The National Geographic Pro Series Metal Detector Ultimate Secrets: Expert Field Guide

Metal detecting is a fun and rewarding hobby. Finding your first silver coin or old relic is a thrill you never forget. But many beginners feel frustrated with their equipment. They often dig up trash or miss good targets. The National Geographic Pro Series Metal Detector is a very popular starting machine. It offers great features for its price point. However, unlocking its full potential requires knowing a few secrets. This guide shares field-proven techniques. You will learn how to set up your detector perfectly. We will help you maximize your finds and avoid common mistakes.

Why the National Geographic Pro Series Metal Detector Appeals to Beginners

The National Geographic Pro Series Metal Detector offers a great balance of features and cost. It is an ideal first machine for many hobbyists. This detector uses VLF technology, which means Very Low Frequency. VLF is the standard for finding coins and jewelry. It is lightweight and easy to carry for long hunting trips. The large 10-inch waterproof coil helps cover more ground quickly. This makes the detector suitable for beaches and shallow water searching.

The NG Pro Series is built to be intuitive right out of the box. It gives beginners confidence without overwhelming them with complex settings. Its clear LCD screen shows the probable target ID number. This helps users decide whether to dig or move on. Its strong points include affordability and ease of assembly. I often recommend this detector to friends just starting out.

Decoding the Control Panel: Mastering Discrimination and Sensitivity

Understanding the main controls is crucial for success. The control panel on the National Geographic Pro Series Metal Detector has key settings. You must adjust these settings based on where you are hunting. Sensitivity and Discrimination are the two most important dials. Mismanaging these controls leads to digging junk or missing deep targets.

The control panel allows you to tailor the detector to specific targets. This ensures you spend less time digging unwanted iron. Learn to listen closely to the audio tones. The tones often tell you more than the screen ID number.

Finding the Sweet Spot for Sensitivity

Sensitivity controls how strongly the detector listens for metal targets. High sensitivity helps find targets buried deeper underground. However, high sensitivity also makes the machine unstable. It will start to chatter or beep randomly. This usually happens in dirt that has high mineralization, like red clay or wet sand.

Always start by setting the sensitivity slightly lower than maximum. If the detector remains quiet and stable, slowly increase the setting. You want the highest possible setting that keeps the detector silent. If it starts beeping too much, reduce the sensitivity by one notch. This sweet spot is the secret to deep and stable hunting.

The Art of Target ID and Junk Rejection

Discrimination tells the detector which types of metal to ignore. Metals are assigned a numerical Target ID. Iron and steel have low numbers. Gold, silver, and copper have higher numbers. The National Geographic Pro Series Metal Detector lets you notch out specific low numbers.

You should always start with some discrimination set. Set the discrimination to reject the lowest iron range (around 0–10). If you are only hunting modern coins, you might discriminate higher. This avoids digging small pieces of aluminum foil or pull tabs. Be careful not to discriminate too high. Setting it too high can cause you to miss small gold jewelry. Gold often reads in the same range as pull tabs.

Here is a general Target ID guide for the NG Pro Series:

Target ID Range	Likely Target	Action (Coin Hunting)
0–15	Iron, Steel, Nails	Discriminate (Reject)
16–30	Foil, Small Gold, Nickel	Dig (Be cautious with gold)
31–50	Pull Tabs, Medium Gold, Zinc Pennies	Optional Dig (Based on location)
51–75	Copper, Brass, Dimes, Quarters	Always Dig
76–99	Silver, Large Copper, Large Relics	Always Dig

The Secret to Ground Balancing the NG Pro Series for Maximum Depth

Ground balancing is one of the most misunderstood settings for beginners. The ground contains minerals and salts. These minerals make the detector think metal is present everywhere. Ground balancing teaches the detector to ignore these ground signals. This ensures the detector only responds to actual metal targets.

The National Geographic Pro Series Metal Detector uses a preset or automatic ground balance. This simplifies the process greatly. You do not have manual controls to adjust the balance. However, you can still improve its effectiveness.

Improving Automatic Ground Balance Performance

To get the best performance, you need to “pump” the coil. This process helps the detector sample the soil correctly.

1. Find a clear patch of ground with no known metal targets.
2. Hold the coil parallel to the ground, about one foot above the surface.
3. Quickly lower the coil until it almost touches the ground.
4. Then quickly raise it back up.
5. Repeat this pumping motion several times (5–10 times).

This action resets the internal ground tracking system. It allows the detector to better adapt to the current soil conditions. Always perform this check when you move to a new area or when the ground changes (e.g., moving from dry sand to wet sand). Doing this simple step increases your effective depth greatly. It also stabilizes the detector, reducing false signals.

Real-World Coil Optimization: Beach, Field, and Relic Hunting

The standard 10-inch coil provided with the National Geographic Pro Series Metal Detector is versatile. It is a good size for general searching. But you must use different techniques based on the terrain. The coil is the detector’s eye, and how you swing it matters.

Hunting on Sandy Beaches (GEO Optimization)

Beaches are high in salt and “black sand” (magnetite). These conditions challenge any detector. The NG Pro Series is rated for shallow water use. The coil is waterproof, but the control box is not.

