Accessories of eXp 4000

GPR antennas (25cm, 50cm, 75cm, 100cm) 

Scan the underground and get a 3d image!

These horizontal gpr antennas can be used for ground scanning in different areas to locate metals, voids or water. They has to be connected to the metal detector main unit and are used in the Ground Scan mode to receive a 3d image of the underground. The gpr probes are available in different sizes which optimize scanning in different conditions. The gpr antenna 25cm is specially interesting for searchers who have to scan areas with difficult access like for example in the mountains or in the jungle, where are many bushes, stones or trees. This smallest antenna can be used for a detailed research and mostly used to detect small objects like gold or silver coins, rings, gold nuggets etc. The scanning process is longer because of the small sized antenna and the small area it covers, but very suitable to search in difficult terrain. This probe is included in the basic package of eXp 4000. 

The gpr antenna 50cm is a compact scan probe suitable for nearly all measurement procedures. The larger gpr antennas with a length of 75 and 100 cm are used to scan large areas and flat ground, to get a fast overview about the complete terrain.

DDV system (antenna for metal discrimination) 

Discriminate accurately metal targets!

The DDV system is a visual metal detector system to discriminate between different materials. This antenna for metal discrimination can be used to find out if there is iron, aluminium, gold or silver situated under the ground. You can adjust the discriminator of the DDV system to certain metals or to filter out nonvaluable metals which you don't like to detect. Than the metal detector coil will only react on the selected metal. For example it can be adjusted on gold to filter out other materials like iron. This probe is specially interesting for gold seekers and prospectors.

This powerful metal detector is useful to avoid digging for nonprecious metals or other material which you are not looking for. So you can find quickly your treasure. The metal detector find the targets and give the information via a audible sound over the headphones and also visually via the monitor of the eXp 4000.

Antenna for tunnel detection

Locate underground chambers or hidden rooms! 

This probe is a high resolution sensor which is focused on the research and detection of hidden voids like tunnels, rooms, chests, tombs, graves and others. You can receive a 3d underground image with this antenna, where voids are represented in particulary and with high resolution. Metals will also be visible in the scan image, but are not the main focus of this sensor. 

The antenna for tunnel detection is a 50cm vertical probe which can be carried in the hand. So it is very practicable in various terrains also in uneven grounds. The small size allows an accurate pinpointing of the exact position of a located underground anomaly. 

The antenna for tunnel detection is a must for all seekers who wants to look for cavities, bunkers, tunnel systems, tumulus, tombs and graves, treasure chambers, chests, boxes or non-metallic targets like vases or hollow-ware.

Features:

• Specialized on detection of voids
• High resolution probe
• Lightweight, easy to use and comfortable on-site
• Dimensions: 50 x 10 x 10 cm
• 2 years warranty

Super sensor

Deep search of precious metals!

The Super sensor is a multi task sensor which can be used in the operating modes Magnetometer, Ground Scan and Discrimination. The Super sensor can be used for high resolution ground scans (3d images) and for discriminating between ferrous (e.g. steel, iron) and nonferrous metals (e.g. gold, silver) in high depth. This one meter vertical probe is specialized on detecting precious metals and can locate small sized metals deeper than the gpr probes. Also it can discriminate between precious metals (e.g. gold, silver) and ferrous metals (iron) deeper than the DDV system, to avoid useless diggings in high depth. Because of the integrated sensor technology it offers good results even in hard, salty or mineralized soils. 

This one meter vertical probe can be hold in your hand easily and so is easily usable in areas with difficult access (bushes, trees, rocks) or uneven ground (stones, holes in the ground).

The Super sensor is an absolute must for all professional treasure hunters and gold seekers.

The Super Sensor has an integrated discrimination possibility to discriminate ferrous and nonferrous metals. No other metal detector can keep up with the Super Sensors depth penetration. A discrimination control prevents the user from digging out undesirable items like nails, cans or other trash. Features: Detects metals and voids High resolution scans Specialized on detection of metallic targets Discrimination possibility of ferrous metals, non-ferrous metals and cavities in combination with the software Visualizer 3D Lightweight Easy, comfortable handling Dimensions: 100 x 10 x 10 cm 2 years warranty

Thermoscan

Long Range Locator with infrared laser pointer!

The Thermoscan is a long range locator which recognize differences of temperatures on the surface of the ground. Due to this infrared measurement it is possible to locate voids like tunnels, treasure chambers, bunkers or caves under the ground. 

Combined with the metal detector eXp 4000 the Thermoscan can make a 3d image of a special area, without the need to walk over this specific area. The device works contactless and therefore a field can also be researched from far distances. So it is possible to scan rock faces, walls or other terrains to which you do not have any access. This is an important advantage if the field is impassable by the searcher.

Possible applications are:

• the detection of cavities (graves, tombs, chambers, chests, bunkers, tunnels, vases, hollow-ware ...),
• the visualization of the distribution of temperatures as well as
• the measurement of differences in temperatures.

The FS-Thermoscan stands up for its practicable usage and compact design. Create high resolution 3d graphics of the underground by measuring the differences in temperature on the surface of the ground.

Because of the integrated laser pointer pinpointed measurements and accurate positioning of hidden voids are possible. 

VLF emitter system (4 pieces)
(not available anymore)

Get the best results and the deepest penetration into the ground!

The VLF emitters can be placed on each corner of your scan area to improve the 3d image and receive the maximum possible penetration depth. So it is possible to locate small metallic objects deeper under the ground than without using these emitters. Additionally this system improves your scan result. All located metals under the ground will be visible more clearly in the three-dimensional graphic. 

VLF is the shortcut for Very Low Frequency which is a low wave frequency range. Usual VLF (Emitter) devices use a frequency in this range to send out an alternating magnetic field into the ground, which can be disturbed by a metallic target. This disturbance of the magnetic field can be analysed in detail and so it is possible to make a conclusion to targets situated under the surface.

The figure on the left side shows a located metallic target without using VLF emitters. The structure of the object is destroyed and not very accurate.	The figure on the right side shows the same measurement while using VLF emitters. The shape of the located target looks much clearer, also the background is straightened.

Advantages of the usage with FS Future Series
VLF emitters are optional available components which can be used to improve a measurement with the metal detecting device eXp 4000. VLF emitters send out very low frequencies to reinforce the magnetic field. Because of this amplification anomalies of the underground like metallic targets (gold, silver, copper etc.) becomes better visible.

The 3d image of the underground becomes more clearly than without using the VLF emitters. So you can better recognize the shape and structure of buried treasures.

Usage
One set of VLF emitters consists of 4 emitter sets with sending antenna which have to be placed on the ground, in every corner of your measuring area. Remove the antenna of every VLF emitter and place it on the ground in a distance of about 50 cm from the emitter main unit. Adjust every emitter to your current ground conditions and power it on. Now measure your area with the metal detecting instrument eXp 4000 in operating mode Ground Scan like usual.
