A state indicator for determining the position of an extensible member in an extensible device. The status indicator is configured to reduce the fluid path extending through a portion of the cross-sectional area of that in extension device can be extended parts in the extended position when the increase of fluid pressure within the fluid path. By determining the fluid path within the pressure, people can determine the status indicator position within the fluid path and thus to determine extension device extension parts in the extended position or the retracted position.
