GAOTON Series 150 Overshot consists of three outside parts: Top Sub, Bowl, and Standard Guide. The Basic Overshot may be dressed with either of two sets of internal parts, if the fish diameter is near the maximum catch of the Overshot, a Spiral Grapple, Spiral Grapple Control, and Type “A” Packer are used. If the fish diameter is considerably below maximum catch size (½” or more) a Basket Grapple and a Mill Control Packer are used.

TIANHE Series 10 Sucker Rod Overshot is a professional fishing tool, designed for engaging and retrieving sucker rods, couplings, and other tubular from inside tubing strings.

TIANHE Series 10 Sucker Rod Overshot consists of a Top Sub, Bowl, Grapple, and a Guide. According to the size of the fish, there are two types of grapples available: Basket Grapple or Spiral Grapple. TIANHE Series 10 is a simply tool to use, no matter engaging or releasing operation, in fact just need to rotate the  fishing string on right hand.

When overshot nears the top of the fish, slowly rotate to the right as the overshot is lowered over the fish. After the fish is engaged,allow right-hand torque to release from the fishing string. Then raise the fish by pulling upward on the fishing string.

Bump down or drop the weight of the fishing string against the Overshot to break the hold of the grapple within the Bowl. Elevate the fishing string while slowly rotating it to the right until the Overshot has cleared the fish.

Because it does happen, just about every well driller and most plumbers who work on wells have a collection of grabbing devices, some of them home made, that can be lowered into the well to grapple around and grab on to the upper end of what now sits deep down in the well casing. It may take a few trials, but eventually they get stuff out by that method.

Overshoots or Overshots are fishing devices that fit over the exterior of the well pipe and then grab onto the well pipe exterior to enable lifting the pipe.

Logan Oil Tools calls these "external catch" devices. [12] The overshot may be a metal mesh device, or a spiral device, one or more round or oval loops, or similar devices that grab on to the pipe exterior. The overshot was invented by Bowen in 1935.

Cameras, Well-Bore Inspection - a well bore inspection camera can be lowered into the well to give a better understanding of exactly where your dropped obstruction lies and how to grapple-it.

A home-made "corkscrew" that increases in diameter towards its upper end, affixed to the end of a rigid pipe can also be pushed into the interior (or with some grapplers the outside) of the pipe in the well, turned until it grabs the pipe. I"m not sure this method will be strong enough to lift many feet of pipe in the well.

Elevators: Well pipe grapplers, well pipe elevators, or well pipe grabbers that will grab onto plastic pipe or iron pipe down inside of a well casing are sometimes home made based on designs such as the items listed above. Shown above are a pair of (green) well pipe elevators, and below, a pair (red) casing lifters provided by Hole Products.

Overshot mesh well pipe or item retrievers for fishing stuff out of a well: the most effective tools we know about for pulling lost well pipes out of a drilled well are various versions of overshots. Overshots, an "overshoot" type tool, are a bit easier to get over the outside of a well pipe than spear type tools are to get into the well pipe, unless the upper end of the pipe is near the top of the well.

Some supplies use the term "recovery bell" for overshots. The overshot is a cylindrical or conical shaped (bell shaped) device lowered over the upper end of a pipe to be retrieved from a well. Some companies (Schlumberger) produce a releasing overshot or overshots used for jarring or stuck material backoff operations.

The overshot is lowered over the end of the pipe in the well. If there is enough friction around the object the braided sleeve will contract and grab the object when the line is pulled up - like that braided rush "chinese finger trap" trick we played with as kids.

The overshot is attached to the end of a drilling rod or in the water well industry to the end of a section of well piping that is lowerd into the bore hole.

Some overshots include hardened self-cutting threads that will grab onto the upper end of a well pipe that has been dropped into the well borehole, thus allowing the pipe to be retrieved.
