Since 1931, Fisher has been the most trusted name in metal detection. This frequency is also called an induction balance because it uses both a transmitter and receiver coil that work to analyze signals. Many machines are designed for “universal functionality,” perfect for gold prospecting or scouting jewelry and coins. Novices and dedicated prospectors alike can find easy-to-use metal detectors that make the hunt simpler than ever. Track down buried treasure—coins, metallic, relics and more—with the latest generation of metal detectors.
Before buying a metal detector, it is important to consider the following factors. The best metal detector is one that suits the users’ personal needs and wants. However, for this to be achieved, the best metal detector brand has to be used. Apart from being a hobby and a sport, metal detecting can pay for itself from the sale of the found treasures.
Even if you don’t want to submerge the whole machine accidents happen and these detectors are not cheap. I like to wear a sports type T or polo that moves with my shoulders as I swing the detector. Walking over rough ground is hard work and you’re likely to be out there a while. Don’t forget to scan the pile of soil during the dig, just in case you already pulled it out. Stabbing around in the soil leads to broken objects which are worth considerably less than intact ones.
We have consistently maintained our position as one of the world’s leading manufacturers of quality walk-through metal detectors. Rapiscan® Systems’ Metor metal detectors draw on nearly forty years of design and production experience in people screening.
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 a few different technologies you should familiarize yourself with when choosing which detector to buy. Depending on how old the child is, you might want to start with a detector that’s not super heavy. Most of these machines will be PI and should be used in areas where gold is known to be found. All you need is to be hit by one wave while digging your hole, and the machine is toast if it’s not waterproof.
Pipeline metal detectors are designed for inspecting pumped liquids, pastes, slurries, high viscosity fluids and vacuum-packed products in industrial food and non-food processing applications. Highest sensitivity and reliability with small insertion space for maximum product quality and brand protection.
Larger portable metal detectors are used by archaeologists and treasure hunters to locate metallic items, such as jewelry, coins, bullets, and other various artifacts buried beneath the surface. Modern top models are fully computerized, using integrated circuit technology to allow the user to set sensitivity, discrimination, track speed, threshold volume, notch filters, etc., and hold these parameters in memory for future use. It lets you know if the metal falls within a certain group like gold, silver, or steel. VLF: Using two coils, the outer one sends a very low-frequency signal toward the ground.
The PoliceOne Police Metal Detectors product category is a collection of information, product listings and resources for researching Metal Detectors, also known as Metal Scanners. 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. If you sweep the detector above a metal object (such as this old gray spanner), the magnetic field penetrates right through it.

While most machines are designed as all around detectors for coin, jewelry, and relics, there are also specialty machines for different uses. Most new hobbyists tend to spend $150-$300 on their first detector.
You can leave your coil on the detector with the ample storage room for easy transport.
