Invenio Metal Detector is the newest and all-new metal and gold detector that will revolutionize the world of precious metal detection and relics thanks to its new patented search technology.

The principle of this technology depends on a special search disk that scans the area to be searched with a special tracking sensor mounted on the disk arm in order to give the real shape of the buried target for such as iron nail, box or coin.

In recent years, significant progress has been made in the field of metal detector technology in terms of design and features.
but these features have not been able to meet the expectations of treasure hunters and gold prospectors.

For example, gold prospectors want the device to include features such as: Know the type of metal target discovered before digging also need to know the depth of real targets, and know the shape of buried targets and dimensions accurately … etc.

Invenio metal detector From Nokta developed in response to these expectations after many years of tests and research.

so it provides a reliable and efficient system with the first intelligent system in the world to detect buried metals then displaying a real shape of targets on screen as 3D graphics.

Invenio Metal Detector Features

Search Technology

The search coil, which is equipped with special electrical coils, transfers the power generated by the battery in the main control unit, resulting in a large-scale electromagnetic field to achieve greater search depth than traditional devices.

When an electromagnetic field collides with a buried metal object such as an old coin, a metal statue or a large box, the field signal is echoed in the form of another inverted electromagnetic field, which is received by a receiver coil within the search coil.

The data is digitally converted and the signal is processed within the main unit of the search coil unit and after the digital processing The data is transmitted wirelessly to the display unit, which has a coloured display where the data is processed and displayed as a three-dimensional diagram that displays the detailed information about the targets in the scanned area , so that the location information and the exact shape drawing depend on the tracking data The tracking unit integrated position IPTU and that transmits data wirelessly also to the screen unit.


IPTU Sensor Function
IPTU (Integrated Positional Tracking Unit) includes integrated sensors to track the movement of the search coil where the sensors record the coordinates of the coil and its height from the ground, which means recording and tracking all movements of the coil (left – right or front to back ..) accurately represent these movements directly on the unit that includes the screen visually , giving an accurate idea about coil movement within the search area.
This unit allows the prospector to determine the exact area of the search to be scanned by the search coil and the information recorded by it, contributes in knowing the positions of the buried metallic objects as well as determining the length and width of the scan area as well as the precise shape and distance of targets and the depth accurately.

Invenio Metal Detector Uses

With its unique imaging technology and the ability to detect all types of metals and even underground spaces and cavity, so the Invenio metal detector is a versatile device that can be used for a wide range of metal detection applications in the real life.

Here is a simple overview of some of the most important applications and uses of the device:

– Detecting gold and objects made of gold such as coins, old relics and ornaments such as rings and bracelets
– Prospecting for raw natural gold, which is found in shallow depths in the form of nuggets and small grains or veins in the ground.
– Detection of cavities and underground spaces such as tunnels, tombs, basements and so on.
– It can be used in municipal works such as detection of sewage pipes, telephone lines and water extensions (pipes)
– It can also be used to detect crimes and during police investigations by detecting weapons such as guns and pistols

Metal Discrimination Features
When using one of the previous search modes and after performing the scan procedure, the device displays the results on the screen unit and shows on the 3D graphics representation the type of metal based on its color. and thus, the user can know the metal type according to the color, so if the color is yellow or gradients of yellow for example it may be a precious metal, such as gold or non-precious metal if its color of red gradients.

Wireless connection between different units

Communications and data transfers between the system box of the Invenio device (the main unit with the display screen) and the coil unit (coil and shafts and IPTU) done wirelessly via Wi-Fi technology.
In addition, users who do not prefer wired headsets can purchase optional 2.4 GHz wireless headphones to hear metal targets signals when detected.

Vibration Feature
Invenio features a vibration feature. when activated, the device will vibrate when a metallic target detected.
It is an essential feature for hearing for impaired users when searching in high noise areas where there are many noise sounds.

Save Scan Data
The user can save all three-dimensional graphics and screen shots from the ground scanning then transfer it to his computer for better preview and more detailed analysis.

Device Software Update Feature
The device software updates available to download from the manufacturer’s website so the device software updated by connecting the USB cable attached to the device and downloading updates to the device.

Front LED and back light of the screen
The Invenio has a front LED lamp to search in the dark, and the screen has a back light to see the results of the scan even in the dark.

Static Search Modes

Search Modes
Invenio Metal Detector has a variety of different search modes that are suitable for specific search applications.

The search modes in the device are divided into two main categories:

1- Static Search Modes
That search mode does not require any movement of the search coil in order to obtain results at all because the device will make a sound even when the coil is above a certain object and without the need for the motion of coil.

In this case, the intensity of the sound will be close to the coil more than the close between the target and the surface of the ground.

It is recommended to use static search modes to detect metal targets of relatively large size and at more depth in comparison to dynamic search modes.

Static modes have three modes:

Basic search mode
Expert search mode
Ground Anomaly & Cavity

Dynamic Search Modes

Dynamic search modes require coil movement for performing scanning.

The user must move the search coil to the right, left, right, and backward movement in order to scan correctly.

You have to know that if the disc is not moved, the device will not produce any sound response even if the coil is directly above the metal target.

Dynamic search modes are recommended for discovering small-sized targets, like coins and small ornaments, such as rings and others, at smaller depths

Invenio has three dynamic search modes:

All Metal Mode
ast mode
Deep search mode
