How to adjust the sensitivity of the metal detector
Happy owners of a new metal detector are often full of enthusiasm and ready to immediately rush into battle. However, the novice treasure hunter immediately has questions about the settings of his device, because it is difficult to understand how and what exactly to set up, and on what depends on the correctsetting of certain parameters. Setting up a metal detector is very subtle and subjective. Most of the settings each user chooses for themselves individually, in accordance with their needs, tasks and features of the search. Their accuracy depends on the experience of the search engine and is achieved through practice and experimentation. In addition, each metal detector has its own specific characteristics, and therefore the general layout of settings for all models does not exist.
An important component of the metal detector setting is its sensitivity, which directly determines the depth of the detection of objects, which most often determines the success of search operations. The higher the sensitivity indicators are set, the deeper the metal detector is able to detect the object. However, maximum values are not always good, as it increases the degree of influence of electrical interference and other foreign signals. Installation of such high parameters justifies itself only in cases of dry low grass and homogeneous soil, as well as in the absence of external stimuli. But such conditions are quite rare, often searches are carried out in heavily littered places where significant noise disturbances are created, so sensitivity has to be reduced, and as a result reduce the depth of detection.

There are general rules for adjusting sensitivity, the first of which is to assess the state of the soil on which the searches are made. For clean and homogeneous land, you can safely set maximum sensitivity, but in areas contaminated with metal debris it is better to put the average value, for example, on the metal detector Minelab X-Terra 305 such indicators - 7-8. The second factor influencing sensitivity is soil mineralization, which is the presence of minerals and salts in the ground. The greater their content in the ground, the higher the mineralization and the greater the effect of interference on the work of the metal detector. Therefore, to reduce interference, sensitivity must be reduced. The same goes for working near power lines, which make it difficult to find.

Why do we need metal detectors
The presence in the soil of a large amount of metal debris: corks, wires and other metal objects, make the metal detector ring almost incessantly. But if the treasure hunter considers this place promising, the search can be carried out, reducing sensitivity by 30-40%. In this case, not the least role is played by a metal detector coil, standard mono-coils of small size and “snipers” up to six inches are quite capable of coping with such tasks. High mineralization affects sea beaches, so setting 70% sensitivity value will also be relevant for search in shallow water. By the way, all these rules concern both inexpensive and more solid models of metal detectors.
