Today, finding some rare or valuable item with a metal detector is a real treasure. Among 'detectorists' there are both hobbyists and professionals. It is no secret that with a metal detector you can find coins, relics, gold, and other interesting archaeological valuables. There are entire teams that professionally search in areas where battles once took place. Additionally, many have surely noticed hobbyists with metal detectors walking along local beaches in search of lost valuable items. This is what distinguishes hobbyists from professionals. Regardless of how you plan to use a metal detector, it is important to understand its features when choosing one.
Types of Metal Detectors
All metal detectors are divided into groups and certain parameters that correspond to different methods of use.
Soil Metal Detectors
Designed for searching for various types of ammunition and mines. This type is popular for finding jewelry, old coins, and gold. The thing is, soil metal detectors can detect even very small particles of gold that may be up to a meter deep.
For those who love antique items, this is an excellent device capable of finding them among various other metal debris.
Deep Metal Detectors
This type is designed for searching for treasures and military items. A deep metal detector does not detect small objects; it "picks out" larger ones.
Underwater metal detectors
This is a type of device that allows searching at depth. Deep-seeking metal detectors differ in terms of depth capability, which is important when choosing one. Given the purpose of the device, it is well-sealed; however, its service life is not very long. After just a year, the sealing properties weaken, and the metal detector becomes unusable. Another important detail is that this model does not have a display.
Nuances
Working with a metal detector can take several hours, so it is extremely important to choose a device with a light weight; otherwise, prolonged use will be impossible due to hand fatigue.
When working at depth, scuba gear is not required; a deep-seeking metal detector comes with special headphones that prevent water from entering the ears.
Deep models are considered for searching for ammunition and treasures left over from the war at depths of one and a half meters or more.
Which parameters should you pay attention to?
The ability to separate metals, distinguishing them from ferrous and non-ferrous metals. Additionally, an important parameter is the distance between these metals. The smaller the distance, the better the metal detector will work in selecting the "desired" object.
The operating sensitivity can be minimal or maximal. In the first case, the device will be sensitive to larger objects, and in the second – to smaller items.
Ground balance allows for taking the value of the soil into account in the readings, removing it or adding it to locate certain objects.
An interesting and convenient parameter is the scanning speed. With its help, information about an object can be obtained as quickly as possible, indicating its more precise location. This parameter is not available on all devices, only on more expensive models.
A metal detector is an interesting device for amateurs and an important, deliberate tool for professionals.
