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.

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.
