VMH4-VS20/VS25 – Metal detector, olive

4th Generation Metal Detector with Exchangeable Search Coil

Discover VMH4

  • Optimized ergonomics for daily long-term operation in humanitarian and military demining
  • Flexible application optimization thanks to exchangeable search coils
  • Detection of material with low conductivity and wires
  • VALLON UXO mode
  • Button operated pinpoint function
  • Integrated GNSS for automatic and manual storage of waypoints
  • Infrared LED display for use with night vision devices and vibration alarm
  • Bluetooth® and Wi-Fi interface for cable-free access to the integrated web server
  • Also available as VMH4L with increased battery operating time at slightly higher weight

The VMH4—the successor to the VMH3—is the ideal work tool for humanitarian demining organizations.

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.

The VMH4 demonstrates its outstanding capabilities in the detection of improvised explosive devices (IEDs) in particular.

This detector is also available with the larger search coil VS25 with a diameter of 25 cm.

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.

The VMH4 metal detector is also available as VMH4L. It offers an increased battery operating time at a slightly higher weight by using four disposable/rechargeable batteries.

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 of all types of metal (e. g. shells, grenades, submunitions, etc.) near the surface. Thanks to optionally available UXO search coils, also for searching of objects at moderate depths.*
IED* :  Suited for searching of objects with low conductivity and the components typical of improvised explosive devices (e. g. wires and cables).
