Zusammenfassung:	An anchoring system for a tool in a borehole is provided. The anchoring system comprising a tool body, anchoring members which are operable to extend from the tool body so as to deploy an anchor portion into contact with the borehole wall such that when deployed. The anchoring members act to support the tool body in a central region of the borehole. Moreover, the anchoring members are connected to an operating mechanism which links deployment of the anchoring members so as to distribute the anchoring force and position of the anchoring members in a controlled manner.
