Finding Metal With Metal Detectors

David Marc Fishman asked:

The main part of metal detectors is the control box, shaft, and search coil. Control box which has speaker, batteries, and microprocessor coordinates all activities. To protect the food source many companies use metal detectors to check for metal contaminates in the food, and some drug companies use the metal detectors to check for the same thing in drugs.

Besides metal detection, a walk-through metal detector includes and interface for an operator and a control unit plus environmental tolerance, electro magnetic compatibility, and the assurance of quality control. The control box is the brain of a metal detector. The magnetized metallic objects under the ground send a signal to the control box. Metal detectors that are used in mining need to be compact because of the space restrictions so the control unit and the search coil are integrated into a single unit.

This disk comes off the shaft at an angle, which allows it to be held parallel to the ground. Hand held detectors come in various types, professional, commercial, all-purpose, gold metal, beach and metal that is a relic. Many people use metal detectors to comb the beach for treasures, people are looking for coins, or any other type of metals that might produce a wealth of income. If you are walking along a beach you might come across many people with their instruments looking for these treasures. Since 911 security has gotten tougher and many airports and schools have turned to metal detectors, as well and government buildings, hand held metal detectors are often an important part of security procedures.

A great method of locating and preventing the use of dangerous items such as handguns or knives is the hand held metal detector. They are hand held security metal detectors and walk through metal detectors. Walk over or hand held models of metal detectors are normally used in airports.

Best rated walk through metal detectors have high target selection, low rate of false alarm, consistent detection, and a two way directional system. Cheap metal detectors are available in hand held, waterproof, and walk through models. Walk through metal detectors offer quick and effective processing.

Underwater metal detectors can cost around $400-$600. Underwater metal detectors are widely used to locate metallic objects under water. Underwater construction companies use underwater metal detectors for pipeline or cable locating functions. Some of the underwater metal detectors can adjust the search depth.

Advanced security metal detectors use low radiation x-rays for screening. Many metal detectors have microprocessor technology to check for coarse grained food in cornflakes, popcorn and noodles. Advanced gold detectors can also resist dust and moisture. Some of the advanced gold metal detectors have three modes for speed tracking.

Usually, the price of a metal detector starts from $65. Some sites offer price discounts.

Most sites provide a price list for metal detectors. The price of metal detectors may vary, based on features and functions. If you are just starting out it is a good idea to purchase an inexpensive model before sinking the dollars into the hobby.

Metal Detectors Are Used For So Many Purposes

How To Get Started with a Gold Detector

Alan Jones asked:

When we really want to do something new it is easy to get pumped up and excited, the reality then kicks in on the challenges of getting started with our newly found subject. To get started with Gold Detecting the first move is to research what tools and equipment are needed, this is where it starts to get very confusing. There are so many different types of Gold Metal Detectors on the market from various manufacturers and suppliers at a wide range of prices, we can easily put off doing anything at all.

So where do we start, well sometimes it’s a question of ‘just doing it’. A good way to get up and running is to buy a very basic Gold Detector and learn by practicing your new found venture. The quality of the Metal Detectors supplied by our leading manufacturers is generally excellent, the difference between one product and another is mainly in the specification and of course the price. Compare two leading brands with similar specifications and the price and quality will usually be similar. Also look out for discounts on many models especially the lower priced ones which are attractive to people getting started.

Basically the same technology is used for most gold detectors. There many different types and models but they are all based on the same electromagnetic technology. When a magnetic field inside the gold detector is created it reacts with the magnetic field within metal on the ground. The metal detector can analyze this reaction and convert it into a signal that shows that metal has been located nearby.

Tuning is a very important factor of gold detectors  The gold detector has to be calibrated correctly to properly receive the signals from the ground, this can vary depending on what you are prospecting for. This process may need to be monitored every few minutes depending on the type of gold detector.

How you use your gold detector has a great bearing on your success rate. With some gold detectors a slow rotating action is required and others may prefer a faster action. For best results you should read the guidelines in the manufacture’s manual and follow their recommendations. Detection depth is not easy to specify by the manufactures due to various factors including ground type and moisture. It is usually not that important as you are just as likely to find your treasure close to the surface, it can also save a lot of digging!

The other key difference in the specification is the frequency. Low signal frequencies between 5-10kHz and 15-20kHz are used for most gold detectors. The reason for that is that if you are looking for objects like coins and items of jewelry then low frequencies between 5-20KHz can be used as low frequencies tend to go deeper into the ground. The multi frequency gold detectors tend to be more expensive and are therefore used by the more established gold prospectors.

So back to our original discussion, look around for a basic low cost Gold Metal Detector from one of the leading brands and just get out there and enjoy learning about Gold

Detecting, you never know what treasures you might find.
