The choice of a metal detector is a responsible task, but it is better to give preference to a used device. Thus, you can find good options for little money, but you should be careful, you should carefully check the device before buying it.
Where to go
It is good if in your city there is a store specializing in the sale of used metal detectors, which are presented in a fairly large assortment. Often a store guarantee is given for this product.
When such a store is not possible to find, the best option would be to turn to an experienced metal detector, who should be looked for through acquaintances. Perhaps he himself will offer you this unit or tell you who to contact for this purpose. Such people will not deceive, they will teach some of the subtleties and secrets of their craft.
The nuances of buying
It is best if you are in the same city with the seller, so that you can test the metal detector in action before buying. If you are offered to send the metal detector by mail, then it is better to refuse, since possible breakdowns can be easily attributed to the negligence of postal delivery. Moreover, do not send an advance payment, you risk not getting anything at all.
What models of metal detectors exist
Models costing from 10 thousand rubles are more suitable for entertainment. If you like to travel outside the city to nature a couple of times, then this option will be the best choice for your hobby. Such models have a detection level of up to 1 meter in depth. This is quite a good discriminator that does not pay attention to small metal objects that are not of particular interest. Such metal detectors are more suitable for finding scrap metal.
From such models, it is better to choose those that have a detection depth of just over one meter, while having a high-level discriminator. In addition, you can pay attention to such additional functions as tuning to the ground, polyphony, tone background and tuning from electrical noise.
The most acceptable choice, of course, falls on a model costing over 20 thousand rubles. Perhaps these are more serious metal detectors often used by professionals. There is already a much deeper depth of detection than the cheaper models. This is a great option for finding small coins, treasures, and other small gold nuggets. If you select a coil with high sensitivity for such metal detectors, you can significantly increase the detection depth, at least by 30%.
More professional metal detectors usually cost more than 35 thousand rubles. These are no longer just analog models, but processor-controlled multi-frequency units capable of detecting even the smallest metal objects at a depth of two meters. Such models can determine the type of metal, its size and inductance.
When choosing, you should pay attention to those models whose target detection frequency reaches up to 28.
Checking the main nodes
The most necessary element of a metal detector is a coil. Age is important for her, because, provided that it is used correctly, this device can work properly for more than five years. Do not use a cracked coil, as it will most likely give implausible information. Then inspect the strength of its attachment, whether the barbell is native to her and, in general, whether it is working properly.
Be sure to inspect the microcircuits and the processor, check the operation of the buttons, the display for corrosion or moisture. Pay close attention to the power supplies and their connectors. Test for false signals.
