![]() ![]() Its top lids open wide to minimise the frontal shock wave as it is lowered.ġ97-C12 (large) is substantial enough to need no extra weights. Standard Methods recommends it for general sampling.ġ96-F62 (tall) is recommended by Standard Methods for larger samples in softer bottoms, particularly uppermost, fine, bottom materials. ![]() Wide base yields good stability despite its light weightġ96-B12 (standard) is the most versatile due to its portability.Heavy duty springs on tall and large versions.Sampler and cases also available separately.Kits include 45-B10 messenger, 62-C15 line and case.Extension handles replace messengers in shallow water.Extra weights fit standard and tall Ekmans.The closing springs easily unhook from their loaded position for safe handling during transportation and storage. They close during retrieval and are held shut by water pressure to reduce washout. Two thin, hinged overlapping lids on top open during descent to let water pass through. It is very reliable, has few working parts and is the best of its type in the field. Lower till the grab hits the bottom and send a messenger down the line, allowing the springs to close the scoops.Ī distinguishing feature is the messenger-operated scoop release mechanism. Set the springs over the knobs and pull the jaws apart. To operate, attach to a line and pass it through the trip mechanism.
