1. Overview – Minelab and the Manticore

Minelab Electronics is an Australian manufacturer headquartered in Mawson Lakes near Adelaide that has been one of the technological pioneers in metal detecting for decades. With the Equinox, the company made simultaneous multi-frequency technology accessible to a wide audience, and with the CTX 3030 it introduced a two-dimensional target display into the hobby segment early on. The Manticore combines both lines of development and takes them to a new level: faster engine, more transmit power, revised signal processing and a much further developed 2D target display.

Internally the detector carries the model number 3228-0200. In the Minelab range, the Manticore is the top model for coin and treasure hunting; only the gold specialists GPX 6000 and GPZ 7000 rank above it in the overall hierarchy – but they are specialised purely in gold prospecting in mineralised ground. For detectorists hunting coins, jewellery and relics on historical sites, in parks, fields, on beaches and under water, the Manticore is Minelab's most technically mature detector.

4. Multi-IQ+: the multi-frequency technology in detail

Multi-IQ+ is Minelab's current generation of simultaneous multi-frequency technology and the direct further development of Multi-IQ, which was already used in the Equinox. The decisive differences from its predecessor lie in three areas: higher transmit power, a wider frequency range and completely revised digital signal processing.

More transmit power, wider spectrum

According to the manufacturer, Multi-IQ+ transmits 50 per cent more energy through the search coil than the Equinox engine, and does so over an extended frequency range. The result is higher signal strength on weak or deep targets. In practice this shows up as a cleaner, more repeatable signal response even on objects at the very limit of detectability – a difference that experienced detectorists often confirm in direct comparisons between the Manticore and Equinox 900.

Revised signal processing

The redesigned processing shows above all in target ID stability: the Manticore shows more stable target IDs for the same object across the entire width of the sweep than the Equinox. This simplifies the identification decision, especially on heavily mineralised ground or at the border between ferrous and non-ferrous. The recovery speed can be set in eight levels, allowing fine-tuning between maximum separation of closely spaced targets and the greatest sensitivity to weak signals.

Five single frequencies as an alternative

In addition to the simultaneous Multi-IQ+ mode, the single frequencies 5, 10, 15, 20 and 40 kHz are available. Low frequencies (5 kHz) are suitable for deep, large targets and ground with little mineralisation; high frequencies (20, 40 kHz) for small coins, gold jewellery and gold nuggets. Being able to switch to a single frequency when needed allows targeted adaptation to special search conditions without having to use a different detector.

5. The 2D target identification map – the unique feature

The Manticore's most striking technical feature is the two-dimensional target identification map. While conventional detectors show a detected object as a single number (target ID) on the display, the Manticore's 2D ID map shows each signal as a graphic point in a two-dimensional coordinate system.

How the 2D ID map works

The horizontal axis represents the conductivity of the detected object (0–99): on the left are poorly conductive materials such as small iron parts or aluminium foil, on the right highly conductive materials such as silver or copper. The vertical axis shows the ferrous value of the signal. Non-ferrous targets appear along the centre line or below it; iron moves upwards. Small iron parts show at the top, larger ferrous objects further down.

Every detected signal leaves a trace – a dot or a mark – whose brightness and size depend on the signal strength. Signal strength, size and depth of the object can thus be read intuitively before the first spadeful is dug. Mixed signals, such as a non-ferrous object right next to a nail, produce characteristic trace patterns that differ from clean single targets – a real gain in information compared with the classic target ID display.

Adjustable iron limits

On the 2D map, iron limits can be set as a visual dividing line. Targets above the line are classified as iron and can be muted by discrimination; targets below are treated as non-ferrous. This dividing line can be adjusted in steps: if you want to unmask as many targets as possible, choose a high limit setting; if you want to filter iron aggressively on clean ground, set the limit lower. This gives the detectorist a level of control that goes far beyond what a simple discrimination display offers.

6. Search modes – ten customisable programs

The Manticore offers ten factory-configured search modes divided into three groups. Each mode is fully customisable: sensitivity, recovery speed, audio profile, iron limits and discrimination pattern can be saved separately for each mode. A user-configurable soft key gives direct access to a freely assignable function.

