The AMS all stainless steel Ekman dredge is spring-loaded with a messenger that travels down the rope and trips the dredge to close. The 6” x 6” x 6” Ekman Dredge is used for sampling benthic communities inhabiting soft bottomed aquatic environments. Hinged upper doors swing open as the dredge is lowered, allowing water to pass through and minimize shock wave. Stainless Steel Messenger closes dredge, preventing washout of the sample. A 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 carrying case, 100ft. 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. The handle is easy to install on the dredge.
