MDETECTORS Ultimate set for searchers
[250010110001]
894.48EUR 715.58EUR

In this set are included the both detectors which are ideal for searching all types of objects, namely pulse-induction TRAK TERA 2 with frame 1.2x1.2m and VLF detector Golden Mask 4 PRO S with 30x25cm coil.
Both detectors can be used alone, but complement each other and they are a perfect combination. Use the frame to find large objects buried very deeply, then turn on the Golden Mask and center the signal, and also know what kind of metal it is.

Trak Terra 2 is a pulse-induction detector, including both dynamic and static mode of operation. This mode is a convenience for the user when the place is small and motion is not possible.
Golden Mask 4 PRO S is a very good coin detector that uses automatic and manual ground balance. It works at 18khz and has a high recovery speed. In addition to this, a small coil (20x15cm) can be purchased and it is perfect for searching for nugget gold. Below, see the detailed reviews of the detectors:

THRACE TERRA 2 VER 2.2 is a digital pulse-induction metal detector for detecting deeply buried in the ground metal objects. The device is simple constructed and easy to work with. The detector rewires almost no maintenance other than charging the battery when necessary.

THRACE - TERRA 2 is a professional PULSE-INDUCTION (PI) system which incorporates a large search coil (one-meter by one-meter as standard equipment) for the main purpose of finding large objects at great depths. These detection depths can almost be compared with those of magnetometers, which can detect nothing but ferromagnetic objects. Another great advantage of using the THRACE - TERRA 2 together with the large search coil is being able to cover a large area in a short period of time. The actual search coil is encased in a square plastic frame (PVC tubing) and can be carried by two persons.
Using the PI-principle offers some decisive advantages.
First, the search coil is not part of a resonant circuit as it is the case with VLF detectors and can, therefore, be of almost any size and shape. This is absolutely necessary in order to increase the location depth considerably. In the second place there is a timely discoupling between the transmitting and the receiving phase which makes it possible to work with far greater
transmission power.
A further advantage is that small objects like bottle caps, pull tabs, pieces
of aluminum foil, but also single coins are naturally rejected while using the large search coils.
But still the THRACE - TERRA 2 is an easy-to-operate metal detector: you only have to deal with four simple controls, of which you need just one while normal operation.
Objects are simultaneously indicated by a meter on the screen and by an audio signal, which increases in frequency while approaching the object. The audio response has a very wide frequency range in order to avoid signal saturation when the search coil approaches a very close object. This makes it easy to pinpoint the exact location.
The function of the THRACE - TERRA 2 is divided into two time intervals:

Transmission Phase
A strong duty current is flowing through the search coil about 600 times per second. The linearly increasing current builds up a primary magnetic field which radiates. The current is abruptly cut off after a certain time, so that the primary magnetic field collapses quickly causing so-called eddy currents in the metal object. Strength and duration of these eddy currents depend on the electrical conductivity, size and shape of the object. After a short time delay the search coil is connected to the receiver input.
Receiving phase
The decay of the eddy currents in the object produces a secondary magnetic field, which is radiated by the object. This secondary magnetic field has its effect also on the coil and here induces very low voltages, which are amplified and displayed by a meter and an audio signal. Obviously the detection range has physical limits, because these voltages are extremely weak and can be obscured by external magnetic fields.

THRACE - TERRA2

THRACE - TERRA2 parts for control
To achieve maximum depth of searching, the device must be set according to this manual. Also make sure that you are not around large metal objects - wire mesh, pipes, cables, lines, etc.
DO NOT TEST THE DETECTOR INDOOR!
Assemble the search frame and plug the connecting cable to the appropriate connector on the back panel of metal detector.
You will need at least 40 hours of practice to be sure you can really use all of the detectors’ functions.
You should know that if you haven’t used before a pulse induction detector, you will need some time to get used to the slower speed with it.
The synchronization work with the frame between the two operators is very important. The one who works with the search frame is responsible for setting the time and the distance between the frame and the land, while the other one has the role of “air cushion”, he is responsible for making the frame stable.
Normally the frame must be on 20cm. over the ground during operation.
