Chapter 3: Metal Detection: This useful (though slightly dated) 1999 review comes from a US Department of Justice report on «The Appropriate and Effective Use of Security Technologies in US Schools,» and includes a look at walk-through detectors, hand-held metal detectors, and X-ray baggage scanners. The orientation of the object: objects buried flat are generally easier to find than ones buried with their ends facing downward, partly because that creates a bigger target area but also because it makes the buried object more effective at sending its signal back to the detector. The size, shape, and type of the buried metal object: bigger things are easier to locate at depth than small ones. If you sweep the detector above a metal object (such as this old gray spanner), the magnetic field penetrates right through it.

They’re also great for doing both saltwater and all around detecting without having to buy two machines. These are best if you’re serious about detecting and have the budget to back it up. Multi-frequency (MF) detectors are typically machines that go for over $1,000 and most commonly found in the high-end Minelab detectors.
There are different varieties of metal detectors one can choose from depending on the budget, location, and the treasures being hunted. It is fun and enjoyable exploring outdoors and hunting for valuable treasures. Understand what the symbols and tones mean, and figure out the best discrimination setting – one that ignores iron but picks up coins. If that isn’t practical enough advice for you, then I’d say get to know your machine.
Some experienced detectorists are willing to share their best hunting grounds. Go to places where you’re more likely to find objects such as the beach or a park, and do your research online. Lots of debris lodges beneath the coil cover such as soil, stones, sand, and even a build-up of moisture.
It’s your job to drop tin foil, nails, coins and gold in your yard and play with discrimination. As you increase discrimination the machine will ignore other metals like tin foil, can tabs, nails, and coins. Low discrimination means all metal including soil minerals, are picked up. A machine with ground balancing detects what type of ground you’re on, and eliminates the unwanted minerals in response.
Metal detecting is only allowed in areas of the park open to the general public (this does not include reserve use or service/maintenance areas) during standard park hours of dawn to dusk. Metal detecting is only allowed in public areas and may be prohibited in areas such as reserved shelters, sport fields, etc. Safeline metal detection solutions offer maximum detection sensitivity with minimum false rejects. The metal detector is periodically verified (typically at 6 to 12 month intervals) to ensure compliance and demonstrate due diligence. A well-executed and carefully carried out installation phase is the foundation of worry-free and efficient use of the metal detector.
This is my current choice for when I go out metal detecting if you’ve been following this blog for awhile you know I started out with the Ace 250. There are many variables that you need to consider when looking to purchase a detector, read our metal detector buying guide at the bottom for more help.
White’s engineers know what frequencies you’re most likely to find dropped money on, but if you fancy tuning it up even more you can manually adjust the discrimination capabilities. Turn on the pre-set function and you can start hoovering up those coins straight away with its massive 10″ coil. It’s a pricey piece of kit, but you won’t find better for coin hunting.
Metal Detector app is simple to use, just open it and move it around. One of the most sensitive metal detectors on the market, this metal detector identifies metal objects embedded in wood or hidden behind walls. In addition, we provide a lightweight hand-held metal detector which can be used in conjunction with Metor walk-through metal detectors or separately. Rapiscan® Systems provides Metor metal detectors for indoor and outdoor use, for high sensitivity as well as high discrimination demands.
If you plan to do most of your hunting in and around salt water, you’ll need a specialty machine. For all purpose coin and jewelry hunting, stick to a single frequency VLF detector when first starting out. These are built more for salt water hunting and gold prospecting. This may be the biggest factor of them all, especially https://metaldetectorshub.com/ when you’ve never tried a metal detector. CEIA combines the benefits of both cutting-edge metal detection and ferromagnetic detection functionality that automatically filters and suppresses alarms for non-threat items without compromising the required threat detection capabilities, ending false alarm fatigue and guesswork.
Its light, ergonomically designed, easy to swing and sturdy enough for the more professional hobbyist. This package also gives you free headphones, a search coil cover, and an ACE environmental cover-up. High-frequency metals such as gold register a high reading whereas low frequency like iron will fall lower on the scale.
