Product Description

It is an instrument to locate gold, silver, copper, diamond in large distances. High penetration depths are also possible with Original American Microprocessor. This category presents our long range detectors, which are specifically tuned into identifying precious metals and gem stones at great distances. This compact equipment offers maximal performances.
Thank You for your interest in GR Detector.

Function introduction

1.Threshold

1) Threshold has the function of adjusting the alarm sound and laser, 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 button.

2. Sensitivity:

1) The key is double function key, it is not only a power switch but also is sensitivity button Turn toward the direction for the power supply is turned OFF and the sensitivity-reducing direction, towards ON direction to toggle the power on and the sensitivity increasing direction.
2) It is OK as long as the first light is on when adjusting this function key, if this function key is adjusted too large or too small, which will reduce the accuracy of detection.
3) Hear the crisp clicking sound when the function key to toggle OFF direction, do not continue to set aside, because the switch has been in the end, continue to insist on the force dial, the instrument will cause damage.

3. Laser:

1) The main function of the laser is to assist the user to provide a clear visual indication of the direction in the search for treasures, in the absence of alarm, the laser instrument is not emitted the laser, its normal operation is synchronized with the audio alarm, that is to say, in the process of your search the treasure, if hear the alarm beeping from headphones, you timely need to see the direction of the laser ray indicated, you need to do force on search following this direction, and make with an arrow mark direction indicated by laser, then continue to search in another location, viewed the direction indicated by the laser rays when the same alarm happen again and marked with an arrow。In order to improve the accuracy, you need to repeatedly gather several test points, then observe the crossing point, if the intersection is away, It represents that the treasures is away from our test points, if the intersection is close to the test point, the treasure is in this position of intersection. Congratulations, you win the lottery.
