What Makes the Nokta Simplex Ultra Special?
The Nokta Simplex Ultra represents a significant upgrade to the already popular Simplex+ platform. Released as an enhanced version, this metal detector combines advanced technology with user-friendly operation, making it suitable for both beginners and experienced detectorists.
The Ultra model features improved discrimination capabilities, better target separation, and enhanced depth detection compared to its predecessor. With a waterproof design that allows submersion up to 16 feet (5 meters), the Simplex Ultra is ready for beach hunting, shallow water detecting, and all-terrain use.
Key Technical Specifications
The Simplex Ultra operates at a frequency of 12 kHz, providing excellent sensitivity to a wide range of targets including coins, jewelry, and relics. The detector weighs just 2.5 pounds (1.13 kg), making it comfortable for extended detecting sessions without causing fatigue.
Battery life is impressive, offering up to 20 hours of continuous use on a single charge. The built-in rechargeable lithium battery can be easily charged via USB-C, eliminating the need for disposable batteries and reducing long-term operating costs.
Performance Features and Capabilities
Advanced Detection Modes
The Nokta Simplex Ultra offers multiple search modes designed for different detecting scenarios. These include:
– All Metal mode for maximum depth and sensitivity
– Field mode optimized for general coin and relic hunting
– Park mode designed for urban detecting with enhanced trash rejection
– Beach mode specifically tuned for saltwater environments
Each mode can be further customized through adjustable sensitivity, discrimination, and notch settings, allowing users to fine-tune the detector’s performance based on specific hunting conditions.
Iron Volume Control
One standout feature is the iron volume control, which allows users to adjust how the detector responds to iron targets. This is particularly useful in areas with heavy iron contamination, as it helps distinguish between valuable targets and unwanted iron debris. The iron audio feature provides additional information about target composition, helping experienced users make better dig decisions.
Practical Field Performance
Depth and Target Separation
In real-world testing, the Simplex Ultra demonstrates impressive depth capabilities. Users report consistently detecting coins at depths of 8-10 inches in moderate soil conditions, with larger targets reaching depths of 12-15 inches. The detector’s advanced target separation technology allows it to distinguish between closely spaced targets, reducing the likelihood of missing valuable items hidden among trash.
Ground Balancing
The automatic ground balancing system effectively handles mineralized soils, reducing false signals and improving detection accuracy. For challenging ground conditions, manual ground balancing is also available, giving experienced users complete control over the detector’s performance.
Essential Accessories and Upgrades
Search Coils
While the standard 11-inch coil provides excellent all-around performance, several aftermarket coils can enhance specific detecting applications:
The Nel Tornado coil offers increased depth and better separation in trashy areas. The smaller 5-inch coil improves maneuverability in tight spaces and around iron targets. For maximum depth on large areas, the 15-inch coil extends detection range significantly.
Audio Options
The builtta Simplex Ultra includes both built-in speaker and wireless headphone capabilities. For serious detecting, investing in quality headphones like the Nokta Impact Pro or similar models can significantly improve target identification and reduce external noise interference.
Tips for Maximizing Performance
Proper Swing Technique
Maintain a slow, overlapping swing pattern approximately 1-2 inches above the ground. This ensures complete coverage and allows the detector’s advanced signal processing to accurately identify targets. Avoid lifting the coil at the end of each swing, as this can cause you to miss targets along the edges of your search pattern.
Ground Balancing Best Practices
For optimal performance in mineralized soil, perform ground balancing away from metal objects and in an area representative of your hunting location. If you notice persistent false signals, consider manually adjusting the ground balance rather than relying solely on automatic tracking.
Discrimination Settings
Start with moderate discrimination settings and gradually adjust based on your findings. Too much discrimination can cause you to miss valuable targets, while too little can result in excessive digging of trash. Pay attention to the audio tones and visual target ID to make informed decisions about which signals to investigate.
Common Applications and Hunting Strategies
Beach Hunting
The Simplex Ultra excels in beach environments thanks to its saltwater mode and waterproof construction. Focus on areas near towel lines, volleyball courts, and water entry points where people tend to lose items. The detector’s sensitivity to small gold jewelry makes it particularly effective for finding lost rings and chains.
Relic Hunting
For relic hunting in farm fields and wooded areas, use the Field mode with reduced sensitivity to minimize interference from large iron objects. Search along old fence lines, around building foundations, and in areas where historical activity was concentrated. The detector’s ability to handle mineralized soil makes it well-suited for these challenging environments.
Cache Hunting
When searching for caches or larger buried objects, use the All Metal mode with maximum sensitivity. Search in a grid pattern and pay special attention to areas that produce consistent, repeatable signals. The Simplex Ultra’s depth capabilities make it effective for locating buried containers and other cache-type targets.
Maintenance and Care
Cleaning and Storage
After each use, especially in saltwater environments, rinse the detector with fresh water and dry thoroughly. Store the detector in a cool, dry place away from direct sunlight. Periodically check all connections and inspect the coil for damage.
Battery Maintenance
To maximize battery life, avoid completely draining the battery before recharging. The lithium battery performs best when kept between 20% and 80% charge. If storing the detector for extended periods, maintain the battery at approximately 50% charge.
Comparison with Similar Models
Simplex+ vs. Simplex Ultra
The Ultra model offers several key improvements over the original Simplex+, including enhanced target separation, better discrimination, and improved depth detection. The Ultra also features updated firmware that provides more stable performance in challenging conditions.
Competition Analysis
Compared to similar detectors in the $300-500 price range, the Simplex Ultra offers exceptional value with its combination of advanced features, waterproof design, and user-friendly operation. While some competitors may offer slightly better performance in specific areas, the Ultra provides the best overall package for most detecting applications.
