VMF4 Metal Detector

General Information

The metal detector VMF4 is designed to meet the very specific needs of mine clearance professionals in military and humanitarian demining scenarios.
With its ground breaking mechanical concept it does not sacrifice ergonomy for transportability.
The VMF4 combines the best of the concepts and unfolds from a miniaturized bundle to a full grown ergonomic detector in seconds.
all the features a Vallon user expects from his detector are included. Ruggedness is paired with simple operation and extremely high sensetivity.
On all soils.
Under all conditions.
New technologies in combination with high degree of miniaturization allowed for new features like Bluetooth, integrated web-server and GPS.
And since the quality of threats in military scenarios changed, the VMF4 detects not only metals but also carbon rods frequently being used to trigger IEDs.
