This detector is renowned for its ability to pinpoint a wide range of targets, from modern coins to ancient relics and even small gold pieces. Understanding what it excels at will help you focus your efforts and manage your expectations for essential finds.
The AT Pro is particularly adept at identifying shallow to mid-depth targets with remarkable accuracy. Its discrimination features allow you to filter out unwanted junk while still picking up valuable items. This balance is crucial for maximizing your time in the field and increasing the likelihood of unearthing truly significant finds.
Coins: From Pocket Change to Curiosities
Coins are often the most common finds for metal detectorists, and the AT Pro is an excellent machine for unearthing them. Its high operating frequency and excellent target separation capabilities mean it can distinguish between different coin types, even when they are close together. I’ve pulled everything from modern clad coins to older silver and copper pieces with this detector.
The AT Pro’s Iron Audio feature is a lifesaver when hunting in trashy areas, helping you distinguish between iron junk and desirable targets. This feature provides an audible cue for iron, allowing you to make a quick decision without digging. This saves time and prevents you from filling your finds pouch with unwanted debris.
Relics: Whispers from the Past
The AT Pro Garrett metal detector truly shines when it comes to relic hunting. Its sensitivity and depth capabilities allow it to pick up on buried artifacts that might have been missed by less capable machines. I’ve found old buttons, buckles, musket balls, and even fragments of pottery, each telling a silent story of bygone eras.
Its Ground Balance feature is critical for relic hunting in mineralized soil, which can often mask the signals of buried objects. The AT Pro’s automatic and manual ground balancing options allow you to adapt to various soil conditions, ensuring you don’t miss those faint, deep targets. This adaptability is what makes it such a reliable tool for historical exploration.
Jewelry: The Sparkle of Lost Treasures
Lost jewelry, whether it’s a dropped wedding band or an antique brooch, is another exciting category of finds for AT Pro users. The detector’s sensitivity to small, conductive targets means it can detect the glint of gold, silver, and precious stones. Its notch discrimination allows you to ignore certain types of trash while still alerting you to the presence of jewelry.
When hunting for jewelry, I often adjust the sensitivity settings to their highest stable level. This maximizes the detector’s ability to pick up even the faintest signals from these often small and valuable items. Remember, patience and careful sweeping are key when searching for lost adornments.
Gold: Prospecting Potential
While not primarily a dedicated gold prospecting detector, the Garrett AT Pro can certainly locate small gold nuggets and gold jewelry. Its higher frequency range is more sensitive to the electrical conductivity of gold. For those interested in exploring local gold-bearing areas, the AT Pro can be a surprisingly capable tool.
When prospecting for gold, I focus on areas known for historical gold activity, such as old streambeds or mining sites. The AT Pro’s waterproof design is also a huge plus for prospecting in creeks and rivers. Its ability to discriminate against iron helps differentiate potential gold signals from iron-rich black sands.
Mastering the AT Pro: Settings for Essential Finds
Achieving great finds with your AT Pro Garrett metal detector is heavily reliant on understanding and utilizing its settings. It might seem complex at first, but with a little practice, you’ll be able to dial in the perfect configuration for various hunting scenarios. I always recommend starting with the factory presets and then making small adjustments based on your environment.
Here’s a breakdown of some key settings and how they relate to maximizing your essential finds:
Sensitivity: Pushing the Depth Limits
Sensitivity controls how deep your detector can “see” into the ground. While higher sensitivity can detect deeper targets, it can also lead to false signals in areas with high electromagnetic interference or mineralization. I typically start with a medium-high setting and increase it if the ground conditions allow.
If you experience chattering or erratic signals, it’s a sign that the sensitivity is too high for the conditions. In such cases, reducing it slightly will often stabilize the detector and allow you to pinpoint targets more accurately. Finding that sweet spot is crucial for consistent performance.
