Gold Hunter T90 Metal Detector Waterproof Underground Gold Detector With Wireless Headphones

The Gold Hunter T90 is a high-performance, versatile underground metal detector designed for treasure hunters, prospectors, and hobbyists seeking to locate metallic objects, including gold, coins, relics, and other buried treasures. With advanced technology, a fully waterproof design, and user-friendly features, the T90 is suitable for both beginners and experienced users in diverse environments, from dry land to shallow water. Its robust construction, precise detection capabilities, and ergonomic design make it an excellent choice for detecting metal in highly mineralized soils, beaches, and other challenging terrains. Core Functionality The T90 uses electromagnetic induction to detect the presence of metal objects underground or hidden within other materials. It is equipped with a sensor probe (search coil) that is swept over the ground to detect metal. The device provides real-time feedback through visual, auditory, and numeric indicators, with stronger signals indicating closer proximity to the target. The T90 excels at distinguishing between different types of metals, reducing false positives, and providing precise target location, making it ideal for prospecting natural gold, coins, jewelry, and other metallic objects.

Detailed Features

1. Metal Differentiation and Discrimination:
   • Numeric, Sound, and Cursor Indicators: The T90 employs a multi-modal detection system that displays different values, produces distinct audio tones, and shows unique cursor movements for various metals (e.g., ferrous vs. non-ferrous). This allows users to identify the type of metal before digging, minimizing unnecessary excavation.
   • Ferrous/Non-Ferrous Distinction: The detector can differentiate between iron-based (ferrous) metals and valuable non-ferrous metals like gold, silver, and copper, which is particularly useful for gold prospecting in mineral-rich environments.
2. Intelligent Backlight System:
   • The T90 features an adjustable backlight on its 59 x 53 mm LCD screen, which can be toggled on or off based on ambient lighting conditions. This ensures clear visibility in low-light environments, such as during nighttime treasure hunting or in shaded areas.
3. Automatic Ground Balance:
   • The T90 includes an automatic ground balance function that adapts to complex soil conditions, such as highly mineralized or salty environments. This feature minimizes false signals caused by ground mineralization, ensuring accurate detection without constant recalibration. For gold prospecting, this is critical, as gold is often found in mineralized rocks where manual balancing would otherwise be necessary.
4. Precise Positioning:
   • A dedicated positioning button allows for quick and accurate pinpointing of targets. Unlike other detectors that require prolonged button pressing, the T90’s one-touch positioning simplifies the process, improving efficiency during fieldwork.
5. Fully Waterproof Design:
   • The entire unit, including the control unit, LCD screen, and search coil, is waterproof and can be submerged in water up to 1.3 meters deep. This makes the T90 suitable for detecting in shallow streams, rivers, or beaches, expanding its usability beyond terrestrial environments.
6. High Performance and Stability:
   • Fast Recovery Speed: The T90’s rapid recovery speed allows it to distinguish valuable targets from nearby junk metals, making it ideal for cluttered sites with mixed debris.
   • Dual Operating Modes:
     • Automatic Mode: Simplifies detection for beginners by automatically adjusting settings for general treasure hunting.
     • Sizing Mode: Provides precise target sizing and depth estimation, catering to advanced users seeking detailed information.
   • Anti-Interference Technology: Upgraded to handle high-pressure environments and resist electromagnetic interference, ensuring stable performance in challenging conditions.
7. Search Coil Options:
   • Standard 13-Inch Double-D Coil: Offers a wider detection range and deeper penetration, ideal for open fields and larger targets.
   • Optional 11-Inch Coil: Provides greater maneuverability and sensitivity for smaller targets or confined spaces. Only one coil is included per package, allowing users to choose based on their needs.
8. Wireless Headphones:
   • The T90 comes with wireless backphone headphones, providing clear audio feedback without the hassle of wired connections, enhancing mobility and comfort during extended use.

Applications
The Gold Hunter T90 is designed for a wide range of metal detecting activities, including:

• Gold Prospecting:
  • The T90 is highly effective for detecting natural gold nuggets and fine gold particles in highly mineralized soils. Gold often exists in fragmented forms mixed with sands, sediments, and heavy metal ores, producing weaker and broader signals compared to pure metals. The T90’s ability to adjust for ground balance ensures accurate detection in these conditions.
  • Ideal for gold-rich sedimentary sands and mineral deposits, including native gold, silver, and other precious metals.
• Coin and Relic Hunting:
  • The T90 excels at detecting coins, jewelry, and historical relics buried underground. Its discrimination capabilities help users focus on valuable non-ferrous metals while ignoring iron-based junk.
• Treasure Hunting in Diverse Environments:
  • Suitable for use in fields, beaches, forests, and shallow water bodies due to its waterproof design and robust anti-interference technology.
• Archaeological Exploration:
  • The T90’s precise positioning and sizing modes make it a valuable tool for amateur archaeologists seeking to locate and identify buried artifacts.

Detection Performance
The T90’s detection capabilities have been tested both in controlled (air) and field conditions, demonstrating its versatility:

• In-Air Tests:
  • 25mm Coin: Detected at 33–35 cm.
  • Red Bull Can: Detected at 65–70 cm.
• Field Tests:
  • 5g Gold Bracelet: Detected at 33 cm.
  • 25mm Coin: Detected at 27 cm.
  • Iron Sheet: Shielded (indicating effective discrimination).
• Maximum Detection Depth: Capable of detecting a 50 x 50 x 2.1 cm aluminum board at significant depth, with larger objects yielding greater detection distances.
• Note: Detection distances in the field are typically shorter than in air due to soil conditions, mineralization, and other environmental factors. Larger objects generally allow for deeper detection.
