9 Function Metal Detector With Arm Rest

This metal detector can easily find coins and other valuables hidden in beaches or in your own backyard. Features include individual tones for specific metal types and an arm rest for operator comfort.
Metal detectors are devices designed to find metal buried under dirt, sand, grass, and even in bodies of water. Metal detectors work by creating a magnetic field around the electrical search coil, which spreads out to an average depth of about 10 inches. If conductive material is within the detector’s range, the electromagnetic signature of the material disrupts the magnetic field. The detector’s visual and audio alerts let you know you have found something.Get more news about Metal Detector,you can vist our website!
Metal detectors are categorized based on how they are used and the items they detect. There are three main types of metal detectors: Very low frequency (VLF) detectors, pulse induction (PI) detectors, and specialty detectors.
Very low frequency (VLF) detectors are the most common and affordable types of metal detectors. A VLF detector has two coils: a transmitter coil that creates the magnetic field, and a detector coil that senses any disturbance in the field created by conductive materials.

In addition to being inexpensive and easy to find, VLF detectors are lightweight and durable, which makes them great options for beginners and children. This kind of metal detector is typically used to find coins, jewelry, relics, and other metal deposits. Though there are water resistant and waterproof VLF detectors on the market, pulse induction (PI) detectors are better for underwater metal detecting.

Pulse Induction (PI) Detectors
In contrast to the VLF detector’s two-coil design, Pulse induction (PI) metal detectors have just a single coil. This one coil transits the magnetic field and detects conductive materials. PI detectors’ single-coil design is less affected by ground mineralization than VLF detectors, which is why it’s better to use PI detectors when searching beaches, rivers, or underwater (if you have a waterproof detector). PI detectors are not the best metal detectors to use in cities because they cannot discriminate between iron trash, like nails, and treasures like coins or gold. Another disadvantage of PI detectors is that they are more expensive than VLF metal detectors. Novice metal-detecting hobbyists may not want to make such a substantial investment.
Metal detecting is a great hobby for individuals or for families with children—some dedicated and skilled practitioners even pursue it as a professional career. The best metal detector for you will depend on how and where you want to use it, and whether you want a simple, straightforward model or one with lots of bells and whistles.
