Introduction                                                                                  

VR Long Range King Introduction: This model is our new upgraded version. VR MetalDetector System: The VR Ultrasonic Long Range King is an advanced Metal Detector System utilizing advanced FORWARD GAUSS technology that is both an audio and visual detector.

This metal detector was first used in the field in 1984 and the FORWARD GAUSS technology that it uses has proven to be (by far) the most successful.

This system was originally developed for professional archeologists and treasure hunters and has been used both on land and under water. With the development of faster and more complex processing units and a reduction in the cost of materials, we were able to begin offering this breakthrough technology to the general public at a much more affordable cost. Part of the success of this metal detector system is that it does not look like a standard metal detector. Instead, it has the appearance of a fine, well manufactured piece of scientific equipment that one might expect to find at an archeological site.

 
The VR Long Range King is custom built in a sturdy, hard side, padded case with two locks. The transmitter is case mounted and includes the Standard Six elements with selector switch. The system includes an installed, rechargeable gel cell battery with charger, transmitting antenna, receiving rods and receiver with belt clip, headphones and user manual all inserted into the specially fitted case.

2. Most common frequencies are Rock Gold, Sand Gold, Silver, Bronze, Brass, and Precious Stone.
3. Detecting Range: 100-1500m
4. Detecting Depth: 5-80m
5. After tracking target, you will have some idea of the identification and the exact pinpoint.
6. The face (front) of the transmitter has six LEDs (channel indicator lights) across the top; each is labeled for a particular element.

Traditionalmetal detectors rely on arm waving, a days work is very limited. If a bad terrainovergrown with weeds is unable to work.Dueto the different principle,the probing depth of traditional meta detectors arevery limited. The metal detector to find a better way, I have to introduceforeign advanced technologies in the long-range detection ofmetal,afterrepeated testing. VR series developed grest depth, distance metal detectionsystem that is kind of precious metals direction indicator. Ultra Deep largeares characterizes by rapid scanning detection. Minutes long metal detectors todetect the size of an or dinary workload. Its signals can penetrate themountains, figure out what gold / silver / copper three metals. The instrumentis microprocessor controlled,the central unit,including abnormal correction,multi-shift programming prior to the separtion of transmission and switching.Together in the great scope of sending and receiving signals objects, thebiggest measuring range of up to 500 meters. According to Hill 90 meterspenetration test signal attenuation not, address the conditions in the idealsituation, The detection of a single acupuncture needle up to several metersdeep. Simple equipment, not education could learn in one day. Itshould be noted that the survey team is a rigorous process of scientificdiscovery of the instrument, the familiar is very necessary. Meanwhiledetection is difficult. Lucky with patience,you have great success. Some of thefollowing suggestions may help you use the right equipment: Move the equipment and accessories storein a cool dry place.  Cell phone, pager and other electronicequipment in use. Please do not use machines.  In bad weather, such sa high wings danlightning, Please do not use the machine.  The high temperature in the weather, notthe instrument under the sun 47s ,They poured sand apparatus should try toavoid such foreign bodies.  Avoid wet equipment. 

Equipment by preventing excessivevibration.  Should always check battery consumption.  Harder rock in the ground or in theground, it is necessary to use tools to prevent damage antenna.  Practical experience in the grasp ofdetecting helpful.  Do not attempt to open the adjustmentapparatus,equipment repla cement parts without exertion.

How difficult to reach the region through the use of the object measured triangle rules trianglar object to the location, to direct attention to one location and direction. From a position of the left or shifted to the right, continu ally testing the location of the object, until the launch of the signal produced by the first line and angle 45degrees just as the signal line. The distance between the first position and the position is exactly the distancr between the object and a place.