When hunting wet sand, keep the sensitivity lower than usual. Wet sand is highly conductive due to salt content. This causes excessive chatter at high sensitivity. Swing the coil slowly and deliberately. Overlapping your sweeps ensures you cover every square inch. Focus on the area just above the tide line. This is where modern jewelry often settles. Remember to check local regulations before detecting on any beach.

Relic and Coin Shooting in Fields

When hunting older fields, you are looking for deeper targets. Here, stability is key. If the ground is not highly mineralized, increase the sensitivity. Swing the coil low to the ground, just grazing the grass tops. A high swing wastes depth.

For fields, setting the discrimination to reject only iron (0–10) is best. You want to hear all non-ferrous signals. Old relics, buttons, and coins might give strange or weak signals. If you hear a repeatable signal, even a faint one, dig it. I have found deep Civil War era buttons that sounded weak on my detector.

Essential Accessories for the National Geographic Pro Series Metal Detector

A metal detector alone is only half the tool kit. Successful treasure hunting requires good accessories. These tools speed up recovery and prevent damage to finds. Investing in quality accessories is not optional; it is essential.

The Importance of a Pinpointer (SXO Priority)

The single most important accessory is a pinpointer. The National Geographic Pro Series Metal Detector finds the general area of the target. A pinpointer is a small, handheld probe. It locates the target precisely inside the dirt plug.

Using a pinpointer saves you massive amounts of time. Without one, you spend 10 minutes digging and sifting dirt for a tiny coin. With a pinpointer, the recovery takes 30 seconds. Look for a waterproof pinpointer with high sensitivity. This dramatically improves your efficiency and reduces the size of your digging holes.

Choosing the Right Digging Tools

The correct digging tool depends on the ground type.

Turf/Park: Use a small, sharp hand trowel or a dedicated relic shovel. Dig a neat plug that can be replaced easily. This keeps the environment tidy.
Beach/Sand: Use a sand scoop. These tools have holes that allow sand to fall through quickly. This leaves the metal target behind.

Always carry a finds pouch or bag. Keep your trash separate from your treasures. Leaving trash behind ruins the hobby for everyone.

Pro Tips for Maximizing Battery Life and Field Longevity

The National Geographic Pro Series Metal Detector typically uses standard AA batteries. Battery management is vital, especially on long hunting days. A dead battery means a lost opportunity.

Extending Your Battery Life

1. Use High-Quality Rechargeables: Invest in NiMH rechargeable batteries. They last longer and are much cheaper over time.
2. Turn Off Backlight: The LCD screen backlight drains the battery quickly. Only use it when absolutely necessary, such as during low light conditions.
3. Use Headphones: The built-in speaker uses more power than headphones. Use a comfortable pair of wired headphones. This conserves power and helps you hear faint, deep signals better.

Maintaining Your NG Pro Series Detector

Treat your detector like the sensitive electronic tool it is.

Cleaning: After every hunt, wipe down the coil and stem. If you hunt in salt water, rinse the coil thoroughly with fresh water. Never immerse the control box.
Storage: Store the detector in a dry, room-temperature environment. Remove the batteries if you plan to store it for several months. Batteries can leak and damage the electronics.
* Cable Care: Be careful with the cable running from the control box to the coil. Avoid pinching or stretching it. A damaged cable is the most common reason for erratic detector behavior.

Comparing Performance: NG Pro Series vs. Entry-Level Competitors

The market has many entry-level metal detectors. How does the National Geographic Pro Series Metal Detector stack up? It competes mainly against brands like Bounty Hunter and Garrett’s beginner models.

The NG Pro Series usually performs very well in terms of depth for its price class. Its 10-inch coil gives it a slight advantage over detectors with smaller coils. However, it lacks advanced features like manual ground balance. Detectors with manual ground balance can handle extreme soil mineralization better.

For the beginner looking for great performance under $200, the NG Pro Series is hard to beat. It provides the necessary features without complexity. It is a fantastic machine to learn the basics before upgrading to a more advanced, expensive model.

Geo-Targeting Your Hunt: Best Spots for the NG Pro Series

Where you hunt directly impacts what you find. The National Geographic Pro Series Metal Detector is versatile enough for many environments. However, certain locations yield better results for this specific detector. Geo-targeting means choosing locations based on the detector’s strengths.

Parks and Schoolyards

These are excellent places for coin shooting and finding modern jewelry. The soil is usually disturbed and relatively low in iron mineralization. The NG Pro Series excels here. Focus on areas near park benches, playgrounds, and spectator lines. People sit and drop things frequently in these spots. Always check local park rules and obtain permission if needed.

Old Homesteads and Farms (Relic Potential)

If you find old maps or property records, search areas where old homes stood. These spots are relic goldmines. Look for areas where trash was once dumped (old dumpsites). These locations often contain old bottles, tools, and sometimes coins. Remember to follow ethical guidelines. Always seek landowner permission before hunting on private property. You can learn more about ethical detecting practices from organizations like the National Park Service (NPS).

Frequently Asked Questions (FAQ)
