General Information

The Vallon VX1 is an extremely rugged differential magnetometer, designed as adjustment-free tension-band probe, for the detection of ferrous objects.

The VX1 combines high detection sensitivity with ease of operation. Tested according to MIL-specs it is suitable for use under all environmental conditions.

By attaching the control unit to the cable drum the handheld VX1 is easily transformed into a very compact set for borehole detection. The cable drum is already equipped with battery compartments. The probe of the VX1, the VSM, is then guided on a rugged borehole cable.
