VMF4 – Compact Metal Detector, sand

Fourth Generation: Compact Metal Detector with Exchangeable Search Coil for Mine Clearing Projects

  • Ergonomically optimized for long-term operation in the humanitarian demining and military mine clearance
  • Foldable metal detector with small packing dimensions
  • 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
  • Infrared LED display for use with night vision devices and vibration alarm
  • Bluetooth® und Wi-Fi interface to internal web server for personal device settings

The foldable VMF4 metal detector has tiny packaging dimensions and offers the same excellent ergonomics as the VMH4 metal detector. It is ideal for both humanitarian demining and military mine clearance. This applies to all soils and shallow waters in a wide variety of conditions.

Using the advanced detection modes, materials and wires with low conductivityare also easier to detect than ever. It 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.

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).
