Graphic scale discriminator. The scale on the metal detector screen that displays which group belon

There are cheap (inexpensive) metal), metal is the average but price, and is expensive (professional). I have to say, the findings bring everything metal! Price metal detector does not affect the number of findings and not fully the quality but of the findings, the price of this metal detector find comfort and accuracy.
Comfort in search of a metal detector is the number of dug wells, which was not what you expected. A variety of additional but features, such as a fine tuning but (again affects the false signals that you took as a valuable discovery), the ability to lead a normal search on the beach (well, not all metal related to sea salt) backlight. What affects the price
With the rising price of metal, expect expansion of settings and options: Top division of finds (more accurate work discriminator) but Coil enlarged (increased depth and speed of search with the detector) More number of settings (search in automatic, and in fleece modes), more range of adjustment settings (fine tuning of various parameters by itself) Special Benefits (2 coils complete, in-depth profile of clipping debris impact or salt, etc.);
Discriminator, the most important part of the metal detector. He distinguishes between the metal and gives the opportunity but to receive feedback on specific findings. The parameters of the discriminator is a type of electronic but circuit, in which the frequency and accuracy, and a discriminator output information.
Type of electronic circuit globally divided into two categories. Analog signal processing (analog or floor) offers a very fast and sharp response to small finds, has an advantage in depth. But analog circuit metal detector is consistent clipping but metals. For example a search mask, which will review only of gold and silver (excluding intermediate between bronze and copper) can not.
Frequency of a metal detector has some peculiarities. Low frequencies but (below 5 kHz), designed but to search for great finds and less subject to external salinity. High frequency (5-9 kHz), universal and suitable for finding almost all purposes, from coins and jewelry findings but to BBB. High Frequency (9 kHz) is best suited for small size and findings include non-ferrous metals (monety. jewelry, native gold).
Audible feedback. Audio signal indicates that when the coil is the goal. In search of a metal detector, but the focus searcher concentrates more on the ground over which the moving coil without looking at the screen (if any) metal detector. Audio Review metal detector is one tone (usually in deep metal), but multiple colors (low iron sound high for findings of nonferrous metals) and many tones.
Graphic scale discriminator. The scale on the metal detector screen that displays which group belongs to aim at your metal detector coil. Metals on the graphical scale is almost always in the following order: black metal (extreme left segments of the scale), gold, bronze, copper, silver (rightmost segments). The more segments are on the scale of the discriminator, the more accurate you can determine before but finding its excavation.
VDI or Target ID. Numerical designations purpose. There are professional metal (eg Fisher F75), in which a small image scale but is VDI, which also allows us to estimate finding more accurate than just on the graphical timeline. Number corresponding to a particular group of metals. VDI Classic range is from 1 to 99. The first number to 30 correspond to black metal, then as far as "light." Latest (90) will show that the coil lies under your discovery of silver. Coil metal detector
The main property search coil, the coil over the more she sees discovery. But this is a clear advantage and hidden flaws. A large coil is less accurate mode pynpoynt (exact definition cents purpose). Great reel can often "hang" once in two or three goals in one sweep. More coil size, bigger and its weight (affects tired hands). For the main search coil is better to have 11 inches.
Other properties of the coil. Type Coil Mono and DD. Reel DD better suited for high-frequency metal detectors and search for coins. Coil Mono versatile and has a little more depth detection (plus better pynpoynt). Round coil and an ellipse. Circular coil has a small increase in search speed. In reel ellipse better pynpoynt and division are next targets. Both advantages in practice it is very difficult to notice each other. Plants and range adjustments
Cheap metal, often working on a "plug and went to look." Of course, this is a big plus for beginners. But the practice of searching with a metal detector, the understanding that if the metal detector properly compensates the influence of the soil, it is possible to obtain an increase of the depth of several centimeters. Or when finds another rod from the ground, and the sun is already sits in an expensive metal detectors can be used for backlighting. This additional Setup
