This rugged model is so efficient and user friendly, sensitivity is maintained without operator adjustments to the circuitry. The entire line of Bounty Hunter metal detectors operate on two 9-Volt batteries (not included) and are designed to be lightweight and ergonomic for easy handling and comfortable use. Their standard motion all-metal mode detects all types of metal, while the progressive discrimination control eliminates iron and other unwanted items. As a target nears, the Fast Tracker's two-tone audio feedback aids in distinguishing between valuables and undesirable metals. This model also comes equipped with a 1/4 " headphone jack compatible with most headphones (not included) for privacy while treasure hunting. In addition, Bounty Hunter equips all their metal detectors with a preset ground balance that neutralizes the response to mineral content in the ground.
