Metal detectors are categorized based on how they are used and the items they detect. There are three main types of metal detectors: VLF, PI, and specialty.
Very Low Frequency (VLF) 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.
Fast and efficient detection is what most hunters look for. You don’t want to spend your entire day walking around in circles, so it's better off choosing a product that alerts you as soon as it picks up a signal.
The sooner you receive this alert, the faster you'll find your target. If you're short on time, this is a must-have feature. Besides that, a faster process enables you to move onto the next target once you uncover something, especially if it's not what you were searching for. For the most comprehensive experience, select a detector with adjustable speeds.
It turns out that metal detectors are not cheap. A good entry-level machine will still be expensive, and they quickly skyrocket from there. So if you’re planning on buying one, make sure it will work for your needs.
The metal detectors need to be able to separate the items underground. There are a lot of different things in the soil, including iron inside rocks and valuable coins. Differentiating is usually done with either Target or Tone ID.
Metal detecting is becoming increasingly popular and many more people are starting to take it up as a hobby. Of course, for metal detecting, the most important piece of equipment you will need is a metal detector. However, picking the right one can be tough with so many on the market. Below we have made a list of the most important features to look for in a metal detector.
The size of your metal detector can affect how you use it. For example, a smaller coil will help in high trash areas where larger coils are recommended for deep searching. In terms of overall size, the handle and length of the metal detector should fit the user. If a child is using it, you will want it to be lighter for instance.
If you enjoy hunting for treasure in your spare time, a metal detector is probably a necessary tool. Traditional, full-size metal detectors are often not sensitive enough to show you where the next treasure is located, which can lead to lots of unnecessary digging. A handheld metal detector can help you solve this problem and find your next treasure hunt.
A handheld metal detector is a small and compact device that can be carried in your pocket. It operates on a battery and can detect the location of an item once a larger metal detector has detected its general area in the ground. Some handheld metal detectors are also effective for scanning drywall, wood, plaster, concrete, tile, paneling, stucco, and other non-metallic surfaces for studs, rebar, plumbing, ductwork, screws, and nails.
