detecting from long distances .So we decided to find the most useful detectors that is really
help Prospectors in searching.
First of all , let us say that we are writing to you as a treasures hunter with many years field
experiences using traditional metal detectors. The following statements and opinions are our
own, and we aren't connected with any company except our dealers which you can find
them in our dealers page.
Last months we began using a GR detector devices and have been working with it . GR
detectors are tools that is supposed to detect gold and silver and any other kind of metals
and gems from long distances. Our detectors are using special easy method in searching by
holding the device as you would a pistol and sweeping it right to left and left to right in front of
you , and if there is any target , you will see the device sensing target exact place.
Correct balance in using the device is a very important thing in searching . By using carefully
the methods in the user manual you will be very near to the target area within a few square
feet then you can use your traditional metal detector above the target and that is the final
step in your search.
The most common question from prospectors are, does it really work ? The answer to this
question is yes. We believe that is the device working correctly . However, the degree to
which it works is determined by the skills of the prospector and certain other factors. For
example, balancing with the device while sweeping and walking with it can take some time to
accomplish. So you must learning carefully how to use detectors.
Fortunately there are video now available on balancing and tuning the scope. These videos
provide detailed instructions about using the device ,which we provide it to anyone trying to
learn how to use the device.
The most important steps in your search and that reach you to the target it self are：First you
most using the devices carefully and try to use them many times.Second you most reading
devices user manual carefully.Finally watching some useful videos will be very good for your
learning.
Through GR international detectors you will save more time and money, because you will
working with the most technical devices in the world.
In addition to good practice will increase your skills and will helping you to find your goal
easily.
In conclusion, we opened our branch in China to facilitate the process of dealing with our
customers from Asia and Africa.
GOOD HUNTING!
A lot of time is needed to search on large areas with regular coil detectors,because the
whole area must be searched inch by inch due to the nature of these detectors, that they
only give a signal while they pass over the target.With GR-100 Long Range Detectors,you
will be able to search a large area in a very short time which will decrease your searching
time at a significant point.

FUNCTION INTRODUCTION
1.Threshold
1) Threshold has the function of adjusting the alarm sound and lase, that is to say, the less
the threshold, the greater the detection range, even very distant object can be detected, but
the error will be relatively bigger, the best way is to combine multiple identities for summary
judgment . I f the threshold is adjusted larger, the stability will be better, but there are some
small volumes of treasures will be filtered out .This function requires a personal experience
and local mineralization value to adjust. If the person is familiar with operating this
instrument, it will be very easy to set a reasonable threshold.
2) Threshold is set clockwise, the smaller if the more transfer, but if the threshold is set
counterclockwise, the greater if the more transfer, we can adjust the threshold until it can not
be move. Please don’t adjust the threshold any more if the threshold can not be move.
3) Threshold is a key function button, you can adjust it following left and right rotation,
stopping press and pull this this button.
