XP XTREM Hunter Deep Seeking Metal Detector with Deus II Remote

The XP XTREM Hunter is a two-box deep seeking metal detector that runs on the XP Deus II wireless platform. Two coils on a 1.20 m (3.94 ft) frame use XP's Fast Multi Frequency (FMF) technology to find large buried metal, and XP gives a maximum depth of up to 5 m (16 ft). This pack is ready to use: it includes the XTREM Hunter coils and stem, a Deus II remote control, WSA II XL wireless headphones and the XP hard case. It suits cache hunters, relic hunters after large iron and anyone tracing buried tanks or metal pipes. It is not a coin or jewelry detector.

Who the XP XTREM Hunter Is For

Choose the XTREM Hunter if your targets are large and deep: a buried strongbox or metal container cache, a plow part, an anchor, a tank, a run of metal pipe. The larger the target, the better. XP built it to ignore the small shallow metal that fills most sites, so you can walk a field and hear only the big targets.

A different detector is the better choice if:

• You hunt coins, rings or small relics. XP says the XTREM Hunter is highly insensitive to small surface targets. A Deus II with a standard coil is the tool for that work, and the remote control in this pack can run one.
• You want to find gold nuggets. Nuggets are small targets, so the XTREM Hunter will pass over them. It will respond to gold only when the gold is part of a large mass of metal, such as a cache.
• You need a picture of what is underground. The XTREM Hunter shows a signal trace, not an image. The 3D ground scanners in our deep seeking metal detectors collection are a different class of instrument for that job.
• You work next to houses, power lines or industrial sites. XP recommends keeping a safe distance from all three, because they are sources of electromagnetic interference.

Why Deep Seekers Choose the XTREM Hunter: Key Features in Use

• Depth of up to 5 m (16 ft): this is XP's maximum figure. Real depth depends on the size of the target and on the ground. XP's own signal examples in the manual use a 30 cm (12 in) target at 30, 60 and 120 cm (12, 24 and 48 in), which is a useful guide to everyday use.
• Fast Multi Frequency (FMF): the XTREM Hunter works on several frequencies at the same time. XP says this gives minimal ground noise and a unique ability to limit ground effects, which is what keeps a two-box detector quiet enough to hear a deep target.
• Naturally blind to small metal: XP states that the XTREM Hunter naturally ignores small ferrous objects such as nails and bottle caps. XP puts this down to the coil geometry and the shape of its field. It is a trait of the design, not a setting.
• Iron rejection on large targets (IAR): Iron Amplitude Rejection has 5 levels plus OFF. XP describes level 3 as rejecting shallow ferrous targets and level 5 as rejecting shallow and deeper ferrous targets. XP says this discriminates some moderate-sized ferrous objects. It is off by default.
• One operator, 2.9 kg (6.4 lb): that is XP's weight for the XTREM Hunter with the remote control. The handle and support adjust, and the frame carries on an included strap.
• Fully wireless: the front coil holds the transmitter and the battery, and it talks to the remote control and headphones over XP's own radio link. There is no cable from the coils to your hands or head.
• 4-second signal recording: the remote control shows the last 4 seconds of signal as a moving graph. Press Play/Pause to freeze it and study a target.
• More than 10 hours per charge: one 18650 lithium-ion cell powers the coils. XP gives a charge time of about 4 hours with a USB charger of at least 1 A.

What's Included with the XP XTREM Hunter

• XTR115TX front coil with wireless transmitter and battery
• XTR115RX FMF back coil with cable
• XTREM Hunter frame parts and XTR-STEM S-Telescopic stem with carrying strap
• Deus II remote control (RC), supplied without its case
• WSA II XL wireless headphones
• XTR-CASE115 XP hard case, rain and shock proof
• Accessory kit with USB charger, USB-C charging cable and assembly screws
• XTREM Hunter user manual and Deus II user manual

The charger is in this pack because the pack includes the Deus II remote control. The XTREM Hunter coil set sold without a remote control does not include one. Not included: a standard Deus II search coil and the stem to carry it, a pinpointer and the XP Backpack 280, which XP lists as an option. Serious Detecting does not add anything to this listing.

Warranty: XP gives a 5-year warranty on parts and labor. Batteries and connectors carry a 2-year warranty.

Pairing and the Dedicated XTREM Hunter Menu

You pair the XTREM Hunter with the remote control as a new coil, by entering its serial number under Option, Pairing, Coil. The remote control then switches to a dedicated interface with settings made for wide and deep targets. XP's manual asks for remote control software version 2.0 or higher.

• Sensitivity: 0 to 99, default 85. XP says most use falls between 70 and 90.
• Reactivity: 3 levels, default 1. Level 1 gives the most depth and helps cancel interference and small targets, and you walk slowly. Higher levels respond faster and help pinpoint a target's position.
• Discri IAR: OFF to 5, default OFF. This is the iron rejection covered above.
• Ground balance: Grab or manual, from 59 to 95. XP says the factory setting of 87 works best in most cases.

The same menu also holds Threshold (0 to 20), Auto Tune (OFF to 3), Audio Response (4 levels), Frequency Shift (14 bands, automatic scan or manual), Square or Pulse audio, a 4-band equalizer and 3 programs: 1 factory and 2 user. XP's advice is to start every session with an automatic noise cancel scan.

