The VibeCore DW is a small, portable, 24v DC vibracorer

Two men stand on the deck of a boat with a long skinny coring device suspended from a cabling system on an A-frame.

Preparing the VibeCore DW.


The VibeCore DW is a small, portable, 24v DC vibracorer. With a 75lb head and the ability to run on a pair of car batteries, the VibeCore can take 3” core samples in unsleeved aluminum or polycarbonate tubing, up to 6m (20'). The VibeCore is a viable alternative for small vessels or remote fieldwork where a larger corer is not feasible.
