Usually, mine detectors are metal detectors using electromagnetic induction techniques based on either the continuous wave or the pulse induction principle. Vallon original designs in 1965 were based on the continuous wave technique and since 1983 have employed the pulse induction technique.
Vallon metal detectors have a special soil program in order to adapt worldwide the detector to the local soil conditions. The soil program suppresses the undesirable ground effects nearly completely.
Easy operation and a rigid design ensure reliable operation for professional mine and ordnance clearing.
Since 2005, Vallon also offers a Dual Sensor Detector, the MINEHOUND VMR2 which has been updated to the current version MINEHOUND VMR3. This innovative advanced technology detector integrates a leading-edge ground penetrating radar (GPR) produced by Cobham Technical Services into a high-performance metal detector from Vallon. The unit has been designed specifically for use in the most challenging demining clearance operations of metal and metal-free objects and provides significant improvements in the efficiency of clearance.
The MINEHOUND VMR3 is simple to use and provides the operator with clear audio signals to alert the presence of a potential mine threat. When a threat is located, the MD audio provides accurate position information and mass of metal indication. The GPR audio then provides additional position and depth information, and gauges the radar cross-section of the target. Both detectors can be used separately or together. The GPR responds to even the smallest flush buried object (diameter > 5 cm), but not to smaller metal fragments. This means that metallic clutter such as bullet casings, small arms rounds and shrapnel, which commonly causes false alarms, is rejected by the system.
