Congratulations!
Congratulations on your purchase of the new TIANXUN® TX-850 metal detector. The
newly designed TX-850 has been custom designed to find the smallest gold nuggets, but
unlike other specialized gold prospecting detectors, it can also be used for relic-hunting
and coin-shooting.
Whether you use your detector in the backyard, at the shoreline, in the mountains of
field’s afar, your investment will let you experience the excitement of searching for yet
uncovered treasures and give you hours and years of outdoor enjoyment. Out on your
own or with a group, places to use your TX-850 are unlimited as buried treasures can be
as near as your doorstep or as far as you wish to travel.
This manual has been written to help you get optimal use of your detector, so we hope
you will read it thoroughly before you first outing and will also refer back to this manual
from time to time to reinforce features and methods as you become proficient in the
field.
If you do not have prior experience with a metal detector, we strongly recommend that
you:
•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.
•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 search coil away from appliances such a computers,
televisions and microwave ovens. If your detector beeps erratically, turn off appliances
and lights.
Also keep the search coils away from objects containing metal, such as floors and walls.
•Use a 9-volt ALKALINE battery only.
Do not use Heavy Duty Batteries.

Introduction to the TX-850
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 U.S. quarter, this is a result of its specialized design to emphases-size
sensitivity to small, low conductivity metals like gold nuggets.

Terminology
The following terms are used throughout the manual, and are standard technology
among treasure hunters.
•Elimination
Reference to a metal being “eliminated” means that the detector will not emit a tone, nor
light up an indicator, when a specified object passes through the search coil’s detection
field.
•Discrimination
When the detector emits different tones for different types of metal, and when the
detector “eliminates” certain metals, we refer to this as the detector “discriminating”
among different types of metals.
Discrimination is as essential feature of professional metal detectors. Discrimination
allows the user to ignore trash and other undesirable objects.
•Relics
A relic an object of interest by reasons its age or its association with the past. Many relics
are made of iron, but can also be made of bronze or precious metals.
•Iron
Iron is a common, low-grade metal that is an undesirable target in certain metal
detecting applications. Examples of undesirable iron objects are old cans, pipes, bolts
and nails.
Sometimes, the desired target is made of iron. Properly markers, for instance, contain
iron. Valuable relics can also be composed of iron; cannon balls, old armaments, and
parts of old structures and vehicles can also be composed of iron.
•Ferrous
Metals which are made of, or contain, iron.
•Pinpointing
Pinpointing is the process of finding the exact location of buried object. Long-buried
metals can appear to the eye exactly like the surrounding soil, and can therefore be very
hard to isolate from the soil.
•V.C.O.
Meaning “voltage controlled oscillator”, the V.C.O. audio method causes both the audio
pitch and the volume to rise as signal strength increases. V.C.O. improves the user’s
ability to interpret a target’s size and depth. Very weak signals (for small or very deeply
buried objects) have the faintest volume and the lowest pitch. Larger objects and those
closer to the search coil, will induce a higher volume and higher pitch sound.
