VXB3 – Magnetometer for use in boreholes

Magnetometer Kit, optimized for Continuous Use in Boreholes (± 300,000 nT)

  • High search performance
  • Rugged construction and low weight
  • Fast start-up
  • Simple operation
  • No sensor calibration required
  • Measuring range up to ± 300,000 nT
  • Mobile data acquisition and powerful analysis with VALLON software solutions

The VXB3 borehole detector together with its components provides an extremely reliable detection system for locating ferromagnetic objects in soil. As a result, it meets the toughest borehole detector performance requirements in civil and humanitarian ordnance removal.

The survey data can be displayed and reviewed immediately on a VALLON field computer as a curve or color-coded map. The data on the desktop PC can be analyzed in detail later using the VALLON software available as an option.

Wireless data transmission to the VALLON field computer also significantly faciliates the detection work.

Suitable for following searches ...

UXO :  Ideally suited for searching for relatively large ferromagnetic objects of all kinds (such as unexploded ordnance, etc.), particularly for data acquisition.
Underwater :  Also suited for underwater use.
Borehole :  Optimized for use in boreholes—optionally also with SEPOS® positioning system.
