This manually-driven, side-filling sampler collects discrete, uncompressed samples from rivers, lakes, wetlands, and estuaries. The single-moving part, chambered-type borer collects quality samples which are not compressed or shortened during recovery, unlike samples taken with end-filling core samplers. Sampling is easy. Simply deploy the borer ( in the closed position) to the desired depth. The bore is rotated clockwise 180° so that the sharpened edge of the chamber cuts a semi-cylindrical sediment core which is contained by the pivotal cover plate. During retrieval, the cover plate’ s counterclockwise rotation extrudes the undisturbed sample. Ideal for use in woody peat, sand, silt, and clay. Borer measures 5 cm in diameter and 50 cm in length with a sample volume of 10 ml/ cm.

The optional bronze slide hammer assembly ( sold separately) helps you drive and retrieve the borer in compact deposits. Use the lightweight, buoyant aluminum holobar extension rods for one-man operation of the sampler from a boat. Additional rods ( 4.0 cm diameter) are available in two lengths, 1.2 m and 2.4 m. Borer includes stainless steel borer head, two 1.2 m aluminum holobar extension rods, turning handle, carrying case, and reference materials.
