Understanding the Nokta Anfibio Multi Metal Detector: Key Features Overview

The Nokta Anfibio Multi metal detector is built to be an all-terrain workhorse. It stands out due to its full waterproofing and selectable frequency system. This detector allows users to switch between three different operating frequencies: 5kHz, 14kHz, or 20kHz. This flexibility means you can tailor the detector’s performance to the specific targets you seek. The Anfibio Multi also features an integrated wireless audio system and a deep-seeking capability, making it a serious contender for professional and dedicated hobbyists alike.

This detector combines high-end features with user-friendly controls. It offers excellent depth and target identification even in trashy areas. The durable design ensures it can handle harsh conditions, from muddy fields to saltwater environments. It truly is a versatile machine designed for global use.

The Power of Selectable Multi-Frequency Operation

The term “multi-frequency” can be confusing for beginners. The Nokta Anfibio Multi uses selectable multi-frequency, which means you choose one frequency to run at a time. Low frequencies (like 5kHz) penetrate deeper and are better for large, high-conductive targets like large silver coins or relics. Mid-range frequencies (14kHz) offer a great balance for general coin and jewelry hunting. High frequencies (20kHz) are superb for finding tiny, low-conductive targets, such as small gold nuggets or thin hammered coins.

By letting you pick the best frequency, the Anfibio Multi ensures maximum efficiency. You are not stuck using a general setting that compromises performance. You can quickly adapt to the ground conditions and target type, which is essential for successful treasure hunting. This adaptability is a major reason why many experienced detectorists trust the Anfibio platform.

Frequency (kHz)	Best Use Case	Target Type Focus
5 kHz	Deep Relic Hunting, Cache Hunting	Large copper, brass, and silver items; maximum depth.
14 kHz	General Coin and Jewelry Hunting	Medium-sized targets, good depth and sensitivity balance.
20 kHz	Small Gold Nuggets, Fine Jewelry, Beach Micro-Jewelry	Very small, low-conductive targets; high sensitivity.

Deep Dive into Technology: Waterproofing and Construction

One of the Nokta Anfibio Multi metal detector’s most celebrated features is its IP68 waterproofing rating. This rating means the detector is dust-tight and fully protected against continuous immersion in water. Specifically, the Anfibio Multi can be submerged up to 5 meters (16.4 feet) deep. This makes it ideal for shoreline hunting, wading in streams, or even scuba diving for submerged relics.

The construction uses durable materials that resist corrosion from saltwater and sand. The shaft system is telescopic, allowing for quick adjustments and easy breakdown for transport. The detector is also relatively lightweight for a professional machine, reducing fatigue during long hours in the field. This rugged build quality ensures the detector performs reliably in any extreme environment you choose to explore.

Mastering the Frequencies: Best Settings for Different Targets

To maximize your finds with the Nokta Anfibio Multi metal detector, you must learn when to use each frequency. Switching frequencies is simple, but knowing the context is key. Always start with the 14kHz setting for general hunting until you understand the site’s potential. Then, adjust based on the expected targets and ground mineralization.

Choosing the correct frequency dramatically improves target separation and depth. Using 20kHz in a field where you expect large iron relics will only make the detector noisy and reduce your depth. Conversely, using 5kHz on a gold prospecting site might miss those tiny, valuable flakes. Always match the tool to the task.

Coin and Relic Hunting Settings

For hunting old coins and medium-to-large relics, the 14kHz frequency is often the sweet spot. It provides excellent depth while maintaining good sensitivity to standard-sized coins. If you are specifically hunting deep, large military relics, switch to 5kHz for maximum penetration. Ensure your discrimination setting is high enough to reject small iron trash but low enough to accept desirable low-conductive targets like lead or brass buttons.

I recommend setting the recovery speed slightly lower (2 or 3) when searching for deep, isolated targets. Lower recovery speed allows the detector more time to process faint, deep signals. If you are in a park full of modern trash, increase the recovery speed (4 or 5) to quickly separate desirable targets from the junk.

Gold Prospecting Settings

Gold prospecting requires maximum sensitivity because gold nuggets are often small and have low conductivity. Use the 20kHz frequency exclusively for gold hunting. This high frequency is highly sensitive to tiny changes in conductivity, picking up even sub-gram pieces of gold. Gold sites often have highly mineralized ground, so proper ground balancing is critical.

When prospecting, use the “Deep” mode if the ground allows, or the “Park 2” mode if you need more speed in trashy areas. Keep your sensitivity as high as possible without causing constant false chatter. You must listen closely for those faint, high-pitched signals that indicate small gold targets. Always check your pinpointer settings, as tiny gold can be hard to locate once dug.

Real-World Performance: Depth, Sensitivity, and Recovery Speed

The Nokta Anfibio Multi metal detector consistently delivers impressive depth, often rivaling machines in higher price brackets. Its depth performance is strongest when using the 5kHz frequency on low-mineralized ground. The detector’s stable performance in mineralized soil is achieved through sophisticated automatic and manual ground balance controls, ensuring minimal signal loss.

