Underground metal detectors sense

  About the depth of underground metal detectors: Any product has a standard, this product marked maximum depth, is defined as the enterprise standard products with a 60 × 60 × 1.5 (cm) of aluminum sulfate buried in the soil of the measured Results (Executive Standard: Q / XHT 001-2008). That is: the greater the depth of the tested metallic objects deeper, more superficial exploration of the smaller metal objects tested. You like to buy a car, the car's nominal maximum speed of 300 km / h, does not refer to any road can run 300 km / h, which means that in order to go in a particular (detection limit) road environment This maximum speed. Description This is a reasonable hope that we understand this standard scientific truth, not to get a ring when big things have to probe into the maximum depth. THX

Examples probe

For example, in an old house in search of deeply buried relics buried underground for a long time due to the wide variety of discarded metal debris such as nails, wire, old locks, pots debris ...... and so on, these something larger signal will be issued in this case, the first metal furniture should be moved out of the house and land balance archives proved that metal debris and removed, after careful work, the shallow soil layer After the metal items are dug up to search the depth of the site.

Detection work is a meticulous and arduous work, it requires the operator to have patience, confidence and perseverance. Clearly not capable of any probe underground metal object is displayed, it can only bode probably position of the metal target, to be able to find exactly what they need, but also requires the operator to have a wealth of experience, according to the instrument Reaction careful analysis to make the right judgments.

Underground metal detectors frequently encountered problems:

 Q: Why were not up to the actual probe the depth of the subject of the instrument?

A: All the metal detection equipment to detect the depth of the probe with the metal by size, shape, weight, they have a great relationship, in general, the larger the area, the greater the number, the greater the corresponding probing depth; on the contrary, the more area small, fewer the number, the smaller the corresponding depth. The depth of the subject of the instrument, the maximum depth according to industry standard products in the best case that can be achieved. Under different circumstances soil probing depth will be different, such as the soil is wet or high density and so the case will be weakened by the signal strength of the metal probe to reduce the depth of the instrument. In addition, at low power, transmit power shortage situation will decay detection depth, in this case, please replace the battery.

Q: how to get the best detection results?

A: In the case of metal buried in the soil is dry or distant era will make the probe to enhance the effect. The farther the deeper depths of metal buried era. Because the metal buried in the ground a long time gradually oxidized to produce metal rust to spread around and the surrounding soil react to produce a strong magnetic field, the area of the metal increases, also increases the strength of the signal. The more time passes, the greater the signal strength and depth probe will be deeper!

Q: Maintenance of the instrument need to pay attention to what?

A: Do not probe in the rain, because the instrument itself is not waterproof, the circuit board if the water could cause a short circuit or malfunction in other areas. Do not have time to remove the battery, because the battery a long time on the instrument may be due to leakage and corrosion circuit board. When they do not prolonged dry place to save.

Q: underground metal detectors in the end be able to explore more deeply?

A: The depth of underground metal detector and the detected metal objects, shapes and probe related to the soil, the same detector at depths of different regions is completely different, because of underground metal detector is based on the geological characteristics of the design Therefore in the air (that is vacant) is undetectable depths of underground metal detectors, metal detectors and the earth has a magnetic induction balance to achieve the best detection results when, hanging in the air is not up to magnetic induction balance! For example: If the float 50 centimeters can detect silver, then if this gold silver buried in the ground, the probing depth will be greatly increased, and the longer the era burial, the easier it is to detect, because the metal embedded in a long time Underground will gradually oxidized to produce metal rust to spread around and the surrounding soil react to produce a strong magnetic field, the metal increase in area, but also increase the signal strength