Discrimination: Filtering Out the Junk
Discrimination allows you to set the detector to ignore certain types of metal, most commonly iron and foil. For general coin and relic hunting, I usually set my discrimination to exclude iron but accept all other metals. This allows me to hear deeper iron targets that might be masking something valuable.
The AT Pro’s custom discrimination modes are particularly useful. For instance, you can create a profile that ignores common trash items while still alerting you to desirable metals like copper and silver. This fine-tuning significantly improves your efficiency in the field.
Ground Balance: Adapting to the Earth
Ground balance is critical for neutralizing the effects of minerals in the soil, which can cause false signals. The AT Pro features both automatic and manual ground balancing. For most situations, the automatic ground balance is sufficient and easy to use.
However, in highly mineralized areas, manual ground balancing can offer superior performance. This involves pumping the coil up and down while the detector re-balances itself. Mastering this setting can unlock deeper targets in challenging soils. You can learn more about the importance of ground balancing on Garrett’s official website.
Notch Discrimination: Targeted Exclusion
Notch discrimination takes discrimination a step further by allowing you to exclude specific segments of the conductivity scale. This is incredibly useful for eliminating common trash items like pull tabs or small pieces of aluminum foil without ignoring other potentially valuable targets. I often “notch out” the signal range for pull tabs.
By carefully listening to the tones associated with different targets, you can learn to identify specific items. This knowledge, combined with notch discrimination, allows you to make more informed decisions about whether to dig, thereby saving you time and effort.
The Power of Accessories: Enhancing Your AT Pro Experience
While the Garrett AT Pro is a fantastic detector on its own, a few key accessories can significantly enhance your hunting experience and increase your chances of making those essential finds. These additions aren’t just optional extras; they are often crucial tools for serious detectorists.
Pinpointers: The Key to Quick Recovery
A good pinpointer is arguably the most important accessory for any metal detectorist. Once you’ve located a target with your main detector, a pinpointer helps you quickly and accurately pinpoint its exact location within the dug plug of soil. This dramatically reduces digging time and the risk of damaging your finds.
I never leave home without my Garrett Pro-Pointer AT. Its waterproof design complements the AT Pro perfectly, and its sensitivity allows me to locate even tiny targets in seconds. This is a game-changer for efficient recovery.
Coils: Expanding Your Detector’s Capabilities
While the AT Pro comes with a capable 8.5″ x 11″ DD coil, investing in additional coils can unlock new hunting possibilities. Smaller coils offer better target separation in trashy areas and are excellent for pinpointing tiny targets. Larger coils can provide greater depth on larger targets.
For relic hunting in iron-infested sites, a smaller coil like the Garrett 5″ x 8″ DD coil can be invaluable. It allows you to isolate signals more effectively. Conversely, for open fields where depth is paramount, a larger coil might be considered.
Digging Tools: Essential for Recovery
Proper digging tools are essential for recovering your finds without damaging them or the environment. A sturdy digging trowel or a specialized digging tool with a serrated edge is necessary for cutting clean plugs. A sand scoop is indispensable for beach hunting.
I personally prefer a robust, stainless steel digging trowel with a comfortable handle. For beach hunting, a durable sand scoop with a long handle makes the process much more manageable and efficient. Always remember to fill your holes neatly!
Where to Hunt: Maximizing Your AT Pro Garrett Metal Detector Finds
The best metal detector in the world is useless without good hunting locations. The AT Pro’s versatility means it can be used in a wide variety of environments, but some locations tend to yield more interesting finds than others. Research and permission are key to successful and ethical detecting.
Parks and Public Spaces: High Traffic, High Potential
Parks, schoolyards, and other public areas that have been around for a long time are often excellent places to hunt for lost coins and jewelry. People frequent these locations, and items are inevitably dropped. Always check local regulations regarding metal detecting in public spaces and seek permission if necessary.
I’ve had great success in older city parks, finding a variety of coins and even some interesting old buttons. The AT Pro’s ability to handle moderate trash makes these busy locations manageable.
