Fourth Generation: Metal Detector with Exchangeable Search Coil for Large-Scale Mine Clearing Projects

  • Optimized ergonomics for daily long-term operation in humanitarian and military demining
  • Flexible application optimization thanks to exchangeable search coils
  • VALLON UXO firmware in combination with UXO search coils VS30 and VS60
  • Detection of material and wires with low conductivity
  • Pinpoint button for a higher degree of location detection accuracy
  • Integrated GNSS for automatic and manual storage of waypoints
  • Infrared LED display for use with night vision devices and vibration alarm
  • Bluetooth® and WLAN interface to internal web server for personal device settings

The VMH4 – the successor to the VMH3/VMH3CS – is the ideal work tool for humanitarian demining organizations and armed forces.

New features such as the integrated web server and GNSS simplify planning and monitoring of large-scale mine clearing projects. The VMH4 is suited for all soils and shallow waters.

Using the advanced detection modes, materials and wires with low conductivity are also easier to detect than ever. The VMH4 demonstrates its outstanding capabilities in the detection of improvised explosive devices (IED) in particular.

The combination of mechanical durability, intuitive operation and maximum detection sensitivity leave the user nothing to be desired. Getting started just requires adjusting the length of the telescoping bar.

Another special feature of this new detector generation is that rechargeable batteries can also be charged right in the device, either with a 110 – 240 V/50 – 60 Hz AC adapter or on a 10 – 30 V vehicle on-board power supply.

Suitable for following searches ...

Mines :  Suited for mine detection. Thanks to maximum sensitivity, also responds to mines with low metal content.
UXO* :  Suited for searching for all types of metal (e. g. shells, grenades, submunitions, etc.) near the surface. Thanks to optionally available UXO search coils, it is also ideal for searching for objects at moderate depths.
IEDs :  Suited for searching for objects with low conductivity and the components typical of improvised explosive devices (e.g. wires and cables).
