$96.98
Price: 138.55 - 96.98
If you have no previous experience with a metal detector, we strongly recommend that you:
1): If there is an error signal, turn down the gain setting.
2): Do not use it indoors. This detector is for outdoor use only. Many household appliances emit electromagnetic energy that can interfere with detectors. If giving an indoor presentation, turn down the gain and keep the search coil away from equipment such as computers, TVs, and microwaves. 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): Only use 9 volt alkaline batteries. Do not use heavy batteries.
Introduction to TX-850 Deep Penetration Nugget Hunter
The New TX-850 is unique among gold prospecting metal detectors because it combines high
Sensitivity to small nuggets and its versatility as a general purpose treasure hunter.
Controls and features tailored for gold prospecting, including complex ground
Balance system, independent control of signal gain and threshold, unique discrimination
Control System. These features also make for a great relic hunting detector.And the TX-850 makes
For a very capable coin detector, its UI and functionality are nothing special
Designed for this purpose.As a coin hand you will notice that the TX-850 performs slightly
Less sensitive to highly conductive coins such as US Quarters; this is a result for professionals
The design emphasizes size sensitivity to small, low-conductivity metals such as gold nuggets.

search skills
target validation
Once a target is detected, do the following:
1. Walk around the target.
2. While orbiting the target, continue to sweep the search coil across the target.
3. Sweep once every 30° or 40°.
If the pitch does not change, and the Target-ID value remains consistent as you circle the target, you can have high confidence in the target’s identification.
If the tone or target ID changes as you circle around the target, you may have multiple targets or an irregularly shaped object.
If the tone disappears completely at different angles, the target is probably junk or low value metal.
If you’re new to the hobby, dig into all the goals. With field practice, you’ll soon be able to associate auditory and visual target feedback with certain types of metallic objects.
Precise positioning in discriminative mode:
1. Swipe across the target in a zoomed-out left-right pattern.
2. Visually check where the “beep” appears on the ground.
3. Walk 90° to the target side.
4. Scan the search coil over the same area, at 90° to the first scan pattern.
5. This pinpoints the target location with an “X”.
precise targeting
After identifying a target using Discrimination Mode, press and hold the PINPOINT button to identify the exact location of the target. This technique yields more information about the shape and size of the target, and also finds its exact location for easy extraction.
details as follows:
1. Position the search coil just off the ground and to the side of the target.
2. Now slowly move the search coil across the target; you can find it by sound. The target is directly below where the sound is loudest.
narrow down:
1. To further narrow the response range, center the search coil
near the center of the response pattern, but not directly on the
center.
2. Release the PINPOINT button.
3. Press and hold the PINPOINT button again.
4. Repeat this reduction procedure to further reduce the detection range.
NOTE: Depth indication is less accurate when narrowed.
