What is portable equipment for the search for metals in the ground, the “Minoist” is called in the common people, and the most common model among them is Garrett 250. Its professional adjustment of sensitivity, low weight and convenience are recognized by many users. Coil for Garrett 250 (a device that accepts and transmits the user a magnetic radiation signal) is an integral part of the device as a whole and there are more effective types that is more effective work when searching for certain items.
The main types of coils
The standard set of the Garrett 250 device includes a branded coil from the manufacturer, which has quite good technical characteristics. But the release of additional components that can increase or improve certain parameters will always attract the attention of enthusiastic lovers and professionals. The main parameters of the differences in various coils are as follows:
- Mono-Rasis-have a fairly small capture diameter (depending on the size of the equipment) of the test area, which decreases relative to the depth.
- Coils made using DD technology are equipped with a wider seizure that allows you to increase the area of a single-mop search to 60%, but the signal weakening is already manifested at a depth of 20-25 cm.
- A deep -legged coil of the DD - has a fairly high speed of soil processing at large depths and the ability to separate those lying objects among themselves.
Increased size dimensions of the coil do not always give good search results, especially when it comes to small coins or jewelry, but it consumes more electricity and quickly discharges the battery.
According to professional seekers, optimally high results can be achieved, having at least two different types of coils in the kit and using them depending on the search conditions or soil condition. You can purchase the necessary options in specialized stores or order via the Internet.
