold found with a metal detector
Hand of Faith
It was there that the “Hand of Faith” — the biggest known golden nugget — was discovered in 1980, weighing 876 ozs. That nugget currently resides in Las Vegas' Golden Nugget Casino. Equipped with a more expensive detector, the man who found $160,000 nugget said he's going back to see if he can strike gold again.
What makes a metal detector go deeper
Detection Depth Factors
The simple answer is "as deep as the diameter of the coil". So detectors with larger coils will detect deeper. Large targets can be detected deeper than small targets. Circular shapes like coins and rings can be detected deeper than long thin shapes like nails.
How deep do pin pointers go
Waterproof to 20 Feet: Fully submersible for shallow-water detecting, snorkeling and diving up to 20 feet (6 meters) Adjustable Sensitivity: Choice of 3 sensitivity levels. Maximum sensitivity for detection of nuggets and small targets.
Where is the best place to metal detect for old coins
Search around front porches, back door steps, walkways and driveways. Scan floors, baseboards and floor coverings carefully for lost coins. Very valuable old coins are often found between the baseboards and the floor. Interestingly, people used to hide coins behind boards in the wall and inside hollow doors.
Why don’t jeans set off metal detectors
Jeans. Jeans are fine to wear through airport security. So, don't worry, you won't be asked to remove them! Some people might be concerned that metal buttons and zips on jeans will set off the metal detectors at airport security but these metals are so small that they're unlikely to get picked up.
Will my phone trigger a metal detector
Whether it's an iPhone or Android, there's a lot of metal inside them. From logic boards to wiring and batteries, to the housing of the phone itself, there are many types of metal in a phone, making them relatively easy to detect compared to a ring or other lost object.
Will jeans set off a metal detector

How do you get through a metal detector with a vape
However, if you want to pass through a metal detector without being caught, make sure you are using a disposable or metal-free vape. These devices don't contain metal, which keeps them hidden from the detector.
Does 14k gold set off metal detectors
Yes, for the most part. Gold, platinum, sterling silver, and other fine jewelry rarely causes an alarm. That means you can wear your rings, earrings, necklaces, bracelets, and watches. The only gotcha is when your jewelry is bulky or contains a lot of metal.
Can a metal detector find diamonds
This leads to an important point: 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.
Can a metal detector detect a vape
Yes, vapes can be detected by metal detectors.
These detectors are typically used to identify the carriage of weapons or other metal objects, metal detectors are a tool more frequently being used to uncover vapes and e-cigarette devices because they can easily detect the metal within most vape devices.
Can a Pinpointer find gold
Generally, any metal detecting pinpointer will find gold metal if it's large enough. That includes gold jewellery and gold coins.
What is the difference between a pin finder and a metal detector
The major difference between a magnetic locator and a metal detector is that the former only locates ferrous metals, while the latter can locate all types of metals to locate a wider range of buried items.
Will coins set off a metal detector
Coins set off metal detectors quite frequently. There are some small metals that will pass through most metal detectors without setting them off, such as the button on your pants. Coins are not one of those metals.
How do you clean coins after metal detecting
Easily the best method to clean clad and other common finds. Place your coins into a rock tumbler with a small amount of fish gravel from a pet store. Add some vinegar, salt and lemon juice – and get to tumbling. This only takes about 30-60 minutes until you see a huge difference.
What material will stop a metal detector
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.
