Product Description

High Depth Ground Metal Detector Machine

    The VLF-81 underground metal detector is a high depth underground super scanner. Normally,the detecting depth of underground mine detector depends on the size of target,but VLF-81 underground pipe locator owns high detecting depth in detecting gold nuggets. The gold metal detector for hobby has the highest possible sensitivity to tiny goldnuggets.

Introduction

 

VLF81 underground gold metal detector isunique among gold prospecting metal detectors for its combination of highsensitivity to small gold nuggets and its versatile function as an all-purposetreasure detector.

 

Thecontrols and features are tailored to gold prospecting, including a sophisticatedground balancing system, separate control over signal gain and threshold, and aunique discrimination control system. These features also make for a greatrelic-hunting detector, especially when it is outfitted with the optional 11″DD search coil. While the VLF-81 makes for a highly competent coin-shootingdetector, its user interface and features are not specifically designed forthis purpose. As a coin-shooter, you will notice that the VLF-81 exhibitsslightly lower sensitivity to high conductivity coins, like a U.S. quarter;this is a result of its specialized design to emphasize sensitivity to smalllow conductivity metals like

goldnuggets.

 

VLF81 isoutfitted with a small 5″ search coil as standard equipment since this search coilconstruction is best-suited to finding gold nuggets. You may be familiar withother metal detectors which have larger search coils, generally in the range of8 to 10 inches in diameter. Large coils are designed to cover the maximumamount of ground efficiently and for the deepest ground penetration. Smallsearch coils, intended for gold prospecting, are designed for precision. Iissmall DD search coil makes pinpointing easier, fits into small spaces wheregold is often hidden, is better suited to penetrate highly mineralized soilswhere gold is frequently found, and has the highest possible sensitivity totiny gold nuggets.
