Afghanistan and Land Mines

Everyone who cares must know that Afghanistan, a place recently on our collective minds, is a place as littered with the actual sadness of exploded landmine victims and the potential sadness of unexploded landmines It is possible to fit the front of some armored vehicles with devices which look nothing so like a snowplow, in a v-shape, like a cattleprod. In the meantime, this plows their fields. Howabout a new device, combining both the simplicity of hand-held metal detector units with the efficacy of heavy industry? Two channels in parallel, each one meter wide, are cleared, 20-40 meters apart, the machine would travel on the channels, with the detector suspended between them.
