The Invenio is the world's first real-time smart detector & Imaging system and displays top view shape, depth, dimensions and object identification of underground metals such as iron, gold, silver and even underground spaces such as tunnels, cellars, tombs, caves). The Invenio represents one of the greatest advances in metal detection technology since conventional metal detectors appeared on the market in the 1930s. Although many new features and developments in technology have been introduced since then, Invenio offers the first major step forward in the visual imaging of the metal detection process.

3-fold patented technology
After years of extensive research & development and advanced engineering studies, Nokta|Makro has achieved the development of the world's first Smart detector & Imaging System! A 3-fold patented technology from Nokta|Makro.

Easy and clear operation
Despite the many features that the Invenio offers, it is still easy to operate. The menu is structured to be clear and uncluttered making it easy to navigate through the options. The menu can be set to as many as 17 different languages, allowing it to be used all over the world. In addition, the Invenio features a Basic modes that allows you, as a beginner, to begin your search right away. The steps you need to perform for your search such as calibrating the IPTU sensor and performing ground balance are explained very user-friendly on the screen. 

IPTU SENSOR (Integrated Positional Tracking Unit)
Developed by Nokta|Makro, the IPTU unit. Using this sensor, by moving the search coil, calculations are made which are displayed directly on the screen. With the IPTU sensor, you can track the start and end point of the scanned area and view the exact locations of detected objects. In addition, you can determine the width and length of the scanned area, the depth of the object, and the shape and dimensions using the IPTU sensor.

Artificial intelligence Artificial intelligence
The Artificial Neural Network enables the device to provide superior shape extractions and depth indications using adaptive learning algorithms!

Multi deployable
There are various objects to detect with the Invenio from deep treasures at several meters depth, coins, gold, silver, jewelry, relics, underground spaces such as caves, tunnels, cellars etc. In short to everything you are looking for underground!

Excellent discrimination, notch and unmask
You can easily exclude unwanted objects from your search process. This object discrimination also works using the numbers on the object identification. For example, you can set that you do not wish to detect objects with an object identification of number 30 or lower (small iron). The Invenio will then stop signaling as soon as it detects the unwanted objects. Discrimination is often used to eliminate unwanted objects such as nails and pull rings. The Notch feature allows you to discriminate very accurately. You can also discriminate specific ID numbers e.g. No. 25 and 27 instead of an entire range (0-30). This contributes to the goal of finding more objects and less debris.

High performance and unparalleled depth
Discover large deep objects and treasures up to several meters deep that other detectors simply cannot detect!

High response and recovery speed
The Invenio excels in its response and recovery speed. This can be of great importance if there are multiple objects right next to each other and you do not want to miss a single object. Many metal detectors will indicate objects lying close together (within a few centimeters distance) as 1 object, so you will not realize that there are multiple objects, which can cause you to miss objects. With the Invenio, you will not miss a single object due to its super fast response and recovery time.

Search modes
The Invenio features 3 non-Motion search modes (Basic, Expert and underground space & anomalies) and 3 motion search modes (all metals, fast & deep)
  • The Basic mode is designed for beginners. You set the sensitivity as desired and calibrate the IPTU sensor and you can start searching. In This mode, iron is automatically discriminated and non ferrous can be searched. Suitable for quick treasure searching and analyzing the objects before they can be dug out.
  • The expert mode is designed for the advanced searcher. Should you become familiar in basic mode, you can begin experimenting in expert mode. Here you may and can adjust many settings such as threshold, discrimination and audio tones.
  • Underground & anomalies mode is designed to locate changes and anomalies in the ground as well as underground cavities such as rooms, tunnels and basements. All you need to do is this mode is just calibrate the IPTU sensor and search
  • All metal mode is recommended when you do not want to use the discrimination function. Very suitable in the country and places where there is little iron waste.
  • The fast mode is extremely suitable for searching areas where there is a lot of iron in the ground. This search mode has a fast response time that allows you to better identify close objects.
  • The Deep mode is specially designed for locating relics and other large objects where you get the maximum depth from the Invenio on larger objects.
Search coils
The Invenio comes with an INV28 waterproof DD search coil with a size of 28 x 18cm. This search coil is highly suitable for accurately locating smaller objects and for searching areas where there is a lot of debris. In addition, the INV40 waterproof DD search coil with a size of 40 x 35cm is also included in the standard package. This is an all round search coil for the Invenio with a large cover and optimal search depth. The Ivenio Pro comes further with the INV56 waterproof DD search coil measuring a whopping 56 x 49cm for even more coverage and search depth on larger objects. All Search Coils come with protective dish.
Save all your 3D scan results and screenshots and copy them to your PC. This allows you to view and analyze your scans at all times and compare them with other saved scans. You will also find tutorial videos in the archive explaining largely about the Invenio.

2.4 GHz wireless connection
The Invenio system-box and the detector communicate wirelessly d.m.v. Wifi. In addition, users can (optionally) purchase and pair the 2.4 GHz wireless headphones with the Invenio. A cable headphone is included. You are not required an internet connection for the wireless connection between the detector and the system box, but the connection between the system box and detector is a wifi connection and also a faster connection than bluetooth.

Online firmware updates
Stay up-to-date with firmware updates (via USB on PC) and get the most out of your detector

Vibration and different audio tones
If you activate vibration, the Invenio will vibrate instead of emit audio tones when detecting an object, or use vibration and audio at the same time. The vibration function is an essential feature for the deaf and hard of hearing and in noisy environments. To further distinguish metal types (iron - gold - silver etc.) the Invenio emits 3 different audio tones for the different metal types. This is a good aid to quickly recognize objects and types of metal and/or to distinguish them from each other. 

The Invenio features display lighting, key lighting and even a search coil light! In short, everything you need to get through the dark evenings in the fall. 

Invenio Standard and Invenio Pro
There are 2 versions of the Invenio available the Standard and the Pro version. 
  • The Pro version comes with an extra large 56 cm search coil with a matching carrying case that allows you to search even deeper and even faster larger areas. 
  • In addition, the Pro version features multifrequency technology with 3 search frequencies, 5khz, 14khz and 20khz ideal if your search targets are very diverse. A low search frequency is better at finding large objects even deeper, while the 20khz is more accurate at locating very small objects. The Standard Invenio comes with the usual and all-round 14khz search frequency. 
  • The Pro comes with a comfortable harness to carry the control unit with you. The stardaart version comes with a carrying strap.
  • The Pro version comes with an additional rechargeable 9500 mAh Lipo battery for the control unit.
