XP Deus 2 – Questions and Answers

Has the depth of the new multi-frequency XP Deus 2 with FMF technology increased?

1. The Deus 2 can detect small targets (low conductivity targets) that a conventional single frequency metal detector (4 or 7 kHz) will not detect, especially if the ground is mineralized. To check this, take a low-conductive target (scales, for example, with VDI indicators of 30-35), these targets will be quickly missed by detectors operating at low frequencies, even in not very mineralized soil, but they will be better detected by a multi-frequency metal detector.
2. Alternatively, low frequencies may detect large objects or groups of coins that high frequency detectors (20-80 kHz) may have difficulty detecting or not detect at all. While searching, of course, such stacks of coins are not a common target, but to check this, simply pick up a stack of non-ferrous coins. You will see that multi-frequency programs will see such a stack of coins as a good target (colored). At the same time, high frequencies such as 20-80 kHz will discriminate against these targets or identify them as a ferrous target, depending on the position of the stack of coins in front of the coil. Such targets are defined as high-frequency ground and cannot be fully detected by single-frequency detectors unless the discrimination is reduced to accept the ground.
3. On electrically conductive ground, such as salty beaches and surf zones, FMF technology will not operate as unstable as single frequency metal detectors, and at the same time, FMF will detect targets deeper and with better stability. At the same time, especially in wet soil, single frequency metal detectors can emit a large halo effect, which may indicate the presence of a large and deep object, since the problem is precisely the conductivity of the wet soil. In FMF technology, using Deus 2 in Program 1 or Relics, cutting off the influence of the ground can remove the Halo effect, allowing you to focus on truly deep useful targets.
4. In most situations, multi-frequency programs provide more correct identification of an object at depth (more stable VDI), as well as sound identification, which is much closer to reality and has less interference than in the case of a single-frequency metal detector. In All Tones (Polyphony) mode, tones are also less distorted. This is even more noticeable on small targets at depth, when single-frequency metal detectors begin to transmit incorrect information to the user (different color tones – black, “jumping VDI”, etc.).
5. FMF technology makes it even easier to identify unwanted targets. For example, Bcap reject mode makes it possible to reject iron caps without affecting useful targets. Also, you may notice the ability to accurately cut “notch” conductive rocks (coal and others), or freshly dug holes and ground changes such as wet ground that can create interference or a halo effect. (Cutting levels 23-25).

What frequencies are used in multi-frequency mode?

The XP Deus 2 metal detector has a transmitter capable of transmitting many frequencies simultaneously. Depending on the search program, the most suitable ones are demodulated (multi-demodulation) in order to combine them to achieve the best results. The Deus 2, unlike other multi-frequency metal detectors that typically offer one set of frequencies that cannot be changed in multi-frequency mode, includes actual combinations of different frequencies in its detecting programs. For example, some programs only use low and mid frequencies at the same time: 4-14 kHz, while other programs may include higher frequencies, like 24 kHz and higher up to 40 kHz. For these frequency combinations, special signal processing is applied to better adapt the metal detector to the ground. Such a set of frequencies can completely neutralize (remove) the influence of highly conductive soils and add a wide range of detected targets if the soil is not too wet. In the “Programs” section of the instructions for Deus 2 you will find the entire selection of frequencies available for a particular program. Since the Deus 2 is software upgradeable, the frequencies used and their combinations may change in future updates.

In a single-frequency program (Deus Mono, program number 7), you can choose one of 7 main search frequencies: 4.5-7.5-13-17.6-25-32-40.5 kHz, each of which has 7 shift options, that is, about 49 frequencies together! The frequency level is as follows: 4.08 – 4.76 kHz, 6.94-8.08 kHz, 20.39-15.15 kHz, 15.62-20.75 kHz, 22.06-28.57 kHz, 29.41-35.32 kHz, 36.36-45.45 kHz.

What does Fast Multi-Frequency (FMF) actually mean?

Deus 2 uses simultaneous frequencies (transmitting and demodulating simultaneously) combined with fast audio response, with extremely short latency. You will not notice any difference in operating speed compared to the Deus 1.

Why is the sound transmission of Deus 2 faster than the so-called “low latency” Bluetooth technology?

