LORENZ DEEPMAX Z1 - made in Germany

Only three buttons are necessary to operate our new device.

The LORENZ DEEPMAX Z1 series detectors are some of the newest developments in the field of Pulse GBS metal detectors. It is probably one of the most sensitive and stable metal detecting devices of its kind presently available. The LORENZ DEEPMAX Z1 is the result of many years of research and development. A lot of efforts have been put into making this new product and especially in the new improved metal classifications and automatic ground balancing facilities.

The Pulse GBS (Pulse Ground Balancing System) is especially suitable for searching at depth. The performance of this electronic device is almost unaffected by salt water, most types of mineralized grounds or temperature changes. Specially designed electronics cancel out signals from the ground while offering stable signals from the metal objects. The DEEPMAX Z1 is therefore a reliable tool to locate at great depths even under the worst environmental conditions. A new improved circuit design suppresses interference from power lines and a power pulse technique produces very accurate signals to obtain very high detection depths.

The LORENZ DEEPMAX Z1 is a high quality specialist Detector and it is designed to be used with both, small or large coils. Large coils offer extreme depth capabilities for big metal objects because of the strong and deep going magnetic field produced. Small coils are preferably used while searching for small objects like single coins or gold nuggets.

This model offers a great range on non-ferrous metal objects in general. A very simple operation is guaranteed by a specially developed LC Display and a minimum amount of controls. At the same time this detector model offers a number of features which are new for a pulse metal detector. Quality electronics and very special designed electronic - circuitry produce benefits in terms of ease of use as well as sensitivity.

Data Logger includes GPS Hardware + Surfer 11 3D Software kit connecting to Lorenz Z1 for use with your Notebook or PC

Data Logger 

To generate color, image, surface or contour maps with the Lorenz DEEPMAX Z1, additional Hard- and Software is necessary. A very sophisticated 6 channel data logger function of the DEEPMAX Z1 metal detector will take simultaneously six channels of data when you go over the ground and stores the information into memory when this function is selected.

After recording field data the Surfer Software easily and accurately transforms the stored data into color, contour, surface, image or vector maps on a computer in minutes.

An additional Scripter Software will therefore automatically generate twelve maps with each field. Six are two-dimensional and six three-dimensional. The operator can therefore choose between different gridding and mapping methods.

The LORENZ DEEPMAX Z1 Data Logger Hard/ Software kit developed by Lorenz Detecting Systems is first of all easy to use, very accurately working and affordable. Only three controls of the DEEPMAX Z1 will make data acquisition a pleasure for both beginners and professionals like engineers, geologists, archaeologists, scientists and many more. The users will investigate mainly for waste disposal, meteorites, or lost aircrafts.

No non- sense functions will confuse the operator. Six different maps will be generated simultaneously when covering the ground with multiple tracks. Each scan/ map is different depending on the electronic analysis method and therefore will not only give different sensitivity ranges but can be the key to the probable kind of metal buried in the ground. There is clearly a difference in the signature metal objects and ground conditions will give for example.

Data Logger 

Areas of disturbances in the scans will directly lead to the different metals or ground signals and therefore can be classified in some ways. The operator therefore can use the different scans to his advantage in order to choose between the objects of most interest only by comparing the different scans/ maps. Three delay channels will produce maps with different sensitivity to small and large metal objects. Two ground channels will enable the operator to generate maps with no ground response but Z dimensions and directions for different decay curves of the eddy currents produced in a metal object. In addition the conductivity reading channel will display the delay of the eddy currents of each signal with a specific color to give further information on the probable kind of metal in the ground. No matter how strong the ground is mineralized or how many different metals are located in close proximity, this new device will ensure very good results even with difficult surrounding conditions. Faults produced by the operator or the environmental conditions like overload signals from nearby metal objects for example will be immediately seen when comparing the six channels. In addition GPS data is also recorded from a supplied GPS module to support the user with a compass function or to find the different fields after recording again.

Data Logger Data Logger

For the professional users additional Hard- and Software will be available for storing positioning data from GPS and several DEEPMAX Z1 detectors.

Although the detector can be used with smaller search heads the data logger function is mainly developed for larger metal objects being at least 6cm x 6cm in size. Therefore frames of 1m x 1m or even bigger should be in use to achieve best results.

To analyze the different pictures generated with the software refer to the following instructions. Compared to many other systems the Lorenz DEEPMAX Z1 will not only generate one or several graphic representations with different sensitivity ranges for the same metal objects but also gives additional information on the probable kind of metal being located.

