6” x 6” x 6” Dredge for sampling benthic communities inhabiting soft bottomed aquatic environments. Hinged upper doors swing open as dredge is lowered, allowing water to pass through and minimize shock wave. Stainless steel messenger closes dredge, preventing washout of sample. Cable release system, with bar grip, helps set dredge with greater safety. Dredge is constructed of stainless steel with special Heliarc welding for added strength and durability. A case, 100 feet of line, and messenger are included. Also available is a 5’ aluminum handle with trip head that can be used in place of the line for shallow water work. Easily installed on Ekman dredge.
