Flexible GPR solution with unique features

An integrated and flexible GPR solution with a rugged platform & an excellent detection capability. Optimize the system for specific projects by choosing from a wide range of GPR-antennas and measuring devices.

Through unique hyper stacking HDR technology, MALÅ GX offers fast data acquisition rates, with outstanding signal-to-noise ratio and depth penetration.

GPR-antennas with 4 different frequencies

MALÅ GroundExplorer (GX) can be customized for specific measurements by adding different antenna frequencies. For this solution there are 4 different antennas to choose from.

  • GX80
  • GX160
  • GX450
  • GX750

Besides flexibility, GX also delivers great performance and has a high standard outdoor visibility. Both qualities that comes from its fast 1.6 GHz Intel Atom processor and high-resolution display, on which the 32-bit data is presented.

MALÅ GX uses the HDR technology, which utilizes hyper stacking. A feature that leads to a reduction of random noise and the ability to use deep penetration without any loss of data quality.

Useful features that facilitates field measurements

All GPR antennas, that can be used with MALÅ GX, feature an integrated DGPS for a more accurate positioning. In addition to that, GX supports the use of external GPS and a wide range of distance measuring devices.

The new WiFi option enables wireless data collection, which makes it even easier to use in confined spaces and irregular landscapes. And to further simplify measurement out in the field, the easy-to-use controller has been equipped with a built-in battery

System configuration

Every MALÅ GX solution contains two separate components: the GX Controller and the GX antenna. These are connected either through a single cable or WiFi. MALÅ GX is typically configured as either a push- or pull system.

To configure a push-system, the MALÅ GX Controller and a MALÅ GX antenna are mounted on a Rough Terrain Cart.

To configure a pull-system, an encoder wheel is fitted to the mounting block on the back of the antenna. The GX Controller is then carried with the monitor holder and the antenna assembly can be pulled with a pulling handle or a strap.

The MALÅ GX flexible GPR antenna options are;  GX80, GX160, GX450, and GX750, all based on the latest HDR technology.
