GPA 1000
After years of research and development with the GPA series, we successfully developed the new GPA 1000. Through specially developed high-performance sensors and microprocessor controlled calibration, we were able to improve the search performance a lot of times. The use of high-performance sensors is very difficult, because we must first neutralize the Earth's magnetic field through complex electronics. The automatic calibration is a micro processor monitored, so that the user can search without any settings. With a digital display, the sensor data and the calibration get displayed. With this search performance, you'll be able to reach soil changes up to 15 meters depth.


With the big search performance and the special 3D system with 5 basic colors, is the new GPA 1000 indispensable high-tech device for all treasure hunter.

The GPA 1000 is not only a metal detector, but can by measurements of soil changes, find the most items that are buried in the ground. (metals in separate color)The objects in the ground floor change this balance and the GPA 1000 can measure these changes by using the 3D-software. Thus you cansee the strength and the size of the change. The metals are changing the ground balance more than other materials (voids change the soil in the opposite direction), thus you can discover metals faster through color changes. A strong pulse induction metal detector with a digital metal distinction is included with the device.

On the front of the GPA 1000 is a digital display, with that switch you can check the calibration status and sensor data without a PC. Furthermore, the battery charge status can be read at any time. Above the USB port are two LEDs, which show the correct PC Connection.


The calibration happens by a microprocessor and it will be done automatically on each floor without settings.

The power supply is guaranteed by a built-in 2400 mAh NiMH accumulator which permits about 5 hours of operation. The provided quick charger can be recharged fully within 2-3 hours the battery. An external car recharger cable for the cigarette lighter is also included. Furthermore, a 110-volt adapter is included. For prolonged operation is a more powerful battery available.

Horizontal probe

Universal probe:
The horizontal probe consists of sophisticated microprocessor controlled sensors, that can measure the smallest soil change (metal in seperate color) to less than 1 nT.

The sensor data are sent by a 7-wire cable to the microcontroller and after calibration, the data are transfered by an AD converter to the PC. These data will be processed through a newly developed 3D software.

During the operation of the Ground Penetrating Analyzer (GPA 1000) the horizontal probe will be carried at the grab handle of the telescopic pole. The aluminum telescopic pole is height adjustable and can be demountable into three parts.

The horizontal probe is 45 cm (17.72")long and has a diameter of 7 cm (2.76"). With a weight of just 500 grams is a comfortable search ensured.


Super probe:

The Super probe is a very powerful probe, with about 30 percent more depth performance than the universal probe. The search with the super probe is a little difficult, because the magnetic direction should be aligned. The Super probe is 60 cm (23.62")long and has a diameter of 7 cm (2.76") and weighs approximately 600 g.


Metal discrimination
With an additional Electronics (gold scan) the metals can be discriminated.

The digital display of the additional electronics shows light metals such as aluminum to about 40, copper about 100 and gold up to 150.


Search with Live mode

It is useful to scan the areas grossly in the live mode first, to mark the important areas, and then in the 3D system precisely control.

In the case of a PC data loss, the customers has to present their serial number and customer number to get the software by email from our customer service. Each of the 3 software components are only in combination with our electronic unit and the serial number of the supplied PC functional. The 3-D representations and measuring data can be transferred to provided USB stick and be used for subsequent treatment on other PCs.
