One of the most common tools used for any kind of fishing job is the bumper sub.

The tool’s design allows full torque and unrestricted fluid circulation at all times. The Logan Fishing Bumper Sub can bump up or down to engage or disengage overshots or spears, or be used as a feed-off tool in milling or cutting operations. Other typical operations include releasing stuck drill pipe, drill collars, tubing, test tools, and safety joints. The fishing bumper sub can be used in conjunction with an overshot or spear.
