Description
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.
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.
