2026 New TIANXUN TX-850 TX850L Underground Gold Metal Detector Prospecting Treasure Detector With Carry Bag Headphone Cover

If you do not have prior experience with a metal detector, we strongly recommend that you：

1 ) Adjust the Gain to a low setting in the event of false signals. Always begin use at a reduced Gain level; increase Gain only after you

have become familiar with the detector.

2）Do not use indoors.

This detector is for outdoor
use only.Many household
appliances emit
electromagnetic energy,
which can interfere with
the detector. If conducting
an indoor demonstration,
turn the Gain down and keep
the searchcoil away from appliances such as computers, televisions and microwave ovens. If your detector beeps erratically, turn off appliances and lights.

Also keep the search coil away from objects containing metal, such as floors and walls.

3）Use a 9-volt ALKALINE battery only. Do not use Heavy Duty Batteries.

The New TX-850 is unique among gold prospecting metal detectors for its combination of high sensitivity to small gold nuggets and its versatile function as an all-purpose treasure detector.

The controls and features are tailored to gold prospecting, including a sophisticated ground balancing system, separate control over signal gain and threshold, and a unique discrimination control system. These features also make for a great relic-hunting detector. While the TX-850 makes for a highly competent coin shooting detector, its user interface and features are not specifically designed for this purpose. As a coin-shooter, you will notice that the TX-850 exhibits slightly lower sensitivity to high-conductivity coins, like a U.S. quarter; this is a result of its specialized design to emphasize sensitivity to small, low conductivity metals like gold nuggets.

Product Feature ：

1. Elimination - Reference to a metal being eliminated means that the detector will not emit a tone ,nor light up an indicator

2. Discrimination - Allow thw user to ignore trash and other undersireble objects