Deus II, Deus and ORX use patented radio audio transmission technology. This protocol from XP is not standard; it was developed specifically for metal detecting, since Bluetooth technology has a fairly large delay for the technologies and protocols we use for audio transmission and sound dynamics (100 mS). Even if some people talk about “low latency”, this is still quite a lot of audio latency for metal detecting, about 40ms slower.

Therefore, our patented transmission is approximately 10 times faster. For example, when you swing the coil approximately 2 meters per second (swing amplitude), a difference of 40 milliseconds amounts to a delay of 8 centimeters for the search zone in one direction + 8 centimeters in the other, amounting to a total delay “distance” of 16 cm, which will result in to problems with determining the location of the find, for us this is simply unacceptable. Moreover, if you're digging in a trashy area, you simply won't be able to identify targets quickly and will spend quite a lot of time locating the location, time that you could be spending searching for new targets.

Are headphones from XP unique?

Our wireless headphones are not something purchased from third-party headphone manufacturers, they are completely our unique design and the headphones are made in France by us, XP. They are updatable via USB, their volume and equalizers are controlled via a control unit (Deus 2), they turn on and off themselves without any intervention from you, moreover, they work for quite a long time on a single charge (15-17 hours).

WS6, WSA and WSA II are waterproof, and the WSA II-XL can be submerged in water up to 1 meter deep. BH-01 allows you to dive to a depth of 20 m (bone conduction headphones). If you add to this an audio latency of 4 ms instead of 40-100 ms for Bluetooth and a 5 year warranty, then you will quickly understand why similar products cannot be found anywhere else. All these little additions make the Deus 2 a better product, attention to detail is our goal.

What is the best search coil for beach searching?

We recommend using the 28cm reel, it provides better ground coverage and a good compromise between weight/performance/stability on a wet salty beach where iron trash targets are fairly scarce.

Why are 2 plugs used to waterproof the control box?

The advantage of the XP Deus 2 metal detector over other waterproof detectors is that when deeply immersed in water, the XP Deus 2 has a fairly loud speaker and convenient buttons that are easy to use during land searching. Typically, deep dive detectors do not have a loud speaker – the standard is to use potentiometers or large buttons that are not affected by water pressure at depth, or are deformed by changes in temperature and atmospheric pressure. The seals must be balanced for land search to prevent blocking the speaker diaphragm or damaging the control buttons. In principle, conventional submersible detectors at depths of 1 to 3 meters use microporous membranes that allow air to pass through while keeping water out (at depths of up to 3 meters this is possible). Since the XP Deus 2 can dive deeper than 1-3 meters, we offer the option of locking the membrane during deep diving using the red cap. Therefore, please do not look at this as a disadvantage, but rather as an advantage and the ability to combine the operation of the speaker and control buttons during a deep dive. If you primarily search on land, in lakes or streams, or in the surf zone of the sea, you will probably never need a red cap.

Gray cap number 1 – 1 meter maximum immersion depth.

This plug is needed mainly for constant search on the ground or when the control unit is immersed to a depth of up to 1 meter. It helps balance internal pressure to prevent damage to the control unit from damage during temperature and pressure changes. The waterproof membrane allows air to pass through, and at the same time it does not allow water to pass through at depths of up to 1 meter.

Red cap number 2 – 20 m maximum immersion.

For underwater use only! On the ground, the red cap will not be able to balance the internal pressure, which may damage the speaker or control buttons in the control unit during temperature changes. If this happens to you, then you need to insert the gray cap and bleed off the pressure inside the block – just bring it to your lips and bleed out the hole. Before diving to depths greater than 1 meter, install the red cap (number 2). The maximum diving depth is 20 meters. Rinse the metal detector with running water after searching, wipe with a dry towel and then install the gray cover (number 1) for use on land or at depths up to 1 meter.

Will there be changes in version 1.0 for Deus 2?

Please understand that Deus 2 is a completely new electronic platform with completely new software that may undergo many new developments and changes. Just like Deus 1 when it was released in version 1.0, it has gone through enough updates up to the current version 5.21 that Deus 2 will soon receive its software update.
