Overshot
Technical Features
Sucker rod overshot is a professional fishing tool, designed for engaging and retrieving sucker rod, couplings, and other tubular from inside tubing strings.
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. It is a simply tool to use, no matter engaging or releasing operation, in fact just need to rotate the fishing string on right hand.
Engaging a fish
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.
Releasing a fish
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.
