Most metal detectors have similar characteristics and are about the same the depth of search (table. 3.1):
- 20-25 cm for small-sized object of type Soviet nickle;
- 80-100 cm - large target.
They are a typical "monetti" that is just designed for search small value items, such as coins and jewelry.
Table 3.1. Comparison of metal detectors for beginners
There are pleasant exceptions, but they are characterized, as a rule, large size search coils (such as AKA, MD and Minelab'a), which defines them greater versatility.
It is worth noting some of the most attractive models that are "distracting" from the total number, and well-known devices:
- First is the Minelab Musketeer Advantage due to the good design of the coil.
- Secondly, it's AKA "Junior", is attractive because its functionality competes with foreign metal detectors costing much more.
- Thirdly, Garrett ACE 250 at the expense of ease of use and excellent the ratio price/quality/functionality.
- Fourthly - White's Prizm II and White' s Prizrn III, which, although more expensive, but the depth of work they have a little more (2-5 cm for small finds with coils in standard trim).
- Fifthly - Tesoro Silver uMax is characterized by its good ergonomics.
- Sixthly - MD 5008 DTS due to the low cost with a larger coil, well suitable for search medium and large metallic (iron) objects great depth without purchasing a dedicated device.
The entry level detectors of the Russian production
The metal detector RM (Resonant detector) and ECD detector (Resonant detector with discrimination) is a simple device with a small search depth. The difference between these devices from each other the name implies, it consists in functions discrimination, i.e. the ability to respond to certain types of objects, for example, only for non-ferrous metals, and ignore the others.
Both devices there is no static search (in static mode audible indication device is triggered regardless of whether the coil over a metal object or not. The main mode of the search is a live search. The essence of dynamic mode is that the detector detects objects only when driving the sensor device.
Consider owned switches
The RM has a single knob power/sensitivity", RMD added switch All metal/ non-ferrous metal and regulator of the level of discrimination.
The cost of these devices is approximately $150 and $250, respectively.
Metal detectors medium level for beginners Russian production
AKA 7245 "Junior" is one of the most popular models among novice search engines, which can be attributed to a higher class.
He has an excellent depth of search, function high quality manual compensation the influence of soil (or balancing). The essence of this important function is to reduce the impact ground mineralization. Without properly conducted balancing the metal detector does not ensure optimal search depth and accurate identification of the type of the object.
Some devices are capable of:
- or automatically adjusted under the conditions of the soil;
- or are initially set to its kind of average type.
Among the important adjustments and modes, it should be noted:
- the presence of the gain knobs and the sound threshold (minimum signal level from the target at which the detector indicates its presence);
- different modes of discrimination;
- dynamic and static search mode;
- the three-tone sound indicator on different types of objects.
Stop for an audible indication more:
- a low tone indicates the detection of small ferromagnetic objects (nails, wire, splinters, etc.);
- mid tone alerts you to the presence under the sensor device folkeoplysning items;
- a high tone indicates the detection of objects of non-ferrous metals or large sheet-like objects from iron.
The disadvantages of this device are: large weight of the device; specific weight "coil - e-block - battery", which requires some getting used to.
The cost of this detector is about $400.
Metal detectors medium level of Chinese production
The metal detector MD-3010 is designed to detect ferrous, non-ferrous metals, located in the ground at shallow depths.
Identification of the detected target is indicated on the display by the icon. The display has 8 sections visualization of detected objects: nails, corks, coins, gold, ring etc the Device duplicates the target is detected by one of 8 beeps. It should be remembered that, as a rule, the icon on the display has nothing to do with a real find, and is used as a benchmark for similar size objects.
LCD display section has a pointer to the depth of the detected target. The device automatically adjusts the ground balance. Enhanced features discrimination (exclusion) unwanted objects.
The existence of discrimination is typical for devices with digital processing. Adjustable sensitivity and volume of the internal speaker.
Price - $300.
The difference between analog metal detectors MD 5006 and 5008 DTS is:
- the 5008 DTS there is a remote battery pack (for belt), which is essentially increases the battery life;
- the 5008 DTS have additional coil of larger diameter, allowing to make a deep search (the manufacturer claims up to 3.5 m large items).
It should be said that in mode deep search coil like this larger diameter) worsens the discrimination of metals. This is typical of so called deep metal detectors (as well as when using coils large diameter "nepovinnyh" devices).
- Otherwise, they are identical, each available:
- switch, modes responsible for the discrimination/detuning from the influence of the soil;
- potentiometers setting the audio threshold, ground balance, discrimination and sensitivity (gain);
- dial indicator with areas for non-ferrous and ferrous metals.
Sound indicator - single.
Price - $300 - $400.
Metal detectors average production USA
Series detectors ACE company Garrett uses microprocessor technology the same as more complex models, but with some simplifications. It affect the time of "adaptation" and the ease of setup.
Garrett ACE 150 is the simplest model in the range. It is equipped with:
- graphical identifier of the detected object, divided into 5 segments;
- the three-tone audible indication (low sound in iron, higher - on objects from non-ferrous metals and "call bell" signals the presence of "cointype" goal);
- indicator depth;
- three modes of discrimination;
- press to change the sensitivity (4 segments).
The ACE 250 metal detector, unlike ACE 150, equipped with accurate mode target detection (or static pinpoint mode). Also increased the number segments of the graphic scale (up to 12), sensitivity (8), more precisely determined depth, the number of modes is increased to 5 with the ability to quickly create their own mask.
