Three Tone Audio Discrimination The detector emits three distinct tones (, medium, and low) to indicate different metal types, enabling quick and intuitive target identification without constant visual checking. Benefit: helps you differentiate metals on the fly, improving find quality and reducing time spent evaluating targets. Notch Notch ignores junk metal and focuses on valuable items by allowing you to set the disc and notch range. Benefit: increases efficiency by filtering out unwanted targets and prioritizing items you care about. Super Slow Sweep Identification Uses a very slow sweep of the search coil to discriminate between metal types with higher precision. Benefit: improves accuracy of target classification, reducing false positives and helping you confirm valuable finds. Headphone Jack 3.5 mm headphone jack for connecting standard headphones (not supplied) and operating quietly and comfortably. Benefit: private listening experience and clearer target signals in noisy environments or when you need to stay discreet. 23 Practical use scenarios Beach and park coin hunting: quickly distinguish coins and jewelry from trash using the threetone feedback, while leveraging notch to ignore common junk targets. Field treasure exploration: use the slow sweep for precise discrimination in grassy or uneven terrain, helping you identify valuable items before digging. Urban or public areas: connect headphones to concentrate on signals without disturbing others, enabling focused searching in quiet or busy environments.
