For the first time to use ground metal detectors began in the 60 's in the United States and Great Britain, and by 1980, the popularity of metal detectors for finding gold nuggets reached its peak. In those days, almost all metal detectors were imported from United States to Australia. Soon it became clear that European and American technology are powerless before the Australian an abundance of hot stones and heavy soils-regular satellites of gold, and thus a prerequisite for the development of its own technology.
In the year 1985 in Adelaide (Australia) was registered place of business of MINELAB Electronics in search technology development of metal. Minelab-name is the abbreviation of "mining laboratory", literally, "laboratory of the mining industry". In April 1986, was issued the first metal detector from Minelab, 15000 Goldseeker "GS". In the next two years in Australia, has sold more than 8 million metal detectors of this model. The main advantage of Goldseeker was his ability to compensate for especially heavy soils with high salinity and an abundance of hot stones.
This device is different from the import of metal detectors and features and price. Continued research led to be born of a radically new technology, AGT (Automatic Ground Tracking), which means "automatic setting on the ground." The first metal detector with a new compensation scheme soil AGT became GT 16000 Ground Tracker, released in the year 1987. This device has received international recognition and has been exported successfully for several years in the United Kingdom, Sweden, France, Holland, Brazil, New Zealand, the United States and the Philippines. Soon GT 16000 Ground Tracker was upgraded in the 16000 FT Fast Tracker, and then, in 1993, the out model XT 17000 frequency with manual 32 and 6.4 kHz.
It was the first in the world the model metal detector, which uses the phase measurement multi frequency detection technology to detect equally well in both large and small goals, lying deep in the soil. In 1995, was released a new pulse metal detector SD2000. This event marked the beginning of the production of the most popular series metal detector for detecting gold nuggets-SD 2000, SD 2100 (SD, SD2200) using unique technology MPS (hypersensitivity). The principle of technology transfer in soil-MPS stream variables of long and short pulses of magnetic field. The first model was the depth of the search the SD2000 2-4 times higher than the XT 17000, but, unfortunately, did not have a discriminator.
In 1999, the SD was equipped with discrimination, receiving the name SD2200D. Further this series of metal detector steel appliances GP Extreme, GP3000, GP3500, complemented by dual-voltage on the coil technology DVT, which significantly increased their sensitivity and improved the compensation land. In 2007, the series was already digital metal detector GPX 4000. Firm MINELAB conquered foreign markets and the question of the expansion of the product range. A new consumer-hunters. To create the techniques were applied better technology, which allowed the MINELAB become a leader in the production of metal detector for finding gold nuggets.
Technological innovations, and automatic tuning-out for soil AGT were significantly improved and enhanced. In 1994 year rolled off the Assembly line, the world's first multi-frequency metal detector to search for the treasure, coins and rarities Sovereign eXtra Sensitive (XS) and its equivalent of Excalibur, designed for underwater searches.
These models of metal detectors from CW single-frequency accurate discrimination, the opportunity to work on any, even the mineralized or saline soils without loss of depth and sensitivity. Multi-frequency metal detector were found not a single frequency, as all previous models, while at the same time 17-e frequencies, which allowed not only to better discriminate against the objective, but also increase the depth and sensitivity. Single-frequency metal working, for example, at high frequencies (25-70 kHz), well find small items, but have a small search depth. Low-frequency (3-15 kHz) allow you to find deep where the goal, but are less sensitive to small targets.
Continuing to develop a series of metal detectors, in January 2000, the MINELAB has released 28-mi frequency Explorer XS with full frequency spectrum frequencies from 1.5 up to 100 kHz. This model represents all the previous work , AGT-setting on the ground, DoubleD reel, semi-automatic tuning sensitivity and a new method of double discrimination on the conductivity and the inductance. A new model of metal detector was equipped with a powerful microprocessor and LCD display, allowing it to accurately identify the type of metal, size and depth of purpose.
Since 2000, the Explorer has undergone some changes in the software and went from the first Model Explorer S-Explorer XS-Explorer II to the modern Explorer SE. today, the Explorer is the best-selling model in the world. The novelty of 2006 year was the new technology VELFX, which replaced the analog signal processing scheme for digital standard. New silent digital technology not only succeeded in reducing weight and consumption of energy, but also increased the possibility of single frequency metal detector. Model X-Terra 70 which provides VELFX, became truly universal and inexpensive metal detector to search for as treasures and gold nuggets.
For the further development of the company required considerable means, Therefore, the decision was made to sell not found further application of double frequency technology company. Based on this technology, white has established its two-frequency Spectrum DFX and MINELAB by opened its factory in Europe, in Ireland. Today MINELAB is the undisputed leader in the production and sales of metal detectors. More than 80% of Australian metal detectors MINELAB detectors are. There are nearly 40 offices. More than half of the total number of sold metal detectors MINELAB sold abroad. The company's popularity is growing around the world thanks to the fact that the works of MINELAB technology and consumer desires. Produced by products being sold on every continent of the world. Confirmation of the company's rapid growth is the fact that in the year 2003 she was at 14 place in Ireland on the pace of growth in the international market.