7. Audio system and headphones

The Manticore's audio system offers a depth of configuration that is usual in this class of detector, but well thought out in the details. In addition to the classic tone options (1, 2 or 5 tones), there are three basic audio modes:

Target volume, iron volume, threshold and pitch can each be adjusted separately – a flexibility that helps on heavily junk-littered sites to pick relevant signals out of the background noise. Three volume profiles (Simple, Medium, Rich) allow quick overall adjustment without touching individual parameters.

ML-105 wireless headphones

The supplied ML-105 transmits audio via Minelab's proprietary low-latency wireless protocol. According to user experience, the latency is noticeably lower than standard Bluetooth, which matters when swinging fast. The headphones are light and comfortable to wear, but not waterproof – for underwater use you have to switch to the handle vibration or wired headphones via the 3.5 mm socket.

8. Search coils – M11 and the optional coil range

The Manticore comes with the M11 double-D search coil (28 cm, round). It is fully waterproof (IP68) to 5 m, has its own light and is considered a well-balanced all-round coil for most applications. Minelab offers two optional coils that extend the range of applications:

9. Ergonomics, shaft and build quality

With a total weight of approx. 1.3 kg, the Manticore is mid-field in the high-end segment. The three-piece carbon fibre shaft is compact, stable and extends from 63 cm to 144 cm. The adjustable armrest and ergonomically shaped grip provide a comfortable hold even on long outings.

The Manticore's large colour LCD panel is one of the most legible displays in the comparison field. Minelab has balanced size, contrast and information density well: target ID, 2D ID map, search mode, sensitivity, battery level and status symbols can be read without familiarisation. The display brightness can be adjusted manually in ten levels or set to adapt automatically to the surroundings.

Further comfort features in the field: a built-in flashlight on the control unit for working at dusk or in dark trenches, a backlit keypad and the handle vibration already mentioned. Charging is via a magnetic connector that clicks into place without precise alignment – a small but practical detail in everyday use.

One point occasionally mentioned in user reports: the cable between control unit and search coil runs along the outside of the shaft – not inside as on the CTX 3030. This is a design decision that reduces weight, but is occasionally found annoying on the shaft. In practice it is a marginal issue that does not noticeably affect everyday searching.

10. In the field – strengths and limitations

11. Market positioning

At 1,999 euros, the Minelab Manticore is the most expensive detector in the direct comparison field for coin and treasure hunting. Its closest in-house competitor, the Minelab Equinox 900, costs around 500 euros less and also offers simultaneous multi-frequency, but without the 2D ID map and with lower transmit power. The difference is real and clearly noticeable in demanding situations – mineralised ground, densely populated sites, heavily junk-littered areas.

Compared with the XP DEUS II (from approx. EUR 1,300–1,600 depending on configuration), the Manticore positions itself with its 2D ID map and larger display as the alternative with more visual information; the DEUS II scores with its fully wireless system, more extensive coil range, much lighter weight and true stereo audio system. Both are on a similar technical level – the preference depends on whether you value visual target information (Manticore) or audible depth and maximum freedom of movement (DEUS II).

Compared with the Nokta Legend 2 (EUR 1,099), the Manticore offers 2D target identification, higher transmit power and the more mature coil range – the Legend 2, on the other hand, is cheaper, lighter, comes with two search coils as standard and allows wireless firmware updates. For many detectorists, the price difference of 900 euros will be the decisive question.

13. Conclusion

The Minelab Manticore is the most powerful simultaneous multi-frequency detector Minelab has ever built for coin and treasure hunting. The combination of the further developed Multi-IQ+ engine and the 2D target identification map results in a system that no other manufacturer has implemented so consistently in this form. If you work on heavily junk-littered sites, hunt weak signals on mineralised ground or simply want the maximum visual information before digging, the Manticore is the most technically mature instrument on the market.

The factory settings are tuned so well that the Manticore delivers good results right from the start, even for detectorists without in-depth experience. That cannot be taken for granted for a professional detector of this complexity. Those who then explore the settings step by step – iron limits, audio configuration, interpreting the 2D map – will find that the learning curve pays off continuously in the long run.

The price of 1,999 euros is the only real limitation: it is higher than the XP DEUS II in many configurations and almost twice that of the Nokta Legend 2. If you can and want to invest this amount, you get the most technically sophisticated high-performance all-rounder in the coin hunting segment. If you are looking for a functionally strong multi-frequency detector with very good value for money, the Equinox 900, Legend 2 or DEUS II will also serve you excellently.
