The Box Corers are simple and reliable corers for sampling an area of 0.25 m² (Mega-Box Corer) and 0.1 m² (Box Corer) of sediment with minimal disturbance and sample contamination. It's unique double shovel design allows easy access to the sediment for sub-sampling for subsequent scientific investigation.

The Corers are widely used for sampling in biological, chemical and geochemical applications as the relatively large block of sediment provides a large well preserved sample.

The Corers are easily deployed from a deck stand and can be lowered onto a standard lifeboat no-load release, which activates after sediment penetration. The box is closed, top and bottom, by two closely fitting shovels, mounted on pivot arms. Removable weights allow the corers to be used successfully in a range of sediment types.