The advantages of the six channel data logger are as follows:

    • False or overload data will be easily recognized on one or two of the maps. At the same time you will find useful data on at least one or two channels. When looking at the different maps/pictures select only these with no ground signals or with the stronger indications to avoid investigating on the small junk objects like foils, nails, magnetic soils or littered ground near the surface.
    • Some signals appear on one scan and disappear on others to give the operator more advanced information on the kind of metal (decay of the eddy currents) or the surrounding ground conditions.
    • It is possible to separate two or more different metal objects which give only one large indication in the Delay channels but two on the conductivity reading or Ground channels.
    • Some ferrous metal objects lying horizontally in the ground will cause a special triple signal with two high and a low indication when looking at the Ground channels.
    • Signals with a fast decay of the eddy current like foils, thin plates small nails will generate a negative peak in the vertical Z direction in Ground 1 and 2 channels, At the same time Metal objects with a long decay of the eddy currents like massive copper, bronze, aluminum or silver will cause a positive peak in Z direction. Ferrous metal objects will only give weaker signals and therefore a small indication in Z direction (in the three dimensional surface maps only)
    • When looking at the Ground channels most of the ground and some of the smaller ferrous items will no longer be displayed comparing them to the Delay channels.
    • On the conductivity reading pictures stronger signals which generate a conductivity reading will produce mainly a single color dot corresponding to the delay reading on the display of the DEEPMAX Z1. Neutral ground will cause a purple indication. Different nearby metal objects lying in close proximity will give different colors in most cases for better selection. 
    • See table of conductivity reading indications with a 1m x 1m frame coil:

35 cm DD-search coil
Separate transmitting and receiving windings offer more stable operation on soils with changing contents of iron oxides (minerals) in some cases. This coil can be used for most search applications. The FERROUS / NON-FERROUS target identification does work with these 26cm and 35cm double D search coils. Note: The electrical properties of the double D search coils may change when mechanical tension is produced in the coil when being used not properly. Search coils therefore are not covered by warranty for that reason. The same with the connecting cable which should be fastened with the belt strap first before connecting to the electronics unit to protect the same and to avoid broken cables.

26 cm search coil
This search coil was mainly developed for the location of very small metal objects like small nuggets or coin sized metal objects for example. The maximum detection depth is limited by the size of the object and the coil. In some cases it is easier to pinpoint very small metal fragments with this coil rather than with a double D- coil.
This search coil can be useful while pinpointing large metal objects which have been located with a frame mounted search coil before. Deeply buried metal objects can be out of the range of the small 26 cm search coil and therefore can only be detected with frame mounted search coils. The 26 cm search coil is waterproof and therefore can be used in saltwater for example.   *)
 
 
26 cm DD-search coil

A special double D version of this coil with separate transmitting and receiving windings is also available. This coil makes FERROUS / NON-FERROUS indications on the display of the DEEPMAX Z1 possible.
Depending on the type of ground sometimes DD- coils are less affected by extremely mineralized soils but pinpointing will be more difficult than with a single loop coil.   *)
 
 
35 cm search coil

This highly sensitive search coil has got very good depth capabilities on single coins and medium sized objects. Nuggets smaller than 5mm in diameter should rather be detected with a 26cm search coil than with this coil due to poor sensitivity to very small metal bits and pieces.   *)
 
 
35 cm DD-search coil
 - included with STANDARD delivery
Separate transmitting and receiving windings offer more stable operation on soils with changing contents of iron oxides (minerals) in some cases. This coil can be used for most search applications. The FERROUS / NON-FERROUS target identification does work with these 26cm and 35cm double D search coils. Note: The electrical properties of the double D search coils may change when mechanical tension is produced in the coil when being used not properly. Search coils therefore are not covered by warranty for that reason. The same with the connecting cable which should be fastened with the belt strap first before connecting to the electronics unit to protect the same and to avoid broken cables.   *)
 
 
45 cm search coil

This search coil can be operated by a single person with the S-rod-handle. It offers extreme depth ranges on either single coins or bigger objects buried deep in the ground. Depth ranges of more than 1 m for a metal object of the size of a soft drink can (0,33 l) or up to 50cm on a single gold coin with 25mm diameter make this coil interesting for a lot of different search and locating purposes.
Those extreme depth ranges on medium sized and bigger metal objects make frame mounted search coils unnecessary in some cases. Small items can be eliminated by increasing the distance between the coil and the ground. This 45 cm coil covers much more ground than a 26cm coil does and therefore makes very effective searching possible. Coins with a diameter of less than 15mm should rather be detected with smaller search coils.   *)
 
