A target base (10) for attaching an apparatus (13) to an object (11) has a substantially rigid body (12) with a mount surface (14) adapted to couple the apparatus (13) to the body (12), and a base surface. A suction cup (46) affixed to the base surface (18) of the target base (10) has a suction cavity (62) defined by a deformable sealing lip (64) at the perimeter of the suction cup (46). The sealing lip (64) and suction cavity (62) form with the object (11) a vacuum chamber (66). A vacuum system (44) includes vacuum passages (50, 52) for communicating a vacuum pressure to the vacuum chamber (66). One or more contact members (60) are affixed to the body and have contact surfaces which engage the object (11) to provide consistent off-set positioning of the target base (10) with respect to the object (11).
