Mine Kafon

The copy on the website suggests it's a mine clearing device but it doesn't seem you can use these to methodically clear a tract of land in order to 'reclaim' it - the paths that these things take are subject to winds and the terrain. Also there's the issue of retrieving the device to repair it and then if you can't retrieve it, there's the issue of these things littering their debris everywhere.

Then at the end of the video he says that it's a tool for local peoples to "cheaply survey the danger in their own environment". This makes more sense. If rolling this thing over a piece of land causes a detonation then you know the area around the detonation is likely to contain more mines so you can avoid that area.

Maybe someone with more insight or a better understanding can chime in.
