Hot Rocks and Metal Detectors: Why Some Rocks Produce Signals Hot rocks in metal detecting are rocks that produce a noticeable response because their electromagnetic properties differ from the ground around them and the ground response your detector is compensating for. You may hear a sharp beep, an awkward warble, or a dip in the […]
Metal Detector Audio Tones Explained: How to Understand Target Sounds Metal detector audio tones give you a running description of what the search coil is encountering. A low grunt, a clear bell, a faint rise in sound, or a broken chirp can help you decide where to investigate. The challenge is understanding which information your […]
What Metals Can a Metal Detector Detect? A Complete Guide What metals can a metal detector detect? A conventional search-coil metal detector can respond to many metals, including iron, steel, gold, silver, copper, aluminium, brass, bronze, lead, platinum and titanium. Stainless steel is also detectable, although some grades and small shapes can be challenging. The more […]
Minelab MANTICORE Review: Features, Settings and Buying Guide The Minelab MANTICORE is an advanced metal detector for people who want more information from difficult signals.

Understanding how those functions fit together is more useful […]
Metal Detector Target ID Explained: A Complete Guide to Reading Numbers If you use a modern metal detector, you have probably seen a number appear on the screen when the coil passes over a target. This number is called the metal detector target ID. It can help you decide whether a signal may be an iron […]
Why Does My Metal Detector Keep Beeping? Causes and Fixes If your metal detector keeps beeping, start by identifying the sound before changing settings. Random chatter can involve electrical interference, ground conditions, excessive sensitivity or the coil setup. Repeated responses may also come from actual metal you have not located. A steady background hum or an […]
How to Use GR-4 DUAL for Cavities, Voids, and Buried Treasures The GR-4 DUAL, also known in product listings as GR-4 GroundTech, is a 3D ground scanning system designed for users who need visual information about what may be hidden below the surface. Unlike a standard audio metal detector that mainly gives a tone when the […]
Phoenix 3D Ground Scanner: Step-by-Step User Guide The Phoenix 3D Ground Scanner from Mega Detection is designed for users who need more than a conventional metal detector. It is built for ground scanning, treasure investigation, archaeological-style exploration, and cavity detection. According to Orient Detectors and Mega Detection product information, Phoenix includes three search systems: 3D […]

Waterproof Metal Detectors Guide: Beaches, Rivers, Rain, and Wet Ground Introduction: Waterproof Does Not Always Mean Underwater A waterproof metal detector can open excellent search opportunities: beaches after tourist season, shallow river crossings, wet farm fields, lake edges, rainy-day hunts, and jewelry recovery around swimming areas. But the word waterproof is often misunderstood. Some detectors are fully […]
Metal Detector Discrimination Guide: How to Filter Trash Without Missing Good Targets Introduction: Discrimination Is Useful, But It Is Not Magic Metal detector discrimination is the detector’s ability to accept or reject certain target responses. It helps users reduce iron trash, avoid some foil and pull tabs, and focus on the signals most likely to be […]
Metal Detector Ground Balance Guide: Manual, Automatic, and Tracking Explained Introduction: Why Ground Balance Matters More Than Beginners Think Metal detector ground balance is one of the most important settings in real field detecting, yet many beginners ignore it until the detector becomes noisy. A detector may beep over empty ground, lose depth, show unstable target […]
