The Nokta Invenio Pro is an advanced smart metal detector and underground imaging system designed to provide visual information about buried targets. Using the integrated IPTU sensor, it can display the estimated shape, depth and dimensions of underground metals while also detecting ground anomalies and cavities.
Ideal for:
The Invenio Pro features 5, 14 and 20 kHz VLF operation, six search modes, 00 to 99 Target ID, a 7-inch colour display, IPTU tracking sensor and three waterproof DD search coils.

The Nokta Invenio Pro price is £5,999.95 with free UK delivery. It sits at the top of the Nokta range by a long way, and it answers a question no coil detector can: not just whether something is there, but roughly what shape it is and how deep. If you are comparing it against an underground imaging metal detector or a ground scanner, read the honest comparison below before you spend.

The Nokta Invenio Pro is an advanced smart metal detector and underground imaging system designed to provide more information than conventional metal detectors. Using its integrated IPTU (Integrated Positional Tracking Unit) sensor, the Invenio Pro can display the estimated shape, depth and dimensions of underground metal targets, while also identifying ground anomalies and cavities.
The Invenio Pro is designed to go beyond basic audio signals and Target ID numbers. Its imaging system provides visual information about detected targets, including their shape, depth and dimensions, helping users analyse underground targets before deciding whether to dig.
The integrated IPTU sensor tracks the movement and position of the search coil during scanning. This allows the system to record the scanned area and display the location, depth, shape and dimensions of detected targets.
The Invenio Pro is designed for detecting deep treasures, caches, coins and relics, as well as ground anomalies and cavities such as potential underground caves and tunnels. It provides dedicated scanning modes for both metal detection and ground-anomaly detection.
The detector offers three non-motion modes, Basic, Expert and Ground Anomaly & Cavity, along with three motion modes: All Metal, Fast and Deep. This provides flexibility for different detecting and scanning applications.
The Invenio Pro operates using 5 kHz, 14 kHz and 20 kHz frequencies and provides automatic, manual and tracking ground balance. It also includes 00 to 99 Target ID, 01 to 99 sensitivity adjustment, Iron Audio, Tone Break, Notch Filter, Pinpoint and Frequency Shift.
The system features a 7-inch 800 × 480 RGB TFT display for viewing detection and imaging information. Screen backlighting and a built-in LED flashlight also allow the Invenio Pro to be used in low-light conditions.

If your budget is the deciding factor, be clear eyed. At £5,999.95 this costs more than seven Simplex ULTRAs. For finding coins and relics on British permissions it will not find seven times more.
If what you need is depth rather than imaging, a ground scanner such as the Groundtech GR-4 at £1,750 reads far deeper for far less, although it cannot tell you whether the anomaly is metal.
If you are new to detecting, this is the wrong first machine by a wide margin. The imaging only means something once you already know how ordinary detector signals behave.
£5,999.95. It is by some distance the dearest Nokta we stock, because it is a detector and an imaging system rather than a detector alone. See the rest of the range on our Nokta page.
The estimated shape, depth and dimensions of a buried target, rather than a tone and a number. Knowing that something is coin shaped at eight inches against box shaped at three feet changes whether you dig it, and that is what you are paying for.
The Integrated Positional Tracking Unit. It tracks where the search coil moves during a scan, which is what lets the system build a map of the area rather than report isolated signals. Without position tracking there is no image.
Yes, it detects ground anomalies and cavities such as potential caves and tunnels, with dedicated scanning modes for that separately from metal detection. That makes it genuinely useful for archaeology rather than only for treasure.
Three non motion modes, Basic, Expert and Ground Anomaly and Cavity, plus three motion modes. Having both families on one machine is unusual and is the reason it can sweep ground and then assess a target properly.
5, 14 and 20kHz VLF, with 00 to 99 Target ID and a 7 inch colour display. The display size matters more than it sounds, because you are reading images in daylight rather than glancing at a number.
A scanner such as the Groundtech GR-4 at £1,750 surveys deep ground but will not find coins. The Invenio Pro works as a normal detector and images what it finds. Different jobs, and the Invenio is the one you can still hunt with.
Someone doing serious cache, treasure or archaeological work who wants imaging without carrying two instruments. For ordinary coin and relic hunting it is a great deal of money, and the Legend at £799.95 will find the same coins.
For most detectorists, no, and we would rather say so. It earns its price for people doing archaeological or professional survey work where knowing the shape and depth before digging matters. For weekend coin and relic hunting, the money goes further elsewhere in the range.
It is an estimate built from how the signal changes as the coil moves, not a photograph. It is good enough to distinguish a large flat object from a small round one and to give you a depth to work to. Treat it as information, not certainty.
It detects ground anomalies, which includes cavities with no metal in them. How well depends entirely on soil, size and depth, as it does with any instrument of this kind.
Three waterproof DD search coils, the IPTU sensor and the 7 inch colour display unit, with 2.4 GHz wireless communication and online firmware updates.
If you want one machine that both detects metal and gives you a picture at coil depth, the Invenio Pro. If you want to survey a large site metres down and will carry a separate detector to confirm finds, a ground scanner costs less and reads deeper. Ring us and describe the site.
