Once the profile is encountered, the flow path can be used to create a jetting action to wash debris from the profile. To engage the profile or the slick ID or OD fish, minimal set-down weight is applied, which moves the collet into the release position, allowing it to engage the fish.

The spear and overshot have a flow release feature that allows to release of a fish by pumping a pre-determined flowrate that will
