Abstract
In embodiments of the invention, a dredging head assembly uses vacuum only, or a combination of vacuum and flexible PVC tines, rather than the harsh digging and/or scraping features of conventional dredging equipment. Embodiments of the invention also provide a dredging head assembly that may be used in very shallow water. An embodiment of the invention includes a hose and wand to enable vacuuming around obstacles.
