1. An apparatus for the extraction of a smaller-than-pipe-diameter (STPD) device from a mainline pipe, the apparatus comprising:
a shaft having a proximal end and a distal end;
at least one slider attached to the shaft between the proximal end and the distal end;
a capture net attached to the shaft at the distal end, the capture net further comprising:
a hoop assembly, the hoop assembly further comprising:
a hoop further comprising:
a width that resists forces in a flow direction along the width; and
a thickness that is bendable in a radial direction through the thickness; and
a net assembly attached to the hoop assembly; and
a rotation gauge located on an actuator drive mechanism located on the proximal end of the shaft that indicates the orientation of the capture net within the mainline pipe.