Sensitivity refers to the detector’s ability to pick up small targets. At 20kHz, the Anfibio Multi is incredibly sensitive, making it excellent for finding thin jewelry chains or tiny relics. Recovery speed—how fast the detector processes one target and is ready for the next—is highly adjustable. High recovery speed (4 or 5) is crucial for hunting in iron-infested sites or trashy parks, ensuring you don’t miss good targets lying right next to nails.

I have personally found that adjusting the recovery speed correctly is the key to unlocking the Anfibio’s true potential. In extremely trashy areas, a fast recovery speed prevents target masking. This feature significantly increases your chances of finding valuable coins or rings hidden among modern debris.

Essential Accessories and Coils for the Anfibio Multi

While the Nokta Anfibio Multi metal detector comes standard with the AF28 (11-inch DD) coil, expanding your coil arsenal dramatically improves versatility. Different coils serve different purposes, optimizing performance for specific hunting conditions. Choosing the right coil is as important as choosing the right frequency.

Smaller coils, like the AF13 (5-inch DD), offer exceptional target separation and are perfect for extremely trashy areas or searching bedrock crevices for gold. Larger coils, such as the AF35 (13.5×13-inch DD), provide maximum ground coverage and depth, making them ideal for searching large, clean fields or beaches. The detector also supports wireless audio, typically using the included 2.4 GHz Green Edition wireless headphones. Wireless freedom is essential when swinging a large coil for hours or detecting underwater.

• AF28 (11″ DD): Standard, versatile coil; good balance of depth and coverage.
• AF13 (5″ DD): Excellent for high-trash areas and gold snipers; best target separation.
• AF35 (13.5″x13″ DD): Maximum depth and ground coverage; best for clean fields and beaches.
• Waterproof Headphones: Necessary for submerged detecting; ensures clear audio feedback underwater.

Ground Balance and Discrimination: Avoiding False Signals

Proper ground balance is arguably the most critical setting for any VLF detector, including the Nokta Anfibio Multi metal detector. Ground balance cancels out the magnetic signals from the soil itself, which prevents annoying false signals (chatter). Highly mineralized ground, like red clay or wet saltwater sand, requires precise ground balancing to maintain depth and stability. The Anfibio offers automatic, manual, and tracking ground balance options.

Discrimination is the process of ignoring unwanted targets, usually iron. The Anfibio Multi uses a numerical Target ID (TID) system, typically 0 to 99, to indicate the conductivity of the detected target. Lower numbers (0–10) are usually iron, while higher numbers indicate valuable metals. Learn the TID ranges common to your area. For instance, in the US, silver coins often register in the high 80s or 90s.

I always recommend running a minimum discrimination setting. Too much discrimination can cause valuable targets to be missed if they are masked by iron or lying at odd angles. Set your discrimination just high enough to knock out surface nails, but listen to all targets. You can learn more about advanced discrimination techniques on reputable detecting forums.

Step-by-Step Setup Guide for Beginners

Getting the Nokta Anfibio Multi metal detector ready for your first hunt is straightforward. Follow these steps to ensure optimal performance from the start:

1. Assembly: Attach the coil to the lower rod, connect the middle rod, and slide the control box onto the upper shaft. Secure all connections tightly, especially the coil cable plug, to maintain waterproofing.
2. Power On and Volume: Press the power button. Adjust the volume to a comfortable level, especially if using the wireless headphones.
3. Select Frequency: Choose your target frequency (5, 14, or 20 kHz). For general park hunting, start with 14 kHz.
4. Choose Mode: Select a suitable search mode (e.g., General, Park 1, Beach). Park 1 is great for beginners in high-trash areas.
5. Ground Balance: Perform an automatic ground balance. Hold the coil about a foot off the ground. Press and hold the GB button while pumping the coil up and down slightly. Release the button when the detector stabilizes and gives an audible confirmation.
6. Set Sensitivity: Start sensitivity at the factory default or slightly lower (around 70–80). Increase it slowly until the detector starts chattering, then back it off one notch for maximum stable depth.
7. Start Sweeping: Sweep the coil slowly and smoothly, overlapping each swing slightly. Listen for repeatable, crisp signals that produce a stable Target ID.

Remember that practice is essential. Spend time learning the sounds and IDs in clean test areas before heading out to complex sites. Consistency in your swing speed also dramatically improves the detector’s ability to identify targets correctly.

Always rinse the detector thoroughly with fresh water after detecting in saltwater or muddy conditions. Salt residue can damage O-rings and connections over time.

Pay close attention to the coil cable connection point. Even though the machine is waterproof, sand or debris trapped in the threads can compromise the seal. Clean the threads gently before reconnecting. Regularly check the battery compartment seal and apply a small amount of silicone grease to the O-rings periodically. Store the detector in a cool, dry place and avoid leaving it exposed to extreme heat inside a vehicle for long periods. Proper care guarantees the IP68 rating remains intact for all your future underwater adventures.

For longevity, always use the provided coil cover. This protects the sensitive coil surface from scratches and abrasion, which can lead to noise or signal loss over time. Treat your detector like the sensitive electronic instrument it is.
