A buoyant net and object retrieval device, comprising: (a) a handle member sealed at both ends and having multiple mutually telescoping rigid plastic tubes, the larger tube at each telescoping junction of tubes being externally threaded; (b) packing gland means at the junction between adjacent tubes

A buoyant net and object retrieval device, comprising: (a) a handle member sealed at both ends and having multiple mutually telescoping rigid plastic tubes, the larger tube at each telescoping junction of tubes being externally threaded; (b) packing gland means at the junction between adjacent tubes, each packing gland means comprising a cylindrical metal body having a bore with a shoulder therein stepping the bore down from the diameter of the larger tube to that of the adjacent smaller tube, and the larger bore being threaded to screw onto the externally threaded tube and the smaller bore extending along the smaller tube beyond the shoulder, and packing means compressible between said shoulder and the end of the larger tube, the gland means being adjustable to seal the junction against entry of water and to lock the adjacent tubes together; (c) a fork member attached to one end of the handle member and having two pivot plates extending away from the handle in parallel spaced relationship; (d) a block member having one end extending between the plates and pivoted thereto by a pivot pin, and having a second end joined nonrotatively to the first end and spaced therefrom by a threaded neck; (e) the pivot plates having multiple straight locking edges, the locking edges on one plate being similar to and parallel to the locking edges on the other plate, and the threaded neck supporting a mating threaded sleeve, and said sleeve being positionable on said neck threads selectively to space the sleeve from the locking edges to permit pivoting of the block member about the pin or to tighten the sleeve against adjacent edges of the plates to lock the block member in a selected position; and (f) a net supporting frame member fixed to said second end of the block member, the frame member being made of rigid plastic tubing sealed at its ends and bent to form a substantially rectangular net opening shape, one corner of the frame member being fixed to said second end of the block member.
