Eggshell Core Catchers Work Well with Liner-Type Hand Corers
Eggshell Core Catchers fit between the bottom of a threaded core tube or liner tube and the nosepiece. Core catchers help hold samplers in the core tube that otherwise might be lost during retrieval. When the core sampler descends, fingers are forced open. When the core sampler is being retrieved, the fingers close. Pkg. of 3.
