13. A method for moving a selected downhole tool comprising:
running an object having a housing,
a cone movably received in the housing;
a piston body fixedly attached to the cone such that the movement of the piston body causes the same movement of the cone relative to the housing;
a valve disposed as a part of the object and separating hydrostatic pressure from pressure at an interface between the housing and the piston body; and
a trigger configured to open the valve at a selected circumstance into a borehole;
counting features in the borehole using a sensor in the object;
opening the valve at a selected count;
flooding the interface with hydrostatic pressure;
driving the piston body away from the housing; and
moving a radially expandable shoulder member toward a larger diameter end of the cone.
