This is the grab to choose for soft, finely divided littoral bottoms that are free from vegetation, such as sticks and leaves (or with short, erect growth only) as well as intermixtures of sand, stones and other coarse debris. It specializes in taking quantitative and qualitative samples macroscopic bottom fauna to determine the productivity of soft bottoms, particularly those composed of finely divided muck, mud, ooze, submerged marl and fine peaty materials. Versatile and durable, it is suited for preliminary as well as more precise work. It is not recommended for rocky or sandy bottoms or moderate macrophyte growth because small pebbles or stems prevent proper jaw closure.
Two thin, hinged overlapping lids on top open during descent to let water pass through. They close during retrieval and are held shut by water pressure to reduce washout. The closing springs easily unhook from their loaded position for safe handling during transportation and storage.
