High-Precision Long-Range Underground Metal Detector Gr100

GR100 display parameters:
Detection type: copper, silver, gold, diamond
Search range: up to 1200 meters
Detection depth: up to 50 meters
Charger: 12.6V 1A 50/60Hz
Transmitting frequency: 5.6-6kHz

Specific functions:

It can determine the buried location of objects by connecting fixed points. If it is used with the underground metal detector md5008, or the more efficient XP underground treasure hunter, it can accurately locate the hidden place or location of metal.

Specific operation:

After receiving the machine, you need to charge the machine first. Both the transmitter box and the receiver need to be charged (because the built-in batteries of the transmitter box and the receiver are discharged during transportation, which consumes a lot of power). If you do not charge it, the transmission and reception signals may be weakened due to insufficient power, causing the machine to be unusable. The normal charging time is 5-8 hours. Now a high-current charger is used, which can be quickly fully charged. When charging, as long as the charger shows a green light, it is roughly full; continue to charge, it will charge slowly, and the longest charging time is no more than 12 hours.

Operation focus, point positioning:

After fully charged, we can operate the GR100 display screen. Take scanning gold as an example. Turn on the power switch of the transmitter box and the receiver. At this time, the power light on the receiver will light up. At the same time, we press the gold button on the transmitter box, and we will find that the corresponding gold indicator light on the receiver will light up; at this time, we need to use the pointer of the receiver to receive iron metal for about 10 seconds. The purpose of this is to eliminate the magnetism of the receiver. In winter, when operating, the pointer of the receiver needs to be grounded for 1-3 minutes to eliminate static electricity. Then, we take off the mobile phone and necklace that can send signals and put them aside; this is to eliminate the interference of metal on the body to the receiver. After that, we hang the transmitter box around the waist and hold the receiver in our hands. When holding the receiver, we must keep the receiver balanced to ensure that the receiver will not rotate because we are not balanced. After ensuring that the receiver is balanced, we can start scanning at a uniform speed in a certain direction. During the scanning process, we still need to keep the receiver balanced and pay attention to the indication of the receiver pointer. When the receiver pointer receives the signal sent by the underground gold, the pointer will start to rotate in the direction of the gold signal. If the gold is too small, the pointer may show a slight rotation or even no rotation. If it rotates and the rotation amplitude is large, we can roughly determine the direction of the gold, which is the direction pointed by the pointer. This also requires 2-3 confirmations. This point is confirmed.
