Nokta Invenio Pro 3D Ground Scanner & Metal Detector
The Nokta Invenio Pro is a real-time smart metal detector and imaging system designed to provide detailed information about underground metals and ground anomalies. The system can display the shape, depth, dimensions and discrimination of detected underground metals, as well as detect and visualize ground anomalies and cavities.
Invenio combines Nokta's IPTU Sensor (Integrated Positional Tracking Unit), Artificial Neural Network technology and real-time imaging with six search modes. It is designed for detecting deep treasures, caches, coins, gold, silver, jewelry, relics and underground cavities such as caves, tunnels and cellars.
The Pro version operates at 5 kHz, 14 kHz and 20 kHz and includes three waterproof DD search coils — INV28, INV40 and INV56 — providing different options for smaller targets, general searching and larger objects at greater depths.
The IPTU Sensor (Integrated Positional Tracking Unit) was developed by Nokta to precisely calculate the right-left and forward-back movements of the search coil and determine its position and height above the ground.
During scanning, the user can follow the starting and finishing points of the scanned area and view the positions of detected targets. The IPTU Sensor also helps determine:
- Width and length of the scanned area
- Target location
- Target depth
- Target shape
- Target dimensions
The Invenio provides real-time imaging of underground metals and ground anomalies, giving the user significantly more information than conventional target ID numbers and audio signals alone.
The Invenio uses an Artificial Neural Network with adaptive learning algorithms to provide advanced shape extraction and depth indications.
Detected targets can be analyzed for:
- Shape
- Depth
- Dimensions
- Metal discrimination
- Position within the scanned area
The system is designed to detect everything from deep treasures and caches to coins, relics, gold and underground cavities.
The Invenio provides three Non-Motion search modes:
Basic Mode
Basic Mode is designed for beginners. The user adjusts the sensitivity, calibrates the IPTU Sensor and can begin searching.
In this mode, iron is automatically discriminated, allowing the user to search for non-ferrous metals. It is suitable for quick treasure searching and analyzing detected objects before excavation.
Expert Mode
Expert Mode is designed for advanced users and provides access to additional settings such as threshold, discrimination and audio tones.
It gives experienced users greater control over the detector's search parameters.
Ground Anomaly & Cavity Mode
This mode is specifically designed for locating ground changes, anomalies and underground cavities, including:
- Rooms
- Tunnels
- Cellars
- Other underground spaces
The user calibrates the IPTU Sensor and performs the search to locate anomalies and cavities below the ground.
In addition to the three Non-Motion modes, the Invenio provides three Motion search modes:
All Metal Mode
All Metal Mode is recommended when the user does not want to use discrimination. It is particularly suitable for searching on land and in locations containing relatively little iron trash.
Fast Mode
Fast Mode is designed especially for areas containing large amounts of iron.
Its fast response speed helps identify targets located close to one another, improving target separation in iron-contaminated areas.
Deep Mode
Deep Mode is specifically designed for detecting relics and other large objects and allows the user to utilize the Invenio's maximum depth performance for larger targets.
The Invenio Pro is designed to detect deep targets and provides detailed information about detected underground objects. The system can display the target depth, shape and dimensions and provides discrimination information for detected metals.
The device also features Target ID from 00–99, Iron Audio, Tone Break, Notch Filter and advanced discrimination and unmasking capabilities.
The Invenio Pro operates at three frequencies:
- 5 kHz
- 14 kHz
- 20 kHz
The Pro Package includes three waterproof DD search coils:
INV28 – 28 × 18 cm / 11 × 7 in
Designed for precise searching for smaller targets and for searching in areas containing large amounts of trash.INV40 – 40 × 35 cm / 15.5 × 14 in
An all-round search coil providing wide ground coverage and search depth.INV56 – 56 × 49 cm / 22 × 19 in
Included with the Pro version for even greater coverage and search depth on larger objects.Ground Balance, Sensitivity & Fast Recovery
The Invenio Pro offers three ground balance options: Automatic, Manual and Tracking.
Sensitivity can be adjusted from 01–99, allowing the detector to be configured for different search conditions.
The system also features fast recovery speed, helping detect targets located amongst trash and iron.
The Invenio system box and detector communicate wirelessly. Optional 2.4 GHz wireless headphones can also be used, while wired KOSS headphones are included in the Pro Package.
The Archive function allows users to save 3D graphs and screenshots and transfer them to a PC for viewing, analysis and comparison.
The Invenio also supports firmware updates via USB, allowing the system software to be updated through a PC.
