ОСНОВНАЯ ОПЕРАЦИЯ

MD-810 is used for outdoors. There are too many objects indoors, and all kinds of electrical equipment that will bring interference signals. So it is not fit for using the detector indoors. Field detection is more complicated, the composition of the regional soil, the component, size, shape and the oxidation degree of the underground metals will all affect the detection results. This chapter is only the general steps of field detection. You should operate again and again, and accumulate experience to achieve good results.

1. включать
   Hold the detector, keep the search coil be away from the ground. Press the Power button, the detector will sound two moo tones, and all the LCD patterns are lighted for a while. And the detector is restored to the setting of last time.
2. Установите режим работы
   In general, the user could choose the ALL METAL mode. At this time, the detector will respond to all kinds of metals.
3. Choose the sensitivity
   The user always expects to set the sensitivity higher. However, in the higher sensitivity range, the detector will be more sensitive to the electromagnetic interference that comes from the power lines or cables around, and it will react abnormally to the mineralization soil or electrical conductivity soil. If you move the search coil in the detection area, and the detector sends an unstable false signal, please decrease the sensitivity. If you operate the detector with your partner at the same time, please pay attention to keep more than 10 meters away from each other, and decrease the sensitivity appropriately.
4. Move the search coil
   When detecting, move the search coil at a constant speed, not unsteadily. Let the search coil be parallel with and about 1/2 inch from the surface, not to swing it like a pendulum high and low above the ground. (See Fig 18) Fig.18Most of the valuable metal objects will send repeatable signals. If the signal isn’t repeatable, it’s mostly a false signal. When there is a clear sound instructing the buried targets. You could read out the approximate target type and depth on the LCD screen. And you could also move the search coil above the target objects fast, in order to get a more stable signal.
5. Make use of the sound, to help against discrimination
   In the process of detection, you needn’t always watch the screen. And the sound identification system will sound three frequency tones to help discriminate the targets.
   Low pitch– 5￠nickel coin and so on.
   Meddle pitch– pull-tab, soda bottle and zinc coin.
   High pitch– copper, aluminum and silver metal, such as 1￠, 10￠, 25￠and so on.
6. Make use of the digital cursor, to help discrimination
   The following table is used as a preliminary guide. The approximate ranges of US dollar and pound sterling coins are listed in the table. When detecting, there may be some changes in the number, depending on the composition, size, shape, distance from the search coil and speed of scanning. The surrounding soil also affects the numerical value. There are differences in casting coins in different years. The values in the table are the only reference, Gold has a wide numerical range, a thin ring is about 45, and a rough ring and gold coin may up to 70-80.
7. Depth indication
   The depth indication is accurate for coin-sized objects. Large objects or irregularly-shaped objects will yield less reliable depth readings. If sweeping at the same place for several times, but shows the same depth, and it is the more accurate detection. If the depth indication varies, try to change the angle of sweep. There may be more than one target present.
8. PINPOINT
   When detecting in the motion mode, as you should persistently move the search coil, so although you find the region that burying metals, it’s not easy for you to determine the exact location, it gets the digging difficult. At this time, you should recur to the PINPOINT mode.
   1. Press the PINPOINT button, the PINPOINT cursor is lighted, the depth cursor will be full scale, and the detector will sound a low single-frequency tone, the sensitivity is in the highest state.
   2. Let the search coil approach the ground, move the search coil slowly in the region, where you find the target. In the position where the single frequency tone turns louder, and the signal strength cursor begins to appear, Continue moving the search coil slowly until the sound turns louder, the signal strength cursor is full scale, and the depth cursor is the lowest. Now, you have locked the target location roughly.
   3. If the area with the strongest signal is larger and the location is not accurate enough, you can keep the location of the search coil unchangeable and exit the PP mode. Then press the PP button again and repeat the above operation. Until you move the search coil slightly, the strongest signal will be smaller. Now, the position of the metal target has been locked. You can mark on the ground by the center of the open search coil, to facilitate the digging.
9. You can choose another operation mode according to your needs and experience.
   If there are more scrap metals in the detection area, you can choose the DISC mode to eliminate the metals that do not need to be detected. Remind you once again, when detecting in the wild, due to the impact of the ground condition, the discrimination indication and depth indication will be all deviations. The composition, size, and oxidation of the metals will all affect the indication result. It’s necessary for you to consider these factors before choosing to eliminate a certain metal or determining whether there are precious metals. Not to eliminate the precious metals.

In fact, the sensitivity in the non-motion mode is high, searching metals directly using the non-motion mode is also a choice. In some regions. the ground is too narrow to sweep the search coil, you could choose the PINPOINT mode. In the severe mineralization or salinization region, you could try to sweep using PINPOINT directly.

ВНИМАНИЕ!

1. In areas with heavy traffic, please do not wear earphones, in case an accident occurs.
2. Always obtain permission before searching any site.
3. Keep away from the region that may bury the electrical line, cable line or pipeline, in particular, the pipes that are full of flammable gases and liquids.
4. Do not detect in the military area where may bury bombs or gas explosives.
5. When excavating the target, use the reasonable method, not destroy the vegetation. Leave the land and vegetation as it was, fill in the holes after the excavation.

РУКОВОДСТВО ПО УСТРАНЕНИЮ НЕПОЛАДОК

Use with headphones
The MD-810 is equipped with a 3.5mm headphone jack. Using headphones extends battery life, and also prevents the sounds from bothering bystanders. It also allows you to hear subtle changes in the sound more clearly, particularly if searching in a noisy location. Gold nuggets are often very small, so closely monitoring changes in sound using headphones will improve your gold prospecting results.
