The New TX-850 with bigger search coil is unique among gold prospecting
metal detectors for its combination of high sensitivity to small gold
nuggets and its versatile function as an all purposes treasure detector.
metal detectors for its combination of high sensitivity to small gold
nuggets and its versatile function as an all purposes treasure detector.
Thecontrols 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 fora 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 to fits specialized design to empha-size sensitivity to small,
low conductivity metals like gold nuggets.

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):Donot 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.

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.
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.

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.
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.
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.