Old Homesteads and Historical Sites: A Glimpse into the Past
Exploring former homesteads, old farm fields, and known historical sites can lead to significant relic finds. These locations are treasure troves of history, offering a chance to uncover artifacts from earlier eras. Always obtain explicit permission from landowners before detecting on private property.
Remember to be respectful of these sites. Dig carefully and fill your holes to leave the area as you found it. Understanding the history of the site can also give you clues about what types of artifacts you might find.
Beaches and Waterways: The AT Pro’s Waterproof Advantage
The AT Pro’s fully waterproof design opens up exciting opportunities for hunting in rivers, lakes, and oceans. Beaches, in particular, are prime locations for finding lost jewelry and coins due to the constant activity of beachgoers. The surf and shifting sands can also unearth previously buried items.
When hunting in water, always prioritize safety. Wear appropriate gear, be aware of currents, and never hunt alone in challenging water conditions. The AT Pro’s waterproof nature provides peace of mind in these environments.
Identifying Target Signals: What Your AT Pro is Telling You
One of the most challenging aspects of metal detecting is interpreting the signals your detector provides. The AT Pro offers a range of tones and numerical target IDs to help you distinguish between different types of metal. Learning to associate these with specific finds is a skill that develops with practice.
Understanding Tones: A Symphony of Signals
The AT Pro uses a multi-tone audio system, with different tones corresponding to different types of metal. Generally, a low-pitched tone often indicates iron, while mid-range tones can be coins and jewelry, and high-pitched tones often signal desirable targets like silver or certain coins. Paying close attention to these tones is crucial.
I often listen intently to the audio response. A clean, sharp signal is usually a good sign of a solid target. A broken or jumpy signal might indicate trash or a difficult-to-identify object.
Target ID Numbers: A Numerical Clue
The Target ID numbers displayed on the AT Pro’s screen provide an additional layer of information about the conductivity of the detected metal. While not always definitive, these numbers can offer a strong indication of what you might be digging. For example, coins typically fall within a certain range.
It’s important to remember that target ID numbers can be influenced by target depth, size, and orientation, as well as soil mineralization. Therefore, it’s always best to combine the audio cues with the visual ID and your own experience. I always recommend digging a few questionable targets early on to calibrate your understanding of the numbers and tones.
Advanced Tips for Maximizing Your AT Pro Garrett Metal Detector Finds
Once you’re comfortable with the basics, there are always ways to refine your technique and squeeze even more performance out of your AT Pro Garrett metal detector. These advanced tips can help you uncover those deeper, more elusive treasures.
Sweep Speed and Overlap: The Rhythm of Detection
The speed at which you sweep your coil over the ground is critical. Sweeping too fast can cause you to miss targets, especially deeper ones. Conversely, sweeping too slowly can lead to an overwhelming amount of signals.
I aim for a consistent, moderate sweep speed, ensuring that each pass of the coil overlaps the previous one by about half the coil’s width. This systematic approach ensures no area is missed and that all targets are properly scanned. Think of it like mowing a lawn – you want complete coverage.
Iron Masking: The Detective’s Dilemma
Iron masking occurs when a desirable target is buried very close to a piece of iron. The iron signal can overpower or mask the signal of the valuable item, leading to it being overlooked. The AT Pro’s Iron Audio and Pro Mode can help mitigate this.
In Pro Mode, you can often hear faint, higher-pitched signals within the iron tone, indicating a potential non-ferrous target nearby. This requires careful listening and sometimes a slower sweep. It’s a skill that takes practice but can yield incredible results.
Research and Reconnaissance: Know Your Hunting Ground
Before you even turn on your detector, doing your homework can dramatically improve your success rate. Researching the history of an area – looking for old maps, historical records, or even local legends – can point you towards promising locations. This is especially true for relic hunting.
Understanding the types of activities that took place in an area can give you clues about what you might find. For example, an old picnic spot might yield more coins, while an old battlefield would be a prime location for military relics.
