Abstract
In a first aspect the invention relates to a head for dredging comprising: a) a container having an open face at one end and closed end, b) an aperture at the closed end for connection to an extractor, c) at least one first water outlet connectable to a supply of water under pressure and to direct water below the container, in use water from the or each first water outlet being directed onto a water bed to disturb particulate material of the water bed whereby it mixes with ambient water and is drawn into the container and out through the aperture by said extractor.
