His design was accepted and 500 mine detectors were immedietely send to El Alamein when they doubled the speed of British army. During the war more than 100.000 of this type were produced, together with several hundred thousands of further developments of the mine detector (Mk. II, Mk. III and Mk IV). The Mine detectotr Polish Mk. III was used by the british army until 1995. In The History of Landmines, Mike Croll says The Polish detector had two coils, one of which was connected to an oscillator which generated an oscillating current of an acoustic frequency. The other coil was connected to an amplifier and a telephone. When the coils came into proximity to a metallic object the balance between the coils was upset and the telephone reported a signal. The equipment weighed just under 30 pounds and could be operated by one man. The Polish detector saw service throughout the war and the Mark 4c version was still used by the British Army until 1995.
