 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.

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.
