10 Mins Read Metal detecting

Yes, platinum can be detected with a metal detector, but it requires the right equipment and understanding of its properties. This guide covers how platinum behaves with detectors, what settings to use, and the best tools for finding it.

Welcome, fellow treasure hunters! Have you ever wondered about those elusive platinum finds? It’s a question that pops up often: can platinum be detected with a metal detector? The answer is a resounding yes, but it’s not as straightforward as finding a silver coin. Platinum’s unique metallic properties mean it can be tricky, leading many to believe it’s undetectable. Don’t worry, though; with the right knowledge and gear, you can significantly increase your chances of unearthing this precious metal. This guide will walk you through everything you need to know, from understanding platinum’s conductivity to choosing the perfect detector. Let’s get started on uncovering the secrets of finding platinum!

The Unique Properties of Platinum and Metal Detection

Platinum is a noble metal known for its rarity, density, and resistance to corrosion. These characteristics also influence how it interacts with the electromagnetic fields generated by metal detectors. Understanding these properties is key to successfully detecting platinum.

Platinum’s high electrical conductivity, though lower than silver, is still significant enough for most modern metal detectors to register. Its density means it will have a good “target response” when hit by a detector’s signal. However, its conductivity falls in a range that can sometimes overlap with other common metals, making target identification crucial.

Can Platinum Be Detected With A Metal Detector? The Short Answer

Yes, platinum can be detected with a metal detector. While its conductivity is lower than gold, its density and unique electrical signature allow most modern, sensitive metal detectors to pick it up, especially with the right settings and coil.

Most advanced metal detectors are capable of detecting platinum. The challenge lies in distinguishing it from other targets and ensuring your detector is sensitive enough to pick up its specific signal. This often means using specific settings and sometimes specialized coils.

Understanding Metal Detector Frequencies and Platinum

Metal detectors operate on different frequencies, and this is a critical factor when searching for platinum. Higher frequencies are generally better at detecting smaller, low-conductivity targets, while lower frequencies excel with larger, highly conductive targets. Platinum falls into an interesting middle ground.

A frequency range between 10 kHz and 20 kHz is often considered a sweet spot for detecting a variety of metals, including platinum. Detectors operating in this range can balance sensitivity to smaller items with the ability to distinguish between different metallic signatures. Some detectors offer multi-frequency capabilities, which are particularly advantageous for diverse targets like platinum.

The Role of Conductivity in Platinum Detection

Electrical conductivity is how well a material conducts electricity. In metal detecting, this translates to how strongly a target reflects the detector’s electromagnetic signal. Platinum has a conductivity rating that places it between gold and silver, but it’s distinct enough to be identified.

While gold’s conductivity varies greatly by purity, pure gold typically has a lower conductivity than platinum. Silver, on the other hand, is highly conductive. This means a detector might struggle to differentiate between platinum and some other metals if not set up correctly.

What Detector Settings Are Best for Platinum?

Optimizing your metal detector’s settings is paramount when targeting platinum. This involves adjusting sensitivity, discrimination, and ground balance. These adjustments help boost the signal from platinum while minimizing interference from unwanted targets or soil minerals.

Key Settings to Consider:

Sensitivity: Maximize this setting within the limits of your detector to pick up faint signals. Be mindful of false signals from mineralized ground or EMI.
 Discrimination: Use a low discrimination setting or turn it off entirely. Platinum can sometimes register in the same range as iron or foil. Relying on your detector’s tone and VDI numbers is more effective.
Ground Balance: Properly ground balancing your detector to the soil conditions will reduce false signals and enhance target detection. Manual ground balance often offers more control.
 Notch Filters: If your detector has notch filters, experiment with them to ignore specific VDI ranges commonly associated with trash items, but be cautious not to exclude platinum.

Choosing the Right Metal Detector for Platinum

Not all metal detectors are created equal when it comes to finding precious metals like platinum. While many general-purpose detectors can find it, some are specifically designed for enhanced sensitivity to low-conductivity targets or offer advanced features beneficial for platinum prospecting.

Recommended Detector Types:

Multi-Frequency Detectors: These are excellent for platinum because they can simultaneously operate on multiple frequencies, offering a wider range of target detection capabilities. Brands like Minelab (Equinox, CTX 3030) and Nokta Makro (Legend) are great examples.
 High-Frequency Detectors: If you’re specifically looking for very small platinum nuggets or jewelry, a detector with a higher operating frequency (e.g., 20 kHz and above) can be beneficial.
Pulse Induction (PI) Detectors: While often used for highly mineralized ground or saltwater beaches, PI detectors can be very sensitive to all metals, including platinum, and are less affected by ground mineralization.

When I first started out, I used a basic VLF detector and found some interesting targets, but it wasn’t until I upgraded to a multi-frequency machine that I truly started to appreciate the nuances of detecting different precious metals. The ability to sweep across various frequencies opened up a whole new world of finds.

The Importance of Metal Detector Coils for Platinum

The coil is your metal detector’s “eye,” and choosing the right one can dramatically impact your success in finding platinum. Different coil sizes and types are suited for different scenarios and target types. For platinum, you’ll want a coil that offers good sensitivity to smaller targets and can handle varied ground conditions.

Coil Considerations:

Smaller Coils (e.g., 6-8 inches): These are excellent for pinpointing small targets and can be more sensitive to subtle signals from small platinum nuggets or fine jewelry. They also perform better in trashy areas.
Larger Coils (e.g., 11-15 inches): While covering more ground, larger coils might miss very small platinum pieces. However, they can be advantageous for covering larger areas where platinum might be dispersed.
 Double-D Coils: These are generally preferred for their ability to handle ground mineralization better than concentric coils.
High-Frequency Coils: If your detector supports interchangeable coils, a high-frequency coil can be a game-changer for small platinum finds.

Detecting Platinum Jewelry vs. Platinum Nuggets

The form in which platinum is found significantly affects how you detect it. Platinum jewelry, such as rings or necklaces, will typically present a stronger, more consistent signal than small, irregular platinum nuggets scattered in the ground.

Platinum nuggets are often found in areas with placer deposits, similar to gold prospecting. These nuggets can vary greatly in size and shape, making them more challenging to detect, especially if they are very small or deeply buried. Jewelry, on the other hand, usually has a more defined target profile.

Practical Tips for Finding Platinum

Beyond selecting the right equipment and settings, practical techniques and a good understanding of likely locations will greatly improve your platinum hunting success. Patience and persistence are key virtues for any detectorist.

Field Techniques:

Target Analysis: Learn to interpret your detector’s target ID (VDI numbers) and audio tones. Platinum often falls in a specific range, but it can overlap. Always dig questionable signals.
Pinpointing: Use a good pinpointer to accurately locate targets in the dug plug. This saves time and minimizes disturbance to the ground.
 Location, Location, Location: Research areas known for historical mining activity (especially gold and platinum placers), old jewelry shops, or areas where precious metals might have been lost.
Coil Control: Swing your coil smoothly and at a consistent height over the ground. Overlap your sweeps to ensure complete coverage.
 Water Prospecting: If you’re near rivers or streams in known platinum-bearing regions, specialized waterproof detectors and coils can be used for detecting in shallow water.
