ABSTRACT:
A spear and overshot are provided that use a plurality of collets. The collets are initially displaced by the fish until they are presented against a reduced diameter portion of the apparatus. At that point, the collets are inwardly attracted and the apparatus can be lowered into the fish or onto the fish. Further movement of the apparatus allows engagement of the fish onto the collets as the collets spring back to their original position with the fish trap above. Thereafter, should the fish need to be released, hydraulic pressure is applied within the apparatus shifting a body with respect to the collets allowing them again to be radially inwardly deflected for release of the fish.
