A positioning tool for moving an element in a flow path of a down hole system without actuating a pressure actuated device in the system. The positioning device includes a choke for restricting flow of fluid between the positioning device and the down hole system, a flow diversion path from the upper end of the positioning device to a lower end of the positioning device, and a valve allowing fluid to flow through the diversion path when the choke is proximate the pressure actuated device and blocking flow of through the diversion path when the choke is displaced from the pressure actuated device. The down hole system may be a flapper type fluid loss device with a pressure actuated opening prop.
