the ground will not change the critical sound, only in the face of the metal target , the
signal will send out.
6. When using the RECOG mode, the instrument may appear difficult to adjust or
sustained chaos alarm . Under normal circumstances we should adjust the GBAL
knob to correct the interference mineralization reaction .
Mineral Prospecting
With SLKD-M802 type instrument can detect buried mineral deposits which not very
deep, including natural gold bullion, pulse gold deposit sand deposit, and so on all
kinds of high-grade ore .
Detection of natural gold nuggets like finding metal coins as ground balance approach
to proceed. Most nuggets buried in the high degree of mineralization of formation , so
well balanced must be adjusted carefully in advance.
GOLD in the sand , as well as gold in the form of fine pieces mixed with sand
together, and there is often a large amount of heavy metals in sediment deposits, the
same signal caused by the mixture of black metal , but the reaction is weaker than the
pure metal , and generally sounding relatively wide area .
SLKD-M802 can be conducted screening of ore block. When performing this work,
the operator does not need to hand-held detector but the instrument is fixed in a
non-metallic support, tune out the critical sound, then make the pieces of ore close to
probe, according to the size of the sound to determine the high or low levels of
content. It should be remembered : After each test of a sample to press and release the
reset button. Determination of the metal content screening technology vein gold
deposits and the determination of the end of the old mine left mine wells is useful,
some ore mining people see gold at the surface of the leaves, the rest of the ore throw.
In fact, it is thrown away in some nuggets of gold still contained inside.
Detection Example
The description above of the mode of instrument operation, the operator can use the
instrument according to the specific circumstances.
Case 1
In an old house in search of deeply buried relics, for a long time due to the wide
variety of discarded metal debris such as nails, wire, old locks, pots and other debris
buried underground, these things are generally buried in shallow, the larger signal will
be issued, in order to exclude the debris away to detect buried deep targets. In this
