Bounty Hunters Teknetics G2 Metal Detector is unique among gold prospecting metal detectors for its combination of high sensitivity to small gold nuggets and its versatile function as an all-purpose treasure detector. The controls and features of the Bounty Hunter Teknetics G2 Metal Detection Device 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 this metal detector makes for a 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 there is a slightly lower sensitivity to high-conductivity coins, like a U.S. quarter, this is a result of its specialized design to emphasize sensitivity to small, low conductivity metals like gold nuggets.
