The Seabed Terminal Impact Newton Gradiometer (STING) is a free-falling penetrometer probe used to assess seabed sediment composition and bearing strength.

A.G.O. Environmental sells the STING in association with Microsec R&D Inc, who helped develop its electronics.

Porous pots are low-cost, low-tech, rugged tools for self potential (SP) and induced polarization (IP) geophysical surveys for mineral exploration.  Also known as “non-polarizable electrodes.”

Dummy probes are important gear for testing borehole conditions to locate and avoid sections with high risk of jamming before sending down expensive equipment.  A.G.O.’s dummy headers feature a quick-release shear pin to release the dummy probe if it gets stuck in the borehole.
