To mechanically function the tool, an axial downward load (in excess of the Spring force) enables the Grapple to automatically engage the fish. The Spring then pushes the Grapple back to the supported position, and an applied axial load causes the Grapple to bite into the fish, this over pull will verify engagement.
To release, fluid flow through a Nozzle fitted to the nose of the Core creates an internal pressure which pumps the Grapple back to the de-supported position enabling the Grapple to be pulled free from the fish. The pressure at which activation occurs is adjusted by simply changing out the Nozzle orifice dia.
