Overview
THE BEGINNING OF A NEW ERA IN METAL DETECTOR TECHNOLOGIES! GO BEYOND BEEPS AND NUMBERS

Invenio is the first and only revolutionary step taken in the realization of a dream in the metal detector sector. Since the emergence of classic metal detectors in the 1930s, metal detectors have managed to offer many new features in parallel with the developments in technology, but they have not been able to fully meet the expectations of users. When you look at it, other competitor companies in the sector have signed many patents in metal detector technologies for years, but even today they have not been able to go beyond giving an audible warning to the target and distinguishing metals with target ID numbers, and they have been stuck at similar points.
However, until today, users have always expected more from a detector:
1. To discover deeper targets
2. To know what type of metal the detected target is
3. The actual depth of the targets
4. To see the shapes or forms of the targets
5. To determine the dimensions of the targets
6. To find ground differences/cavities.
Nokta Detector has been taking steps to make this dream of its users come true since the day it was founded, and as a result of many years of intensive R&D and high engineering studies, it has managed to develop the world’s first smart detector and imaging system Invenio, whose entire technology belongs to itself and for which 3 separate patent applications have been made, and today it proudly presents it to its users.
Invenio is designed as an open platform for development and is intended to be applied to all hobby detectors (coin and foundry detectors) as well as gold detectors that detect natural gold particles in the future.
THE WORLD’S FIRST REAL-TIME SMART DETECTOR AND IMAGING SYSTEM THAT CAN DISCRIMINATE AND SHOW THE SHAPES, DEPTH AND SIZES OF METALS AND GROUND DIFFERENCES/CAVITS UNDER THE GROUND
IPTU SENSOR (Integrated Positional Tracking Unit)
Developed by Nokta & Makro Detector, the IPTU unit is used to precisely calculate the right-left, forward-backward movements of the coil with the help of the sensors inside, and to determine its position and height above the ground. With the IPTU sensor, you can track the start and end points of the area you scan on the screen and see the positions of the targets you detect on this area. In addition, with the help of the IPTU sensor, you can also determine the width and length of the area you scan, the estimated depth, shape and dimensions of the detected target.
SEARCH AND RESULT SCREENS
Real Field Underground Testing
- Learning with Artificial Intelligence: Artificial Neural Network uses adaptive learning algorithms, allowing the device to extract much better shapes and provide depth information!
- Multi-Purpose: Targets you can find with Invenio: Great treasures deep down, single coins, ancient artifacts made of metal, ground differences / underground spaces such as caves and tunnels… In short, everything you are looking for underground!
- High Performance and Unmatched Depth: Discover the deep treasures that other detectors cannot detect.
- 3 Static Search Modes: Basic / Expert / Ground Anomaly & Void.
3 Dynamic Search Modes: All Metal / Fast / Deep
- 17 Languages: English / German / Greek / Turkish / French / Italian / Russian / Arabic / Spanish / Chinese / Persian / Bulgarian / Serbian / Romanian / Dutch / Portuguese / Polish
- Internet Software Update: Get the best performance by keeping your detector always up to date (via USB connection via PC).
- 2.4GHz Wireless Connection: Invenio system box and search handle communicate wirelessly. Also, users who do not prefer wired headset can purchase 2.4GHz wireless headset sold separately.
- Vibration: When this feature is active, Invenio gives a vibration alert when it detects a target. It is an indispensable feature for hearing impaired users and high noise environments.
- Excellent Discrimination Ability: Find only the targets you are looking for and don’t waste time digging for unwanted metals.
- Very High Metal Detection Speed: Get ready to find what other detectors miss among iron and trash!
- LED Light and Screen Illumination: Thanks to Invenio’s screen illumination and LED light that illuminates the area you are searching in, you can search in the dark.
- Archive: You can save all 3D graphics and screenshots and transfer them to your PC if you wish.
