This is a typical Mole Plough which is used to lay 16mm or 7mm duct in fields. This normally will be laid alongside field boundaries at approximately 300mm depth. This Mole Plough cuts the slit and lays the duct and covers the exposed duct, all in one operation, so that within a few hours, there is little or no sign of the duct on the surface.
The picture on the right shows the external box used by B4RN to feed the fibre through the gas trap and into the building.