 
Universal cable coil 8 m perimeter

This extremely lightweight and easy to transport universal cable offers a variety of different search coils for different search applications. The cable coil has to be fixed with tape on a frame which can be made of PVC-tubes for example. The following search coil configurations are mainly useful for the location of metal objects with a surface of at least 6cm x 6cm or hand sized metal objects for example. Small metal pieces like single coins or nails will be indicated with poor sensitivity or will even be eliminated in some cases because they are out of the range of these frame coils. It is very easy to cover a large area with frame coils in a short time. This is especially useful when looking for bigger deeply buried metal objects while ignoring those smaller metal pieces at the surface. The following frame mounted search coils have to be carried by two persons with adjustable carrying straps. The search coil should be hold in parallel to the ground at a constant distance of 10 to 60 cm. The electronics control box should always be carried far away from the field of the search coil. It is also necessary not to wear any clothes, belts or shoes with metal when operating the detector to avoid false signals.
 
0,67 m x 0,67 m (3 windings) universal cable coil 8 m perimeter 
The 8m universal cable coil has to be arranged to a 3 winding search coil and has to be fixed on a 0,67m x 0,67m frame made of PVC-tubes for example.
Never use any metal screws for the construction of a frame! This is the smallest frame mounted search coil which offers extreme detection depths for smaller and medium sized objects. Metal fragments and some coins will still be indicated. The maximum detection depth is limited below the bigger frames but higher than with a 45cm diameter coil.
1m x 1m (2 windings) universal cable coil 8 m perimeter 
The universal cable coil has to be arranged to a 2 winding search coil and has to be fixed on a 1m x 1m PVC- tube frame for example.
Searching with the 1m x 1m frame coil is mainly advisable when looking for hand sized or bigger metal objects buried deep while ignoring small coins, nails and pieces of foil at the surface of the ground. The possible detection depths with this particular frame coil are very high compared with standard sine wave VLF-TR-detectors. This is one of the reasons why this particular search coil is used for most professional applications. Large areas can be covered in a short time. Best results are achieved with metal objects having a surface of at least 10cm x 10cm. Because of the size of the coil most of the small metal fragments will be ignored. However bigger nails can be identified with the conductivity/ time delay target identification. Most of the nails and other metal fragments can be easily eliminated by increasing the distance between the search coil and the ground. Even at distances of 50 cm or more there will only be negligible detection depth losses when locating large metal objects. This frame coil has to be carried by two persons with carrying straps.
The high depth range of the 1mx1m frame coil is achieved with intense and therefore deep going magnetic field transmitted. The detection depths listed in chapter 11 have been recorded with different DEL Delay and GND Ground settings. In some cases detection depths in wet, conducting ground are slightly higher or lower than listed.
For even higher detection depths use the 12m cable coil which can be arranged similarly to the 8m cable coil to 1m x 1m, 1,5m x 1,5m or 3m x 3m.
2m x 2m frame coil (1 winding) universal cable coil 8 m perimeter
The 8m universal cable coil has to be laid to a single turn on a metal free frame and has to be fixed with tape for example. This particular search coil covers four times as much ground as a 1m x 1m frame coil does. It should only be used when searching for metal objects with a surface of at least 20cm x 20cm pointing towards the coil. Smaller targets will be located less effectively than with a 1m x 1m frame. This is mainly because it will become more difficult to pinpoint those smaller objects with the large coil. The maximum detection depth is very high and can only be increased with the 12m cable coil arranged to a 1,5m x 1,5m or 3m x 3m frame. The 2 m x 2 m frame coil can be carried by two persons without any carrying straps at a distance of about 80cm above the ground. This is particularly useful when trying to ignore medium sized metal objects which are smaller than a horseshoe for example. Coins and nails will no longer be detected when doing this.
The 2m x 2m coil acts as a large aerial for medium wave transmitters. Therefore smaller frames like the 1m x 1m coil will be of better choice when working in urban areas. The next coil described will be less sensitive in general but won't suffer from electromagnetic interference of transmitters, power lines.
1m x 2m compensated frame coil (two separate windings) universal cable coil 8 m perimeter
In order to construct this compensated coil the 8m coil cable has to be laid to the figure of the shape of an eight (8) first. The coil cable has to be fixed on a 1m x 2m frame with a center part which divides the frame into two 1m x 1m frames. The cable has to be laid and fixed twice on the centre part as this is the middle of the eight (8). This type of frame mounted search coil is about 30% less sensitive than a 1m x 1m search coil. This is because of the opposite directions of the transmitted magnetic field. During the receiving phase the two windings of the eight do also work in opposite. Therefore interference and some ground indications are subtracted from each other and therefore eliminated. Interference from radio transmitters or power lines will be almost completely cancelled. This compensated 1m x 2m frame mounted search coil is of great advantage when locating metal objects in urban areas where interferences are often expected. This type of coil has a very poor sensitivity for small metal objects. The minimum surface of a metal plate should be 10cm x 10cm to ensure good results when working with this coil. The LORENZ DEEPMAX Z1 will work very stable with this particular coil.
The following described 1m x 1m double frame coil will give much higher detection depths namely almost the same sensitivity range as a single 1m x 1m frame but is also capable to cancel out said EMI (electromagnetic interferences).
 