Reading a Target on the Screen

You judge a target from the sound and from the 4-second graph. XP explains that signal strength helps you estimate depth and signal duration helps you estimate size. In XP's examples a shallow target at about 30 cm (12 in) usually draws a double-lobe signal with a negative dip between the lobes. The same target at 60 cm (24 in) shows a strong first lobe and a weaker second one. At 120 cm (48 in) the signal is clear but quite faint.

To confirm a target, XP's method is to set Auto Tune to OFF, retune, then move slowly around the spot to find its center. Raising Reactivity speeds this up.

Where the XTREM Hunter Works Well and Where It Does Not

Caches on Farmsteads and Open Fields

You walk a grid with the frame level and hear only the large targets, because nails, bottle caps and other small trash do not register. One person can cover a field without a helper.

Limits: XP says the XTREM Hunter is highly insensitive to small surface targets, so it is not for single coins. Take off anything metallic before you start. XP lists shoes, smartphones, belt buckles and keys, and warns that most hiking gear has a wire metal frame. XP recommends sports shoes or rubber boots, checked with a pinpointer.

Large Relics and Site Survey

XP names large relics among the targets the XTREM Hunter is made for, and gives anchors, hammers and horseshoes as examples of the moderate-sized iron that IAR can reject. With IAR off you hear all large metal. With IAR on you can thin out shallow iron and keep listening for what is deeper. Freeze the graph with Play/Pause over each hit and compare the traces before you decide where to dig.

Limits: IAR discriminates some ferrous objects, not all, and XP ties the result to distance. Our how deep do metal detectors go guide explains why target size matters so much for depth.

Buried Tanks and Metal Pipes

XP lists tanks and metal pipes among the underground objects the XTREM Hunter detects. Both are large metal targets of the kind it is built to find.

Limits: it finds metal only, and it does not replace a utility locate before you dig. XP also advises keeping away from power lines, houses and industrial areas, which rules out many urban job sites. Do not test it indoors: XP says there is too much interference and metal.

Handling Ground Noise and Interference

XP credits the FMF platform with a unique ability to limit ground effects. In use, the tools are simple. Start with the automatic noise cancel scan. Leave ground balance at 87 unless you are on certain magnetic ground, where XP suggests trying a lower setting with Grab or by hand. Press retune before you walk and retune regularly as you go.

If the machine is still unstable, XP's advice is to reduce Sensitivity, reduce Reactivity and reduce Audio Response. Keep the frame horizontal. XP notes that an XTREM Hunter turned on its side at 90 degrees picks up more electromagnetic interference. Keep the handle adjusted so the coils stay far enough off the ground to avoid excess sensitivity to surface targets. The XTREM Hunter detects accurately only on its bottom side, so never pass a test target over the top of it.

Switching to Standard Deus II Coils

The remote control in this pack is a full Deus II remote control, and switching between the XTREM Hunter and a standard Deus II coil is easy because it is done on the remote control. Pair each coil once under Option, Pairing, Coil. After that you choose the coil you want in the same menu and the remote control changes to that coil's menus. XP suggests switching to standard Deus II coils to confirm targets at moderate distances and names the Relic program for the job. A standard coil and its stem are not part of this pack.

The reverse also holds. If you already own a Deus II, the XTREM Hunter coils pair with your remote control, and XP presents the XTREM Hunter as an accessory for the Deus II. This pack is for the buyer who does not have a remote control yet.

Headphones and Audio

The WSA II XL headphones in this pack are full-size wireless headphones rated IP68 to 1 m (3.3 ft). XP also lists the WSA II and WS6 as rainproof headphone options for the XTREM Hunter, along with the BH-01 bone conduction headphones. The Pulse audio type is not available with the speaker or the BH-01. More choices are in our metal detector headphones collection.

Transport, Weather and Charging

The XTREM Hunter comes apart and packs into the XTR-CASE115 hard case, which XP describes as rain and shock proof. The case measures 725 x 480 x 170 mm (about 28.5 x 18.9 x 6.7 in). The case weighs 2.7 kg (6 lb) empty and 5.8 kg (12.8 lb) packed.

XP says the waterproof construction of the XTREM Hunter can withstand rain and challenging conditions. The waterproof depth rating belongs to the remote control, which XP rates waterproof to 20 m (66 ft), IP68. We have not found an XP immersion depth for the coils.

Charge the front coil with the included charger and USB-C cable. XP gives an operating and charging temperature range of 0 to 40 C (32 to 104 F), so do not charge it in a freezing truck or a hot one. Spare straps, screw kits, charge cables and cases are in our XTREM Hunter parts and accessories collection.

How the XTREM Hunter Compares with Its Closest Alternatives

A Deus II with a standard coil: same remote control and headphones, opposite job. A standard coil finds coins, rings and small relics with target ID, at coin depths. The XTREM Hunter ignores those targets and reaches far deeper on large ones.

A traditional two-box detector: the Fisher Gemini 3 is another two-box detector we stock. The XTREM Hunter offers, on XP's figures, simultaneous multi-frequency operation, iron rejection, a signal graph and a wireless link to the remote control and headphones.

A 3D ground scanner: scanners record a survey and draw it as an image, and they sit in higher price bands. The XTREM Hunter is quicker to walk a site with and gives you audio and a live trace.