Both devices (ACE 150 and ACE 250) can be equipped with additional sensors (coils) increased size. This makes them more versatile (for example, with a coil of small diameter makes it easy to search heavily littered with iron. Indeed, in this case, "different" closely spaced targets, for example, an iron nail and a coin, and larger - good for searching for a greater depth).
ACE 250 is one of the most popular models in the environment beginner searchers thanks to the excellent ratio price/quality.
The price is approximately $200 - $300 for ACE 150 and ACE 250, respectively.
Consider products other North American company, Tesoro Electronics, Inc.
In General, the firm Tesoro Electronics, Inc produces a very light-weight device (discussed below models weigh about 1 kg) and with a lifetime warranty.
To budget models Tesoro can be safely attributed Compadre and Siver µmax.
Compadre is designed on the principle of "less is better". It only works in dynamic mode and automatically rebuilt from the ground. Has the only regulator of the level of discrimination/switch with a wide range settings.
The cost is $300.
Silver µmax uses microprocessor technology, has three bodies management:
- three-position mode switch all metal/discrimination/test battery";
- the regulator of the level of discrimination;
- the sensitivity control dial/switch.
Also used a larger diameter coil (using other, interchangeable coils impossible). This detector is quite appreciated users.
The cost is $300 - $400.
Consider a few devices from Fisher.
Metal detector Fisher 1212-X is the most simple device in the product line of the company. It has a single control - the level control discrimination/switch engaged full-range discrimination - from response to all metals to the maximum level. The non-replaceable coil, static mode is missing.
The cost is $400.
Metal detector Fisher 1225-X better. It is already present static mode of detection, sensitivity and test batteries, and also the ability to use multiple search items.
The cost is $500.
Now consider metal detectors North American firms Bounty Hunter.
The Bounty Hunter metal detectors have long been widely distributed and discussed on forums. When looking at the design of these devices does not leave the feeling of "igrushechno", many users complain about the fragility of the structure. But at stated characteristics they honestly fulfill the money invested in them.
Among those present on our market models from this category, you can select some of the most popular:
- VLF is the simplest instrument employed in the dynamic mode with regulators discrimination and sensitivity and is equipped with a needle indicator. The cost $250.
- Tracker II - provides automatic and manual ground balance, has three schemes of discrimination and two-tone audible indication. The cost $200.
- Tracker IV is a simple to learn and use dynamic detector standard for Bounty Hunter design. Has two schemes of discrimination, one of which is always turned on and the other turns on when the operational check the detected object (frequency discrimination). Ground balancing -- automatic without loss of sensitivity. Pointer purpose analyzer allows to obtain conditional information about the detected metal object in depending on its conductivity. Adjustable audio threshold and the tone signal (sensitivity). The cost $250.
- Quick Silver - a fully digital instrument with three patterns of discrimination, automatic ground balance with no loss of sensitivity, LCD display 4 band digital ID that allows you to get information about likely discovered a metal object and a three-tone indication. The cost is $250.
- Quick Silver Lone Star is a modern metal detector, has a 6 band digital identifier (coins, gold, nails, trash, etc.) and digital display modes. The other parameters - like the previous models. The cost is$350.
- Quick Draw II - has 5 modes of discrimination and digital ID the extended range. But, unfortunately, the static mode is missing. The cost is $400.
- Sharp Shooter II is the most perfect in the public sector. In addition to extended compared to previous models the main functions (6 circuits discrimination, measurement depth, nine - segment ID goals) finally, the static search. Cost - $500.
Unfortunately, all devices, despite the significant functional differences, have approximately the same sensitivity (approximately 20-25 cm small coin).
The entry level detectors made in Australia
Metal detector Minelab Musketeer Advantage specifically designed to search coins, treasure in abandoned buildings, basements and attics, lost jewelry on the beach. It is distinguished by its reliability, ruggedness, and easy operation, equipped with many necessary functions.
Configurable sensitivity, manual and automatic tuning the ground controller is present discrimination and the function of the exact location target (pinpoint).
Musketeer can be equipped with 10 or 8-inch search coils DoubleD, which have a wider coverage area compared to conventional concentric sensors.
Coil DoubleD proved to be only malozamechennyj sites, as when such technology worse are separated by closely spaced objects due to the wider beam.
The cost of this device to $350.
Metal detectors primary and secondary level from UK
Line of microprocessor-based detectors Prizm company White's Electronics actually covers the category of devices at primary and secondary level. Consider for example the model Prizm Prizm II and III.
Display settings and type of the detected object is performed on the LCD. All search objects divided into 8 types are marked cursor. When you configure discrimination can consistently deny the reaction to objects the first five categories, starting with iron.
Devices can work both in dynamic and in the mode of accurate detection in which you can search. There is a sensitivity adjustment. In addition to adding to the model Prizm III indicator is present the depth of object.
The cost of the Prizm II is $400, a Prizm III-$450.
Metal detectors C. Scope CS220/330 in addition to a fairly original design ("ergonomic", according to the manufacturer) and lowest rates (less than $350.) can boast of sensitivity and discriminator, and 330-I setup button/trim iron. Static mode is missing. Coil cannot be replaced.
The CS660 metal detectors, CS1 M, CS2 MP is almost identical to previous models, but in the more usual cases. Differences - the larger diameter coils (20, 20 and 25 cm, respectively). There is a switch/controller sensitivity discrimination, the model CS660 has a reset button configuration (reconfiguration), CS2 MP - mode maximum deep search when you install discriminator "All metals". The cost CS660 - $300, CS1 M - $350, CS1 M - $400, respectively.
