Multifunctional Digital Metal Detector Treasure Hunting Gold Silver Handheld

PU500 underground metal detectors novel, small, portable, high-performance, practical professional metal detector. Built-in automatic balancing system, easy to use.

PU500 underground metal detector is mainly used to detect and identify hidden metal objects buried in the ground, in addition to its military use, can also be applied:

1. Customs inspection and safety check;

2. Detection search of Interpol department ;

3. Detection of raw materials, fuel, food metal;

4. Exploration of underground pipes, lines;

5. Archeology, prospecting;

6.Discovery of gold and silver treasures buried in the ground and metal artifacts;

7. Acquisition of scrap metal.

PU500 in making old-fashioned metal detector, the most annoying problem is the impact of the ground: With the change in distance between the probe and ground equipment changes also followed the signal, if the probe swept uneven ground, the change is even more big, the operator seemed everywhere to hear the sound signal, figure out where the real metal buried. This phenomenon is called "mineralization reaction." Cause "mineralization reaction" reasons, is due to a variety of soils and minerals constitute the instrument sends a signal to the soil structure in complex place, "mineralization reaction" very strong signal that it caused even bigger than the metal signal, which when it is difficult to determine where the operator is signaled in the end is buried metal or "mineralization reaction." PU500 instrument features a balanced line, can eliminate the influence of all the "mineralization reaction", signaled only when the probe encountered metal, thus greatly improving the probing depth and accuracy.

Product Features

PU500 has two operating modes: This product has an all-metal and identify two modes of operation. All-metal mode which is the effect of all metals have induced pattern recognition patterns to exclude black metal pattern. Press the Mode switch. After this time for the all-metal mode, detect metal, you can push down the Mode switch, this time to identify patterns that can be used to determine whether the non-ferrous metals.

Metal Detector: can detect metal and identify the type of metal.

Note: If the battery is low to not use the instrument (LCD screen display LOWBATT) the need to replace batteries

Warning: You must ensure that the batteries in the correct direction, otherwise the instrument will bring irreparable damage.

PU500 underground metal detector with an audible alarm and instrumentation, with probing depth exploration area is metal, shape, weight, have a great relationship, in general, the larger the area, the greater the number, the greater the corresponding probing depth ; on the contrary, the smaller the area, the fewer the number, the smaller the corresponding depth. According to local soil depths environment and the type of metal the size of the probe different depths are different.

PU500 Instructions:


ABCD four knobs to adjust: boot, do not set the knob B is high, the 9 o'clock position on it. In the absence of metal instruments will be filed vacant ground, the instrument and the ground distance of more than one meter, then press and hold the button RST, and remain intact. Left rotary knob B until you hear the speaker alarm sound. A point and then rotate the knob to the right position, and then release the button to reset RST. The instrument samples metal 20-60 cm distance, you'll hear the same siren. If the sound is high, lowering the knob counter-clockwise A sound; if the sound is too low, clockwise A knob to adjust to the appropriate voice for emphasis. Note: A knob after each adjustment, need to press the RST button until you hear the same siren. When searching in highly mineralized zone, B knob to set lower, instruments and from the ground to be higher, and in normal use, the right hand straight to mention live instruments, slow-moving can be. If the instrument finds any metal objects, you will hear an alarm sound and there will be some display on the LCD screen. If you hear a siren and a different sound, press the RST button again, and you'll hear the same sound. Repeat the operation started, until you adjust to the appropriate sound.
