Overview & manufacturer

XP Metal Detectors is a French company based in Castanet-Tolosan near Toulouse and one of the most technologically advanced detector manufacturers in Europe. XP became known for the wireless DEUS – a detector that revolutionised the segment more than a decade ago with its modular, battery-powered concept. Its successor, the DEUS II with FMF® multi-frequency technology, is also the technical basis of the XTR-115.

XP is one of the first companies to have been awarded the European Longtime® label – a certificate for sustainably designed products with guaranteed repairability for at least 10 years after the date of purchase and a 5-year manufacturer's warranty. For a professional tool in this price class, that is a relevant factor.

The XTREM Hunter XTR-115 is the brand's first deep-seeking detector and at the same time a novelty in the two-box segment: for the first time, a deep detection system combines simultaneous multi-frequency signal processing (FMF®) with complete wireless operation and seamless compatibility with a modern search detector system.

What's in the box – complete set

The complete set includes everything you need for immediate use in the field. If you already own an XP DEUS II RC, you can choose the cheaper add-on set instead.

Technical data

FMF® technology – what's behind it?

FMF stands for Fast simultaneous Multi Frequency and is a signal processing method patented by XP that transmits and evaluates 49 single frequencies between 4 and 45 kHz at the same time. Unlike conventional two-box systems, which usually work with a single low frequency, the XTR-115 constantly calculates an evaluation result from the entire frequency spectrum. This considerably reduces ground noise and allows a much quieter signal – even in heavily mineralised ground.

Technically, the XTR-115 system is paired with the DEUS II remote control via its serial number, just like an ordinary search coil. As soon as the connection is established, the display automatically switches to the XTREM Hunter's specific deep-seeking menus – with its own display values, sensitivity levels and audio programs. The system can be switched back to a normal FMF search coil in seconds, without tools and without a restart.

The iron discrimination of the XTR-115 is a real innovation in the two-box segment: until now, users of classic deep-seeking detectors had to dig blind. The XTREM Hunter can distinguish medium-sized ferrous objects from non-ferrous ones – not with the precision of a high-quality VLF detector, but well enough to rule out obvious iron finds when in doubt. The reliability of this discrimination decreases as the object mass increases, as XP itself states objectively.

No-motion operation – how is the device used?

Anyone working with a two-box locator for the first time needs some time to get used to it: the XTR-115 does not need to be swept . The device works in no-motion mode – meaning you move it slowly over the search area and hold it still briefly when a signal occurs. The signal strength increases as you approach the target object, allowing rough localisation. For precise pinpointing, it is then recommended to switch to a normal search coil and search the area in a targeted way.

The detection field builds up entirely below the two coils. Towards the user, the field is largely shielded – but when using it, make sure you are not carrying any metal objects on your body: mobile phones, keys, belt buckles, shoes with metal inserts and the like can distort the result. XP recommends checking your own equipment with a pinpointer before every search – especially outdoor shoes, which often contain a thin metal plate in the sole.

Seamless DEUS II integration – the modular system in practice

The most convincing argument for the XTR-115 is not the pure depth performance – but the way it is embedded in the XP ecosystem. Other two-box systems are stand-alone devices with a separate control unit, their own battery and their own learning curve. The XTREM Hunter, on the other hand, behaves like a large coil – with all the advantages that brings:

The wireless headphone connection runs on XP's own radio protocol – which, according to the manufacturer, is 10 times faster than Bluetooth and therefore works practically without latency. For deep-seeking detectors that transmit subtle signal changes, this is a real argument.

Areas of use

The XTR-115 is not a detector for the everyday detectorist. It was developed for situations in which large objects are searched for at great depths – and in which a normal detector simply cannot go any further.

Ergonomics & transport

With a total weight of 2.9 kg with the remote control fitted, the XTR-115 is exceptionally light for a deep-seeking detector of this class. Classic two-box systems such as the Fisher Gemini-3 or the Garrett TreasureHound are heavier, more unwieldy constructions that require body harnesses for longer use. The XTR-115 is designed for one-person operation and can be individually balanced via the adjustable handle.

The height-adjustable S telescopic shaft can be completely dismantled. Taken apart into its individual components, the entire system fits into the supplied hard-shell case (725 × 480 × 170 mm, total weight 5.8 kg). If you are often on foot, you can choose the optional XP BP280 backpack as an alternative. The assembled length of 1.2 m is adapted to average body heights, but the handle can be moved to adjust the balance for taller or shorter people.

Strengths & limitations

The XTR-115 is a very specialised device. Anyone who understands what a two-box locator can and cannot do will be very satisfied with the XTREM Hunter. Anyone looking for an all-round device is badly advised.

Available set versions at a glance

The XTREM Hunter is available in three configurations. Depending on the equipment you already have, you can get started or expand in a targeted way.

Market classification

There are few directly comparable products in the deep-seeking segment. Classic two-box systems such as the Fisher Gemini-3 or the Garrett TreasureHound EX work with analogue single-frequency technology and have neither a wireless user interface nor iron discrimination. They cost between €500 and €900, but thanks to their simpler signal processing still offer solid performance in some scenarios for newcomers to deep searching.

In the FMF multi-frequency segment, the XTR-115 is currently without competition. No other manufacturer offers a two-box deep-seeking system with simultaneous multi-frequency technology, wireless operation and true system integration into a modern search detector. Anyone who has already invested in the XP ecosystem will find the XTR-115 a logical addition that greatly enhances their own equipment.

Rating in detail

Conclusion

The XP XTREM Hunter XTR-115 closes a gap that has long existed in the deep-seeking market: a modern, light, wireless two-box system with multi-frequency technology and true system integration. What used to mean two separate devices – search detector and two-box locator – with two learning curves, two batteries and two cases has grown together with the XTR-115 into a single, handy complete set.

The advantage for existing DEUS II users is obvious: the system is paired like a new coil, the user interface remains familiar, and switching between deep searching and normal searching takes seconds. This is not just convenient – it is real practical added value in the field when you locate a first signal with the XTR-115 and then pinpoint it precisely with a small FMF coil.

Who is the XTR-115 the right choice for? For serious detectorists who regularly work in areas where conventional detectors reach their limits. For archaeologists, explosive ordnance disposal teams and treasure hunters who are after large objects lying deep. And for DEUS II owners who want to expand their existing system sensibly and without much extra effort.

Anyone looking for an entry-level detector or an all-round device for coins and jewellery, on the other hand, is badly advised – the XTR-115 is neither designed nor suitable for that.