 
Cable coil 12 meters perimeter

1m x 1m (three windings), 1,5m x 1,5m (two windings) or 3m x 3m (one winding)
Similar to the 8m universal cable coil this large cable coil can be arranged to three different frame coils by simply mounting one two or three windings on a metal free frame with tape for example. With the largest 3m x 3m frame coil the highest possible detection depths can be achieved. This is mainly possible because of specially developed electronics to eliminate low frequency interference and a power pulse circuit built-in the LORENZ DEEPMAX Z1. The high sensitivity for large and deeply buried metal objects and the simple elimination of smaller metal fragments make these three coils interesting. The shape of these large coils should be the same as with the other coils namely round or square. It is also possible to build elliptical or different shapes but this is only achieved at the expense of sensitivity. Anyway it is advisable to keep a distance of at least 20 to 80 cm constantly between the coil and the ground to reduce the amount of ground effects to a minimum when using these very large coils. In urban areas the amount of interferences produced from power lines will be higher than with smaller coils and therefore again the sensitivity might be reduced. The ground balancing system GND 1, 2, 3 should be changed to DEL 1-4 in some cases using these large coils because of the same reason. Some customers use these large frame coils with two similar coils mounted on each other at a distance of about 60 to 80 cm the same way as the differential double frame coil described before. A Y- adapter cable would be necessary doing this. A test making sure that both coils work in the same direction as described before would also be necessary.
 
 
1m x 1m frame coil with cable inside tubes
 - included in STANDARD delivery
This is a very user friendly 1m x 1m coil with the same electrical properties as the 8m universal cable coil with two windings as described before. The main advantage of this particular search coil is its simple assembly, which can be performed in a few steps. The disassembled coil is easy to transport and will always be ready for use.
The coil cable is protected inside the tubes and therefore can be used even under the worst environmental conditions. Two adjustable carrying straps are supplied with every frame coil.
 
 
1m x 1m double frame coil kit

This specially designed double frame coil kit basically consists of two 1m x 1m frame coils mounted on each other at a distance of approximately 60 cm. Because of its ability to cancel out interferences from power lines or radio transmitters it can be used in urban areas where single loop coils will suffer from false signals and poor sensitivity when electromagnetic interferences are present.
The two coils receive the same amount of interference but work in opposite directions. Therefore almost any interference is subtracted from each other while signals from the ground or metal objects will pass to the electronics. It is important that the components of the double frame kit are put together in the right order as described below. The available kit consists of the following components: two 1m x 1m frame coils; four black mounting devices 0,6m length; one Y adapter cable with three connectors; two carrying straps.
The two 1m x 1m frames have to be mounted on each other via the four mounting devices. They will automatically lock when pressing them together.
Please make sure that both frames go in the same direction, so that the two yellow marks are pointing to each other the same way! Afterwards the marked Y adapter plug has to be connected to the lower frame which points to the ground. The second frame has to be connected to the other adapter plug. The third connector has to be connected to the electronics control box.
Note: It is advisable to make an operating test where the lower search coil pointing to the ground gives a signal when approaching to a metal piece located on the ground and the upper coil will cause a decay of the signal when a metal piece is approaching from the top towards the coil. This could only be tested with DEL Delay settings and turned off AUTO 0.
The sensitivity of this double frame coil is almost the same as with the 1m x 1m single loop frame coil. This coil does only suffer from a very weak sensitivity reduction of less than 10 % for very deep and large metal objects. Especially when working in the GND Ground mode it is very useful to work with this particular search coil due to very stable and therefore sensitive operation.
