Professional Metal Detector High Performance Underground Metal Detector TX-850 Underground Depth 2.5m Scanner Search Finder Gold Detector Treasure Hunter Detecting Pinpointer
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.
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 thesearchcoilawayfromappliances such as computers, televisions and microwave ovens. If your detector beeps erratically, turn off appliances and lights.
Also keep the search coil away from objectsco ntainingmetal,suchasfloors and walls.
3): Usea9-voltALKALINEbattery only. Do not use Heavy Duty Batteries.
Introduction to the TX-850 DEEP PENETRATING GOLD NUGGET HUNTER
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 allpurpose 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 aunique discrimination control system. These features also make foragreatrelic-hunting detector. WhiletheTX-850 makes fora highly competentcoin-shootingdetector,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,likeaU.S. quarter; this is a resul to fits specialized design to empha-size sensitivity to small, low conductivity metals like gold nuggets.

SEARCH TECHNIQUES
Target Verification
After detecting a target, do the following:
1. Walk around the target in acircle.
2.While circling the target, conttinue sweeping the search coil across the target.
3.Sweep once every 30° or 40° of the circle.
If the tone does not change and the Target-ID value is consistent as you circle the target, you can be highly confident of the target’s identification.
If the tone or Target-ID changes as you circle the target,you may have multiple targets or an irregularly shaped object.
If the tone completely disappears at different angles, the target may be trash or a low- valuemetal.
If you are new to the hobby, dig all targets. With practice in the field, you will soon be able to correlate audible and visual target feedback with certain types of metal objects.
Pinpointing in Discrimination Mode:
1. Sweep over target in narrowing side-to-side pattern.
2. Takevisual note of spot on ground where “beep” occurs.
3. Step 90° to the side of the target.
4. Sweep searchcoil over same area, at 90° to 1st sweep pattern.
5. This pinpoints the target location with an “X.”
TARGET PINPOINTING
After you have identified a target using Discrimination Mode,press-and-hold the PINPOINT button to identify the target’s exact location. This technique can yield more information about the target’s shape and size and also find its exact location to facilitate extraction.
Pinpoint as follows:
1. Position the searchcoil just barely off the ground, and to the sideof the target.
2. Now move the searchcoil slowly across the target; you can locate it by the sound. The target is located directly under where the sound is loudest.
Narrow It Down:
1. Tonarrow the response further, position the center of the searchcoil
near the center of the response pattern, but not directly over the
center.
2. Release the PINPOINT button.
3. Press-and-hold PINPOINT button again.
4. Repeat this narrowing procedure to narrow the field of detection further.
Note: Depth indication is less accurate after narrowing

Product information:
TX-850L high-sensitivity design, searching for the smallest gold nugget, searching for objects and coil shooting, searching
Can be used for undiscovered treasures in backyards, coastlines, mountains or far away, detectors
Allows you to experience the excitement of treasure hunting.
The search coil is waterproof, but the control enclosure is not waterproof.
This
TX-850L with a large 12-inch coil is unique among gold-detecting metal
detectors because it combines high sensitivity to small gold nuggets and
multi-functions as a general treasure hunting detector.
This TX-850L is an upgrade to the TX-850 with backlight mode function than the TX-850
The
controls and functions are specifically tailored for gold mining
exploration, including a complex ground balance system, individual
control of signal gain and threshold, and a unique identification
control system. These features also make an excellent relic search
detector. Although the TX-850L is a powerful coin detector, its user
interface and functions are not specifically designed for this purpose.
As a coin holder, you will notice that TX-850L is slightly less
sensitive to highly conductive coins, such as the US 15-cent coin; this
is the result of its special design, emphasizing on small and
low-conductivity metals (such as gold). Block) sensitivity.
application:
Gold detection, desert detection, military use, security inspection, archaeology, treasure hunt, beach detection
Features:
1.
TX-850L metal detector has high sensitivity and strong detection
ability. With this metal detector, you can search for coins, artifacts,
jewelry, gold and silver anywhere.
2. Identification-When the
detector emits different tones to different types of metals, and when
the detector "rejects" certain metals, we call it the detector
"identify" different types of metals.
3. Precise
positioning-Precise positioning is the process of finding the exact
location of buried objects. The buried metal appears to the naked eye
exactly the same as the surrounding soil, so it is difficult to separate
it from the soil.
4. LCD display: display possible metal types, target depth, DISC & NOTCH range, SENS level and battery status.
5.
Ground balance-Ground balance is the ability of the detector to ignore
or "see through" the minerals naturally present on the earth, and only
make a sound when a metal object is detected.
6. Target
ID-Different types of metals are classified on a scale of 0-100 from
left to right along the arc at the top of the screen. A 2-digit digital
readout is also provided in the middle of the display for more accurate
target recognition during recognition
