Radar Remote Metal Detector High Accuracy Frequency Synthetic Radar Remote Metal Detection System Item Type: Radar Remote Metal Detector Material: Aluminum alloy, ABS Battery: Lithium battery 2000mAh (built in) Use: Outdoor exploration, archaeology, treasure hunting Basic Parameters: Detection Distance Range: 1-1000m Detection Depth: 1-50m 1. Power On Step: Find a flat ground (even in the car compartment) to stabilize the instrument or put it on your back (the location of the instrument is marked as point A), turn on the main switch, and select the frequency of the desired substance through the gear and FM knob (we provide the frequency table for reference), turn on the far knob, and turn the close knob to the farthest, and the startup is complete. 2. Dual Joystick Use: This is the most basic and most important step, and it needs to practice repeatedly. Lightly hold the metal rod part of joystick with both hands (do not connect the weight detector first), stretch the telescopic antenna to the longest, keep the two antennas parallel to the ground and both point forward, and place the host on a position on the ground A. Do a circular motion around the host at a distance of about one meter from the host, relax your shoulders smoothly, and walk gently and slowly (very important! The speed of walking is greater than the speed of the double pole crossing, which will cause the detection to fail) Remember: People who operate with ease and peace of mind will operate more successfully than people who are nervous and rigid. The feet are slightly apart, the arms are close to the body but not too tight, when holding the receiving rod, the palms and wrists should not be too hard, so that it automatically reaches a state of balance in the hands, and always parallel to each other and to the ground, so that increase its sensitivity, or tilt it down slightly to achieve a better balance (if you are new to molecular frequency detection), if you find that the two rods cross, it means that there is an expected target reflecting back the signal, mark the point as Point B, connect AB as a line, pointing to the location of the expected substance, then move the launch host to another place C, repeat the above process and draw a line CD, then the intersection E of the line AB and the line CD is the location of the expected substance. 3. Use of The Weight Check Controller: If the material to be searched is very far away or the weight is small, the reflected signal is weak, the two rods cannot cross, and the E point cannot be located by the above method, then it is necessary to connect the weight check controller. Connect the bottom screw of the joystick antenna to the output jack of the weight detector with a special cable, turn the knob of the weight detector to the left to the minimum (at this time, the magnification of the signal is the largest), and then repeat 2 method. Move until point E is found. When the signal of the weight check controller is put to the maximum (the smallest or farther objects can be detected), a buzzer will sound when you touch the two poles. If the buzzer is small or inaudible, it indicates that the battery is exhausted and needs to be replaced Battery. 4. Single Joystick Use: The holding method is the same as the double joystick. If the expected target return signal is encountered, the single joystick will point to the direction of the expected target, and the E point can be found by using the two line crossing method. 5. Determination of Molecular Frequency of Any Substance: Two people are required to cooperate, one person turns on the power and slowly turns the frequency adjustment knob, the other person holds the double joystick with both hands at a distance of one meter from the host and points forward parallel to the ground (put the object under test on the ground under the hands), if the double sticks are crossed , indicating that the corresponding frequency value may be the molecular frequency of the test object, and then move the host in a direction, repeat the test, and finally determine the frequency or spectrum of the test object.
