Description

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.

In combination with an optional SEPOS®-detector, the high-performance SEPOS® positioning system provides increased data quality thanks to its ability to compensate speed changes during data recording in boreholes.
