Chinese gold detector, Tianxun. I'd like to know something on this TX850 G2 machine. (2024)

FAQs

How deep is the TX 850 metal detector? ›

TX-850 Professional Metal Detector 2.5m Underground Depth Scanner Finder Gold Detector Treasure Hunter Detecting Pinpointer.

Gold is typically detected at a range of frequencies on a metal detector, depending on the specific model and settings. It is commonly detected in the range of 18 kHz to 71 kHz, although some detectors can go higher or lower.

Gold detectors are not a new technology, but many people have been using metal detectors to detect gold for ages. Over-the-years the metal detectors have become more advanced and provide you with the opportunity to find gold and many other metals. The world's best gold detectors can sense gold as deep as 40m-60m.

Most metal detectors can detect coins at an average maximum depth of 10 to 16 inches. Metal detectors transmit radio frequency signals from the search coil to locate the targets from the ground's surface to a depth of over 20 feet for large deep treasures.

A VLF, or “Very Low Frequency,” metal detector is (despite the name and what we know about frequencies from above) quite suitable for metal detecting for gold, though some will prefer PI, or “Pulse Induction,” metal detectors for gold.

Metal detectors work by generating an electromagnetic field, which induces eddy currents in nearby conductive materials like metals. Gold and silver are both highly conductive metals, so they will generate a strong response in the metal detector, allowing it to detect their presence.

Old coins are some of the most common things people find while metal detecting. Lost coins are everywhere, making them easy targets if you're just starting out.

Question: Can metal detectors find diamonds? Answer: This leads to an important point: Metal Detectors will not detect non metal items such as gemstones, diamonds and pearls. What a metal detector can do is lead you to indicator minerals, which are used by prospectors.

15 kHz - A good general treasure detecting mode. 20 kHz - Ideal for general treasure detecting and gold prospecting. 40 kHz - Optimum sensitivity to very small gold nuggets.

Gold is element 79 and its symbol is Au.

What metal detector has the best depth? ›

Depth: The Gemini 3 has been expertly created to find deep objects; depending on ground mineralization and object size, targets may be detected 10 to 20 ft. Perfect for Cache Hunting and Relic Hunting. Small things can be found about 3 feet down, medium-sized things at 10 feet, and big things at 20 feet.

Minelab Underwater Metal Detectors

The multi-frequency Excalibur II is their specialized detector for scuba divers, being waterproof to 66m/200ft.

This metal detector can be used almost anywhere regardless of outside interference or ground mineralization - and find treasures buried anywhere from 4ft. to 20ft. deep! Whether you're hunting for a cache of coins or you need the precise location of an underground pipe, the TM 808 does it all.

The simple answer is "as deep as the diameter of the coil". So detectors with larger coils will detect deeper. Large targets can be detected deeper than small targets.
