Handheld metal detectors are designed to detect metal objects carried by people or objects. It can detect metal objects within people`s carrying parcels, luggage, letters, fabrics and other metal objects. The special appearance of its sensitive surface makes it easy to operate. Better than ring sensor type hand probe. Ultra-high sensitivity, special applications. Such as prisons, chip factories, archaeological research, hospitals, airports and so on. Today we come to understand the hand-held metal detector troubleshooting methods:
Phenomenon seven:
Symptom: the sensitivity of each model to adjust the location of the hole and how to adjust the sensitivity.
Cause Analysis:
1, the adjustment hole in the back of the detector on the back of the battery cover, a small hole in the small screws;
2, all: clockwise to improve the sensitivity, counterclockwise to reduce the sensitivity.
3, only need to use a micro screwdriver to adjust it, the rest of detectors can be adjusted by hand in the external.
With Hobby Metal Detector you can hunt for coins, relics, jewelry, gold, and silver anywhere. The Underground Metal Detector is easy for people to operate.The detector works at Very Low Frequency (VLF), 6.6 KHz , which is designed for accurate detection. its definitely can mees customs requirements and you hobby.The detector would only respond to metal objects but not the effects of iron ground mineralization at very low frequency.The detector distinguish metal objects between different types of ferrous (iron and steel) and non-ferrous metals (gold and silver) by different discriminating circuitries. The detected objects are shown on the LCD display. You can decide immediately if the objects worth to be recovered.You can set the detector not to respond to some objects.
