Hand Corer with liner

Hand Corer 2in

Intended for shallow coring in fresh, salt or brackish waters, this corer is remarkably simple to use. Merely push it into bottom sediments using handles on the head assembly. After it penetrates the bottom, twist or pull it free to retrieve your sample. In deeper water, attach a 5 – 15’ extension handle to the head. In deeper water yet, you can drop it by attaching a line to a clevis on the head.

The hand corer works by creating a partial vacuum which holds the sample in place and helps prevent washout.

As the tube is pulled up, the polyurethane flutter valve on the head tightly seals sampler. The core catcher helps prevent wash-out from the bottom.

All Wildco® corers have interchangeable parts. This “building block” concept relies on the uniform use of coarse pipe thread. This thread provides an extremely reliable way to connect core tubes to sampling heads and nosepieces. While by their very nature these threads can become dirty and jam, they can be rinsed in water and used again. No pipe wrenches needed – a boon in the field.

Wildco® hand and Ogeechee™ corers are designed to be lowered on a taut line or cable into the substrate. They are not designed to be dropped because they are top-heavy and can easily tip over. While some customers tell us they obtain a good sample by a free drop on a loose line up to 20-30” (7-10 m), to accomplish this you must keep the sampler entirely in water, still and vertical when dropped. This cannot be attempted using bricks or cement blocks as weights due to the need to keep the core tube balanced and vertical.
