Wildco K-B Series Heavy Corer with 20-inch Tube

Obtain Quantitative Samples in Demanding Environments with This Stainless Steel Corer

The K-B Heavy Corer with Case is your specialized tool for collecting sediment and fauna samples in deep water, especially at the water-bottom interface. Its design, optimized for obtaining samples of mobile benthic organisms like Tubificidae, incorporates a valve that remains open during descent, preventing pressure waves that might alert fauna. The messenger-activated closure allows you to control exactly when to capture the sample. This heavy version offers better penetration into compact substrates and comes fully equipped with a messenger, a 100-foot line, a rigid carrying case, and a liner kit.

Features

It is ideal for deep water, recommended for sampling at depths over 300 ft (100 m).

Its free-flow design minimizes sediment disturbance and does not alert fauna.

It offers you total control with its messenger-operated closure system to trigger sampling at the exact moment.

Its heavy version allows for more effective penetration into compact bottoms.

It features a 316 stainless steel head and tube for high durability in marine environments.

Its components are interchangeable with other Wildco® corers.

The complete kit includes a messenger, a 100 ft. line, a rigid case, liners, and core catchers.
