ABSTRACT:
A ground probe apparatus includes a rod portion which includes a rod outer diameter. A handle portion is connected to a proximal end of the rod portion. A ground-penetrating tip portion is connected to a distal end of the rod portion. The ground,penetrating tip portion includes a tip end, and a wide-diameter portion is connected to the rod portion a predetermined distance from the tip end of the ground-penetrating tip portion. The wide-diameter portion has a wide-portion outer diameter which is greater than the rod outer diameter. The wide-diameter portion and the ground-penetrating tip portion may be combined into an integrated, unitary wide-diameter, tip assembly which can be selectively removed from and replaced on the rod portion. The wide-diameter portion includes a first tapered portion tapering toward the tip end and a second tapered portion tapering away from the tip end. The wide-diameter portion may be in a form of a wide-diameter sleeve that fits onto the rod portion the predetermined distance from the tip end of the ground-penetrating tip portion. The rod portion may include a first rod segment, a second rod segment, and a coupler segment connected between the first rod segment and the second rod segment. By not using either the first rod segment or the second rod segment and the coupler segment, the length of the rod portion can be shortened.
