VX1 – Magnetometer Kit “SEPOS®-Borehole with SEPOS®-Detector”

Modular UXO Detector Kit with SEPOS®-Borehole for precise Probe Position Determination

Your partner for innovative UXO solutions

  • Modular magnetometer system for UXO detection down to great depths
  • SEPOS® for precise probe position determination – thanks to optimal compensation for changes in speed during data recording
  • Increased data quality
  • Polarity dependent Alarm indication by LED and audio signal
  • Interfaces: USB, Bluetooth® and serial
  • Direct communication to VALLON Hard- and Software for datalogging

The VX1 is a modular UXO detector system for ferrous object detection. It is extremely rugged and offers high search sensitivity.

It offers easy operation and meets toughest demands in civil, humanitarian and military ordnance disposal. This versatile device quickly collects data in conjunction with data acquisition devices from VALLON. For professional data analysis and documentation, VALLON's product portfolio offers corresponding software solutions.

In addition, the detachable digital probe VSM4 offers the flexibility for use in all VALLON multichannel systems.

The high-performance SEPOS® positioning system provides increased data quality thanks to its ability to compensate speed changes during data recording.

Suitable for following searches ...

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