Jack's Protector Surveyor

Jack's Protector Surveyor is a unique surveyor in Borderlands 2. It is an advanced shield surveyor that is tasked with the mission to provide an impenetrable golden shield to Handsome Jack during a later phase of the fight with him. While the protector surveyor is actively providing the shield, Jack himself will effectively be rendered invulnerable, although the protector surveyor itself has a structure comparable to that of a badass shield surveyor.
